Product Description
Application Description
For more information on
“Transfer Switch Panels,”
refer to Section 4 of this
catalog “Advanced
Residential Products.”
A transfer switch is a
critical component of any
emergency or standby power
system. When the normal
(preferred) source of power
is lost, a transfer switch
quickly and safely shifts the
load circuit from the normal
source of power to the
emergency (alternate) source
of power. This permits critical
loads to continue running
with minimal or no outage.
After the normal source of
power has been restored,
the retransfer process returns
the load circuit to the normal

Transfer Switches
Transfer Switch Equipment
Utility—Generator
Transfer switches are
traditionally applied between
a utility and a generator set
for emergency and standby
power systems.
Generator—Generator
Transfer switches are
sometimes applied between
two generator sets for
prime power use, often
in remote installations. In
such applications, source
power is periodically
alternated between the
generator sets to equally
share run time.
Service Entrance Rated
Transfer Switches
Modifying the molded
case switch in the transfer
switch by adding trip units
and optional ground fault,
along with adding the service
entrance option eliminates
the need for separate
upstream disconnect devices
and their respective power
interconnections. This means
the automatic transfer switch
(ATS) is installed directly
at the point of service
entrance, saving valuable
space and cost.
Built-In Protection
All Eaton molded case
switches are “self
protected,” such that under
extreme fault conditions,
the switch will open before
destroying itself. This
feature allows Eaton to
offer “Maintenance-Free
Contacts” on the molded
case transfer switch. The
molded case switches have
instantaneous magnetic
trip units installed in each
switch. These trips are not
accessible once installed by
the factory to eliminate field
tapering. The trips are set to
a minimum of 12 to 15 times
the rated current of the
molded case device, well
above any coordination set
points. This means they will
not interfere with the normal
operation of the distribution
system and will only trip if
something is very wrong.

Product Description

16
16
16
16
16
The automatic open transition
contactor-based transfer
switch is the most basic
design that will provide a
fully functioning automatic
transfer switch.
The power switching
operation of Eaton’s
contactor-based transfer
switches may be separated
into the following key
categories of:
●
16
16
16
●
16
16
16
16
16
16
16
Open in-phase transition—
break-before-make
operation utilizing an inphase monitor for source
synchronization
Open delayed transition—
break-before-make
operation utilizing a
programmable time delay
(true neutral position)
The open in-phase transition
utilizes a two-position
mechanism and the open
delayed transition utilizes a
three-position mechanism.
The mechanism used to
operate the Eaton electrical
contactor is a momentarily
energized solenoid consisting
of a stationary core and
a moving core that is
magnetically driven by
an electrical coil.
Application Description
The mechanism can be
electrically and mechanically
operated. The design is
such that the mechanism is
inherently interlocked so the
device cannot be closed on
the Source 1 and Source 2
at the same time under
any circumstances. When
switching from Source 1
to Source 2, or Source 2 to
Source 1, the mechanism
will only allow a break-beforemake operation.
An automatic open transition
transfer switch may be used
for those applications where
emergency backup power is
required, but a momentary
loss of power is acceptable
on the retransfer from
emergency to normal.
These contactor-based
designs can be applied
with the ATC-100 controller
up to 400A. The ATC-300
controller can be applied
for applications 40–1200A.
Applications needing
communication capability
require the ATC-800
controller.

Automatic Closed Transition, 40–1200A
16
Product Description
Application Description
Eaton’s closed transition
contactor-based automatic
transfer switch (CTC8) is
designed to avoid intentional
interruption of power when
both sources of power are
available by momentarily
paralleling both sources.
A transfer switch designed
for closed transition has
make-before-break contacts
that require the normal and
alternate sources to be
synchronized. The source
contacts on Eaton’s CTC8
will parallel for 100 ms or
less. The ATC-800 provides
all-phase undervoltage,
underfrequency, and
overvoltage and
overfrequency protection
as a standard. Consult with
the local utility company for
permission and to verify the
protection requirements as
each utility may have
different rules regarding
closed transition applications.
Protective relays may be
available as an option upon
request.
16
16

16

16
16
The ATC-800 is a
comprehensive, multifunction, microprocessorbased controller, offering
extensive monitoring, status
reporting and transfer control
operation.
The make-before-break
contact sequence coupled
with Eaton’s ATC-800
provides a transfer switch
that is useful in critical
standby power applications
available from 40–1200A.
16
16
16
16
Closed transition controls
The CTC8 accomplishes the
closed transition transfer by
monitoring the voltage and
frequency set point
conditions of both power
sources. Once the set point
conditions are met, the ATC800 controller will start the
closed transition
synchronization timer (TSCT).
The TSCT is adjustable from
1–60 minutes in duration.
This duration is the time
during which the ATC-800
controller will monitor the
phase angles to anticipate
when they will be within 8
electrical degrees. The closed
transition scheme is
anticipatory, allowing the
close contacts signal to be
initiated before the sources
are exactly in phase. If the
TSCT times out and the
transfer switch has not
reached synchronization, the
transfer switch will remain
connected to the current
power source and a failure to
transfer alarm will be
displayed.

provide emergency power to
life safety and other critical
loads where maintenance
of the main transfer switch,
without interruption of power
to the load, is either desirable
or required.
Application Description
Eaton’s Automatic Transfer
Switch is designed to provide
unmatched performance,
reliability and versatility for
critical standby power
applications. The switches
can be equipped with the
ATC-300 or ATC-800

Components
Front Access
Front access is a standard
feature. Source 1 (NORMAL)
Source and Load connections
are set up as standard top
entry and Source 2
(EMERGENCY) Source
connections as bottom entry.
These connections are
located in their own separate
compartments. These
connections can be relocated
in the field if necessary.
Multi-Tap Transformer
The industry-exclusive multitap system voltage selector
allows the transfer switch to
be applied on most system
voltages by proper insertion
of the selector plug.
Drawout Contactors
The ATS and the bypass
drawout cassette power
contactor designs are
identical and interchangeable.
This standard feature
allows the user the ability
to withdraw, maintain or
swap contactor assemblies,
providing redundancy of ATS
and bypass functions from
one contactor assembly to
the other.
Improved Safety
The unique Eaton design
includes separation
between control and
power components. The
ATS and bypass isolation
contactors are mounted in
separate compartments with
protective barriers between
them. This design prevents
the possibility of contact
with the rear-mounted
power connections to the
contactors. In addition, the
top and bottom entry have
separate compartment doors.
Ease of Maintenance
Transfer to the bypass power
contactor is easily initiated
and controlled via doormounted controls. Once
the transfer to the bypass
contactor is complete, the
ATS contactor is easily racked
out with the compartment
door closed. The ATS
contactor may then be tested
in the racked out position.
16.2
Ease of Transfer
The Eaton design allows the
operator to make a quick and
simple transfer from the ATS
power contactor to the
bypass contactor by initiating
the electrically operated
transfer via a two-position
switch. Door-mounted
indicating lights confirm
that a successful transfer
has taken place.
Dual ATS Capability
The controller on conventional
bypass isolation switches only
controls the ATS contactor.
The Eaton design allows the
switch controller to remain
active in both the ATS and
bypass modes, thus providing
control to either contactor.
This ability of the controller
to remain active and control
the bypass isolation contactor
provides “N+1” redundancy
of a second fully functioning
ATS, a feature unique
to Eaton.

Dual ATS
Multi-Tap Transformer
The industry-exclusive MultiTap system voltage selector
allows the transfer switch to
be applied on most system
voltages by proper insertion
of the selector plug.
Improved Safety
The unique Eaton design
includes separation
between control and
power components. The
ATS and bypass isolation
contactors are mounted in
separate compartments with
protective barriers between
them. This design prevents
the possibility of contact
with the rear-mounted
power connections to the
contactors. In addition, the
top and bottom entry have
separate compartment doors.
Drawout ATS and FixedMounted Bypass
The ATS is designed as a
drawout with the contactor
mounted in a cassette with
wheels. This allows the user
the ability to withdraw,
maintain, inspect and reinsert the ATS.
Ease of Maintenance
Transfer to the bypass power
contactor is easily initiated
and controlled via doormounted controls. Once
the transfer to the bypass
contactor is complete, the
ATS contactor is easily racked
out with the compartment
door closed. The ATS
contactor may then be tested
in the isolated position.
The bypass unit is designed
as a fixed-mounted design in
its own separate
compartment.
Bypass Isolation Switch
Components
Front Access
Front access is a standard
feature. Source 1 (NORMAL),
Source 2 (EMERGENCY) and
Load connections are set up
as bottom entry. These
connections are located in
their own separate
compartments.

Ease of Transfer
The Eaton design allows the
operator to make a quick and
simple transfer from the ATS
power contactor to the
bypass contactor by initiating
the electrically operated
transfer via a two-position
switch. Door-mounted
indicating lights confirm
that a successful transfer
has taken place.
Optional Dual ATS
Capability
The controller on conventional
bypass isolation switches only
controls the ATS contactor.
The Eaton design allows the
switch controller to remain
active in both the ATS and
bypass modes, thus providing
control to either contactor.
This ability of the controller
to remain active and control
the bypass isolation contactor
provides “N+1” redundancy
of a second fully functioning
ATS, a feature unique
to Eaton.

Molded Case Switches—Manual Wallmount
16
Description
Application Description
Eaton’s wallmount manually
operated transfer switches
are designed for a variety of
standby power applications
for critical loads. In the event
of a primary power source
interruption, the user can
manually transfer the load
circuits to the standby power
source. Once primary power
has been restored, the user
can manually transfer the
load circuits back to the
primary power source.
Manual transfer switches
cover applications ranging
from 30 to 1000A through
600 Vac for standard manual
configurations and open
transition.

16
Manual transfer switches
may be applied for those
application where a manually
initiated and manually
operated transfer is suitable.
The front door of the switch
must be opened to operate
the manual handle. The
design comes standard with
a deadfront design, allowing
safe manual transfer under
load. Should an application
require a service entrance
rating, then a non-automatic
or automatic design needs to
be selected.

Eaton’s wallmount nonautomatic transfer switches
are designed for a variety of
standby power applications
for critical loads.
In the event of a primary
power source interruption,
the user can manually
transfer the load circuits to
the standby power source
Application Description
through the use of an
external pushbutton. Once
primary power has been
restored, the user can
manually transfer the load
circuits back to the primary
power source through the
use of an external
pushbutton.

Non-automatic transfer
switches cover applications
ranging from 30–1000A
through 600 Vac for manual
configurations, open
transition, standard or
service entrance.
Non-automatic transfer
switches are manually
initiated, but electrically
operated designs. Front
door-mounted controls allow
the operator to initiate the
transfer. Overcurrent trips
may be added to the design
for either or both the normal
and emergency source.
Service entrance ratings
are available.

Molded Case Switches—Automatic Wallmount
Product Description
Eaton’s wallmount transfer
switches are designed for a
variety of standby power
applications for critical loads.
They provide flexibility,
reliability and value in a
compact package. In the
event of a primary power
source interruption, a transfer
switch provides an effective
means to transfer the load
circuits to an alternate power
source while reducing the
possibility of injury or
property damage.
Wallmount transfer switches
meet or exceed all industry
standards for endurance,
reliability and performance.
These breaker-based designs
can be applied with the
ATC-100, ATC-300 or
ATC-600 controllers.
Application Description
Suitable for emergency and
standby systems (all loads).

Basic Components of Automatic Transfer Switches
Eaton’s Superior Design Transfer
Switch Characteristics
Unmatched Performance
and Versatility
Eaton’s family of wallmount
transfer switches offers
unmatched performance,
versatility and value for
power switching applications.
At the heart of these designs
is Eaton’s molded case
switch, designed specifically
to meet UL 1008.
Superior Main
Contact Structure
All Eaton wallmount transfer
switches meet or exceed
the standards set forth in
UL 1008 and UL 489. No
other transfer switch
manufacturer has met the
rigid testing requirements
of this combination of
standards. Completely
enclosed contacts add a
measure of safety and
reliability. It also ensures
the integrity of the contact
assemblies and minimizes
the need for periodic
maintenance of the contacts,
reducing downtime.
Fast, Powerful and
Safe Power Switching
Mechanism
The power panel utilizes a
unidirectional gear motor
mechanism. The power panel
can be operated manually
under a FULL LOAD.
Molded Case Switch Features
●
True four-pole switched
neutral availability
●
Totally enclosed contact
assembly
Optional Integral Overcurrent
Protection Capability
For service entrance and
other applications, trip units
can be integrated into the
power switching section.
This eliminates the need
for separate upstream
protective devices, saving
cost and space.
Optional Thermal-Magnetic or
Electronic Trip Units
Molded Case Switch

Transfer Switches
Breaker-Based Designs
Mechanical Interlock
Wallmount transfer switches
feature a rear-mounted,
patented fail-safe mechanical
interlock to prevent paralleling
of sources. This is, in addition
to software interlocking and
the interlocking inherently
provided by the transfer
mechanism.
Multi-Tap Voltage Selector
Eaton’s industry-exclusive
Multi-Tap system voltage
selector allows our transfer
switch to be applied on most
system voltages just by proper
insertion of the selector
plug. Available in two
configurations: Worldwide
Multi-Tap with 600, 480, 415,
380, 240, 220 and 208 Vac,
single- and three-phase,
50 and 60 Hz taps. North
American Multi-Tap with
600, 480, 240, 208 and
120 Vac, single- and threephase, 60 Hz taps.
North American
Voltage Selector
North American multi-tap
transformer comes with 600,
480, 240, 208 and 120 Vac,
single- and three-phase, and
60 Hz taps, which are all field
selectable. Simply remove
the steel cover and move the
appropriate blue flag terminal
to the desired voltage. All
switches are shipped with
the blue flag in the 600V
position.

easy and complete isolation
of the control circuitry.
Maintenance can be
performed on the logic
independent from the power
sections and still allow the
user to manually transfer
power under full load
conditions.

Product Description
Application Description
Features, Benefits and Functions
Eaton’s Magnum transfer
switches are designed for a
variety of standby power
applications for critical and
noncritical loads. They
monitor both Source 1
(Normal) and Source 2
(Emergency) power sources.
In the event of a Source 1
power interruption, these
switches will automatically
transfer the load circuits to
the Source 2 power source.
Once Source 1 power source
has been restored, the
process is automatically
reversed.
The Magnum family of
transfer switches covers
applications ranging from 200
to 5000A through 600 Vac.
Some of the applications are:
automatic or non-automatic
configurations, open or
closed transition and standard
or rated suitable for use as
service entrance. They are
designed for applications
where total system
coordination must be
accomplished while achieving
a high level of Withstand,
Interrupting, and Closing
performance.

Unmatched Performance
and Versatility
The Eaton family of Magnum
transfer switches offers
unmatched performance,
versatility and value for
standby power applications.
At the heart of these designs
is the Magnum switch with
the following features:
Superior Main
Contact Structure
All Eaton Magnum Transfer
Switches meet or exceed
the standards set forth in
UL 1008 and UL 489 with
high withstand, totally
enclosed Magnum switches.
No other transfer switch
manufacturer has met the
rigid testing requirements
of this combination of
standards. Completely
enclosed contacts add a
measure of safety and
reliability. They also ensures
the integrity of the contact
assemblies and minimizes
the need for periodic
maintenance of the contacts,
reducing downtime and
maintenance time.
Ease of Coordination
and Application—
Short-Time Withstand
The use of electronic trips
has allowed performance
curve shaping to facilitate
proper system coordination.
The most significant is the
“short time” rated trip unit.

Fast, Powerful and Safe
Switching Mechanism
The mechanism utilizes a
high speed ≤ than 3-cycle
stored energy switching
mechanism. This mechanism
can be operated manually

These trip settings may be
set for what are considered
extremely high currents for
much longer durations than
the three-cycle withstand
test required under UL 1008.
To facilitate improved
coordination, Eaton Magnum
transfer switches have been
tested and are provided with
30-cycle, extended withstand
ratings.
www.eaton.com
Optional DigitripTM Magnum Trip Unit
Service Entrance
For service entrance and
other applications, Digitrip
solid-state trip units can be
integrated into the power
switching section. This
eliminates the need for
separate upstream protective
devices, saving cost and
space. Available with various
combinations of long, short
time, instantaneous, ground
fault protection and
communications.
16.4
Transfer Switches
Magnum-Based Design
Interlocking for Open
Transition Applications
The open transition type
Magnum Transfer Switches
feature both mechanical
(cable) and electrical
interlocking to prevent
paralleling of sources.
Ease of Maintenance
Keyed quick-disconnect plugs
are provided for easy and
complete isolation of the
control circuitry.
16

Maintenance can be
performed on the logic
independent from the power
sections and still allow the

Bypass Isolation Transfer Switch
Product Description
Application Description
Features, Benefits and Functions
A bypass isolation switch
utilizes loadbreak isolation
and bypass transfer power
contacts. Thus, should
voltage be lost on the line to
which the ATS is connected,
and should a manual bypass
be required to the other line,
this can be accomplished
safely and quickly as
described below. With
contactor designs utilizing
non-loadbreak isolation and
bypass switches, manual
bypass to the other line is
hindered by mechanical or
electrical safety interlocking.
The bypass isolation switch
is designed for applications
where maintenance,
inspection and testing
must be performed while
maintaining continuous
power to the load. This is
typically required in critical
life-support systems and
standby power situations
calling for safe system
maintenance with no power
disruptions. Such a design
allows for the quick removal
of the different switching
devices for inspection,
maintenance or replacement.
Eaton’s transfer switch is
a rugged, compact design
utilizing Magnum power
switches or Magnum power
circuit breakers to transfer
essential loads from one
power source to another.
Open transition switching
devices are interlocked to
prevent both switching
devices from being closed at
the same time. The versatile
design, in addition to standard
transfer functions, offers an
optional integral thermal
and short-circuit protection
in either or both switching
devices.
The switching devices
are in a compact vertical
arrangement. The logic
can be easily disconnected
from the switching device
without disturbing critical
connections. The enclosure
is free standing, and by
using the specially supplied
cleats, the switch is seismic
approved (Option 42). The
terminals are mounted in the
rear of the switch, permitting
rear, top, bottom or side
cable or bus bar entrance.
16
The switching devices have
a high withstand rating. The
high-speed, stored-energy
switching mechanism
guarantees a transfer time
of less than three cycles.

Standards and Certifications
16
Eaton transfer switch
equipment is listed for
application by UL and CSA.
In addition, Eaton ATSs are
listed in File E38116 by
Underwriters Laboratories
under Standard UL 1008. This
standard covers requirements
for ATSs intended for use in
ordinary locations to provide
for lighting and power as
follows:

Articles 517 and 700 in
the National Electrical
Code (NEC), American
National Standards
Institute/National Fire
Protection Association
(ANSI/NFPA) 70 and the
NFPA No. 76A and/or
B. In standby systems, in

C. In legally required standby

with Article 701 of the
NEC. Eaton ATSs are
available to meet NFPA
110 for emergency and
standby power systems,
and NFPA 99 for healthcare facilities when
ordered with the
appropriate options.
Since Eaton ATSs utilize
specially designed
switches and/or
switching devices as the
main power switching
contacts, these devices
must also be listed under
the additional UL
Standard 1066. UL
utilizes two basic types
of listing programs:

a. Label Service, and
b. Re-examination.
UL 1066 employs a
label service listing
program that requires
an extensive followup testing program
for listed devices.
Standard UL 1008 for
ATSs lists devices
under the reexamination program
that only requires a
continual physical reexamination of the
components used in
the product to ensure
consistency with the
originally submitted
device. Follow-up
testing IS NOT
required by UL 1008.
Representative
production samples
of switches and
switching devices
used in Eaton ATSs
are subjected to a
complete test
program identical to
the originally
submitted devices on
an ongoing periodic
basis per UL 1066. The
frequency of such a
re-submittal can be as
often as every quarter
for a low ampere
device.
Note: IBC seismic qualified.

Product Description
16
Electrical power generation
located at or near the point of
its consumption, commonly
referred to as distributed
generation, has seen
tremendous growth recently
due to factors such as limited
utility grid generation and
transmission capacity
combined with the onset of
utility deregulation. Strong
economic incentives now
exist for many users to
consider on-site selfgeneration for both improved
power reliability and energy
cost reduction. Additionally,
these opportunities have
spurred the development of
new and unique types of
generating and switching
technologies.
Eaton closed transition soft
load automatic transfer
switches are just such a
technology. Closed transition
soft load transfer switches
are an ideal solution for
power availability, energy
management and generatorset exercising applications.
Unlike traditional open
transition switches that
provide a break-before-make
operation, the closed
transition soft load switch
allows two power sources,
usually the utility and a
generator set, to be paralleled
indefinitely. This permits the
load, inductive or resistive, to
be gradually and seamlessly
transferred from one source
to another. All of this is
accomplished through the
make-before-break operation
of the switch with no power
interruption to the load.
Eaton closed transition soft
load switch utilizes an
integrated micro-processorbased power controller to
make active paralleling of two
power sources possible. It
manages the speed governor
and voltage regulator of the
generator set to bring the two
sources into synchronization.
This approach allows the
transfer switch to be applied
in soft load transfer
applications. In addition, it
can also be used as a peak
shaving switch helping
customers to reduce their
peak demand charges by
paralleling the generator set
with the utility source during
times of high electrical
demand.
Standard fixed drawout or
drawout bypass isolation
configurations are available
with or without an integral
service entrance rating. If a
switch with a service
entrance rating is used as
service entrance equipment,
the need for separate service
disconnects and overcurrent
protective devices is
eliminated.
Eaton closed transition soft
load automatic transfer
switches are available for
800 through 3200A, up to
600 Vac, 50 or 60 Hz
applications worldwide.
They are offered in both
indoor (NEMA 1) and outdoor
(NEMA 3R) free-standing
enclosures utilizing drawout
or fixed insulated case
Magnum DS switching
devices. The Magnum DS
switching device is a 100%
rated device with a 100 kA
interrupting capability at
600 Vac.

Application Description
Power reliability and power
costs are two issues of
strategic importance in
almost all industry segments.
Businesses have critical
processes that cannot
tolerate a shutdown, while
an extended failure in
many cases could cause
unrecoverable losses. In
addition, significant changes
in the utility industry have
created on-site generation
opportunities for customers
to address their power
reliability and energy cost
concerns. This type of on-site
power generation at or near
the point of consumption is
known as distributed
generation. Market studies
estimate that over 40% of
generation capacity added
in the United States alone
over the next 10 years will be
distributed. A key enabler
of these on-site generation
systems and reliable power
in general is often a closed
transition soft load transfer
switch.
Typical applications for Eaton
closed transition soft load
automatic transfer switches
include industrial processes,
data centers and critical care
facilities. Any location with
critical loads where the
absence of power could
result in lost revenue,
production time or personal
injury should make this
equipment a prime
consideration.

Features, Benefits and Functions
Consider Several
Specific Applications
●
A facility with emergency
or critical power systems
wanting to test their
generator sets without a
power interruption
●
Any industrial, institutional
or commercial business
seeking ways to lower
energy costs by reducing
demand charges, which
can represent over 50% of
an electrical bill
●
Energy service companies
interested in offering
performance-based
solutions to their
customer base
●
Electrical power providers
interested in offering
power reliability solutions
to their customer base in
return for long-term
electrical contracts
The Eaton closed transition
soft load automatic transfer
switch can be applied in new
installations or as a retrofit
to replace an existing open
transition transfer switch. A
number of application issues
should be reviewed. First,
since most generator sets
run on diesel fuel, there are
exhaust emission concerns
to consider. In some markets,
the Environmental Protection
Agency (EPA) limits the
number of hours annually
that a generator set can be
operated. Methods to deal
with such restrictions, should
they present a problem, are
the use of natural gas or
dual fuel (natural gas/diesel
mixture) types of generator
sets. A second issue relates
to electrical utility
interconnection standards.
Many utility companies
require multiple levels of
protective relaying when
a user wishes to parallel to
the utility grid. The cost of
meeting some of these
specifications can be high.
These issues should be
discussed when peak shaving
is being considered.
Sequence of Operations
Automatic Mode
Operation—Transfer
Switch Loss of
Normal Power
The system will continuously
monitor the condition of the
normal power supply. When
the voltage or frequency of
the normal source is sensed
outside the user-adjustable
set points, and after an
adjustable time delay to
override momentary dips and/
or outages, a contact shall
close to initiate a starting of
the emergency or standby
source. Transfer to the
alternate source shall take
place upon attainment of
adjustable pickup voltage and
frequency of the alternate
source.
Return of Normal Power—
Breaker Open Transition
Logic Selected
When normal source has
been restored and is within
the preselected ranges for
voltage and frequency and
after a time delay to ensure
the integrity of the normal
power source, the load shall
be transferred back to normal
source in a break-beforemake transfer scheme. The
generator set will continue to
run for a user-adjustable time
to allow the generator set to
run unloaded for cool down,
after which the engine will be
shut down. Upon completion,
the system will then be ready
for automatic operation.
Return of Normal Power—
Breaker Closed Transition
Logic Selected
When the normal source has
been restored and is within
the preselected ranges for
voltage and frequency, and
after an adjustable time delay
to ensure the integrity of the
normal source, the load shall
be transferred back to the
normal source in a makebefore-brake transfer
scheme.

On completion of the time
delay, the generator-set bus
will automatically synchronize
with the utility service across
the Source 1 (normal)
breaker. When the two
systems are synchronized,
the Source 1 (normal) breaker
will close and the Source 2
(emergency) breaker will
open. The generator set will
continue to run for
a user-adjustable time to
allow the generator set to run
unloaded for cool down, after
which the engine will be shut
down. Upon completion, the
system will then be ready for
automatic operation.
Return of Normal—
Breaker Interchange
(Soft Load) Logic Selected
When the normal source has
been restored and is within
the preselected ranges for
voltage and frequency, and
after an adjustable time delay
to ensure the integrity of the
normal source, the load shall
be transferred back to the
normal source in a makebefore-brake transfer
scheme. On completion of
the time delay, the generatorset bus will automatically
synchronize with the utility
service across the Source 1
(normal) breaker. When
the two systems are
synchronized, the Source 1
(normal) breaker will close
and the generator set will
gradually transfer all loads
to the utility.
On completion of the load
transfer sequence the
Source 2 (emergency)
breaker will open. The
generator set will continue
to run for a user-adjustable
time to allow the generator
set to run unloaded for cool
down, after which the engine
will be shut down. Upon
completion, the system
will then be ready for
automatic operation.
Transfer Switches
Magnum-Based Designs
Peak Shaving
The closed transition soft
load transfer switch can
be factory configured to
automatically parallel to the
utility. In this operation mode,
the switch will be paralleled
with the utility when the
user-adjustable load power
level is exceeded for the
predetermined amount
of time.
Returning either the Auto/
Test selector switch to
“Auto” position or the Test
Mode selector switch to
“Off” position will cause the
system to return to normal
power as described in
“Return Of Normal Power—
Breaker Open Transition
Logic Selected.”
Test Mode Operation
Engine Run Test Mode
To perform an engine run
test, first place the System
Test switch in the “Run”
position. Next place the
Auto/Test switch in the “Test”
position. The engine start
contact will close, the engine
will start and the generator
will produce nominal voltage
and frequency.
Note: This operation is carried out
when the controller’s breaker logic
is changed to closed transfer via
ATC-5000 Input 64.
Neither Source 1 nor Source
2 breaker will be operated.
Returning either the System
Test to “Off” position or
Auto/Test switch to “Auto”
position will remove the
“Engine Start” command.
The engine will shut down.
Transfer Test Mode
(Open Transfer)
Note: This operation is carried
out when the controller’s breaker
logic is programmed for open
transition via ATC-5000 Input 64.
To perform an open transition
test, first place the Test
Mode selector switch in the
“Mode 1” position, followed
by placing the System Test
switch in “Test” position,
followed by placing Auto/Test
selector switch in the “Test”
position. After an adjustable
time delay, the generator
will start. After the nominal
voltage and frequency are
reached, the Source 1
(normal) breaker will open
and the Source 2 (emergency)
breaker will close on the
dead bus.
Transfer Test Mode
(Closed Transition)
To perform a closed transition
test, first place the Test
Mode selector switch in the
“Mode 2” position, followed
by placing the System Test
switch in “Test” position,
followed by placing the Auto/
Test selector switch in the
“Test” position. After an
adjustable time delay, the
generator will start. After the
nominal voltage and frequency
are reached, the generator
bus will be synchronized to
the utility across the Source 2
(emergency) breaker. When
the two sources are
synchronized the Source 2
(emergency) breaker closes
and then Source 1 (normal)
breaker opens.
Returning either the Auto/
Test selector switch to
“Auto” position or the
System Test selector switch
to “Off” position will cause
the system to return to
normal power as described in
“Return Of Normal Power—
Breaker Closed Transition
Logic Selected.”
Transfer Test Mode
(Interchange—
Soft Load Transition)
Note: This operation is
carried out when the controller’s
breaker logic is programmed for
interchange (soft load transition).
To perform an interchange
(soft load transition) test, first
place the Test Mode selector
switch in the “Mode 1”
position, followed by placing
the System Test switch in
“Test” position, followed by
placing the Auto/Test selector
switch in the “Test” position.
After an adjustable time delay,
the generator will start. After
the nominal voltage and
frequency are reached, the
generator bus will be
synchronized to the utility
across the Source 2
(emergency) breaker.
When the two sources are
synchronized, the Source 2
(emergency) breaker is
closed, and the generator
gradually assumes all load.
On completion of the load
transfer sequence, the Source
1 (normal) breaker will open.
Returning either the Auto/
Test selector switch to
“Auto” position or the
System Test selector switch
to “Off” position will cause
the system to return to
normal power as described
in “Return of Normal
Power (Switch in Closed
Transition Mode).”
16.4
Paralleling Test Mode
(Baseload)
16
Note: This operation is carried
out when the controller’s Breaker
Logic is changed to Parallel via
ATC-5000 Input 64 and the
Baseload operation is selected.
To perform a paralleling test
in a base load mode, first
place the Test Mode selector
switch in the “Mode 2”
position, followed by placing
the System Test switch in
“Test” position, followed by
placing the Auto/Test selector
switch in the “Test” position.
After an adjustable time
delay, the generator will start.
After the nominal voltage and
frequency are reached, the
generator bus will be
synchronized to the utility
across the Source 2
(emergency) breaker.
When the two sources are
synchronized, the Source 2
(emergency) breaker is
closed and the generator
gradually assumes load up
to the user-programmable
power level and then
continuously maintains its
power output.
Returning either the Auto/
Test selector switch to
“Auto” position or the
System Test selector switch
to “Off” position will cause

the engine will be shut down.
Upon completion, the system
will then be ready for
automatic operation.

Base Components
Enclosure
The rugged steel switch
enclosure is supplied with
four door hinges, regardless
of enclosure size, to ensure
proper support of the door
and door-mounted devices.
The hinges have removable
hinge pins to facilitate door
removal. The doors are
supplied as standard with
thumbscrew and padlock
latches. Cable entry holes are
the customer’s responsibility.
Power Cables
Power cables are to be
connected to solderless
screw-type lugs located on
the transfer switch switching
devices. Refer to the
separate customer wiring
diagrams supplied with the
transfer switch equipment
for power termination. Verify
that the lugs supplied will
accommodate the power
cables being used. Also verify
that the cables comply with
local electrical codes.
Standard transfer switch
equipment, as supplied
from the factory, will
accommodate the wire
sizes shown in table below.
The door is used to mount a
variety of lights, switches and
pushbuttons, depending
upon the options required for
a particular switch. All switch
doors are supplied with a
heavy-duty plastic accessory
panel in place, whether or not
external devices are required.
When lights, pushbuttons or
switches are required, they
are normally mounted in the
plastic door-mounted panel.

Transfer switch enclosures
and some internal steel
mounting plates, such
as the transformer panel
mounting plate, go through
a pretreatment cleaning
system prior to painting
to ensure a durable finish.
Should the enclosure
become scratched and in
need of touch-up paint, use
ANSI 61. All remaining steel
is galvanized.

The standard switch
enclosure is NEMA Type 1
for general indoor use. See

Technical Data and Specifications
System
Standards
Eaton Soft Load ATSs are
listed in File E38116 by
Underwriters Laboratories,
under Standard UL 1008. This
standard covers requirements
for ATSs intended for use in
ordinary locations to provide
for lighting and power as
follows:
A. In emergency systems,
in accordance with
articles 517 and 700 in the
National Electrical Code
(NEC), American National
Standards Institute/
National Fire Protection
Association (ANSI/NFPA)
70 and the NFPA No.
76A.
B. In stand-by systems, in
accordance with article
702 of the NEC.
16
16
C. In legally required
standby systems in
accordance with article
701 of the NEC.
Eaton ATSs are available
to meet NFPA 110 for
emergency and standby
power systems, and
NFPA 99 for health-care
facilities when ordered with
the appropriate options.
Since Eaton ATSs utilize
specially designed switches
and/or switching devices as
the main power switching
contacts, these devices must
also be listed under the
additional UL Standard 1066.
UL utilizes two basic types of
listing programs: a) Label
Service and b) Reexamination. UL 1066
employs a label service listing
program that requires an
extensive follow-up testing
program for listed devices.
Standard UL 1008 for ATSs
lists devices under the reexamination program that
only requires a continual
physical re-examination of
the components used in the
product to ensure
consistency with the
originally submitted device.
Follow-up testing IS NOT
required by UL 1008.
Representative production
samples of switches and
switching devices used in
Eaton ATSs are subjected
to a complete test program
identical to the originally
submitted devices on an
ongoing periodic basis per
UL 1066.
The frequency of such a
resubmittal can be as often
as every quarter for a low
ampere device.

Product Description
Application Description
Features, Benefits and Functions
The ATC-100 Controller is a
comprehensive, multifunction,
microprocessor-based ATS
controller. It is a compact,
self-contained, panelmounted device designed to
replace traditional relay and
solid-state logic panels.
The ATC-100 Controller
provides both fixed and
jumper-selectable settings
to allow for a range of
applications. It operates from
all system voltages between
120 and 480 Vac, singlephase and three-phase, at 50
or 60 Hz. In addition, a period
of no control power operation
is provided. The ATC-100
Controller monitors the
condition of the three-phase
line-to-line voltage and
frequency of both the
utility and generator power
sources. It can also be set
up for single-phase operation.
The ATC-100 controller
provides the necessary
intelligence to ensure that
the transfer switch operates
properly through a series of
sensing and timing functions.

Eaton’s ATC-600 is a
microprocessor-based logic
controller to be used with
transfer switches. This
device is door-mounted
and provides the operator
with an at-a-glance overview
of switch status and
parameters, as well as
key diagnostic data. Realtime values for volts and
frequency can be viewed
via the front panel LED
display, along with an
indication of the power
source currently in use.
The ATC-600 continuously
monitors either single-phase
or three-phase voltages for
Source 1, Source 2 and the
load. When the Source 1
voltage or frequency is
detected to be below the
customer-programmed set
points, transfer to Source 2 is
initiated. When the Source 2
voltage and frequency are
detected to be within the
programmed parameters,
the transfer occurs.
While the load is connected
to Source 2, the ATC-600
continues to monitor
Source 1. As soon as the
Source 1 voltage and
frequency return to within
the programmed limits, and
after a programmed time
delay, a retransfer back to
Source 1 is initiated.
The ATC-600 uses
microprocessor technology
to provide the operator with
a vast array of selections.
Depending on the application,
the user can “customize”
the ATC-600 to meet the
particular application. A
summary of several key
selections is listed in table
on Page 79.
Application Description
Standards and Certifications
The ATC-600 is equipped to
display history information
either via the front panel or
over PowerNet™. Source 1
and Source 2 run time,
available time, and connect
time are available, as well as
Load energized time, number
of transfers, and the date,
time and reason for the last
16 transfers.
●
For communications
capability, the ATC-600 can
be equipped with a PONI card
that will allow the user to
communicate with the unit
via Series III software. All
settings for purchased
options can be set from
the faceplate of the unit or
downloaded over PowerNet.
Series III software allows
for charting of key historical
data, as well as providing the
capability to monitor and
control the transfer switch
from a remote location.
For further information on
PowerNet products and
software, see Section 26.

ATC-800 Transition Controller
Product Description
The ATC-800 is a
programmable,
microprocessor-based
monitoring device designed
for use in Eaton closed
transition transfer switches
and for open transition
contactor-based designs. By
using Eaton’s ATC-800, the
user may avoid intentional
interruption of power when
both sources of power are
available. This make-beforebreak mode of operation is
useful during testing of the
engine generator under load
and where a predetermined
transfer to the generator is
desired. Source paralleling
duration is limited to less
than100 msec.
Passive Closed Transition
The closed transition mode
of operation requires that
both power sources be
synchronized in voltage,
frequency and phase angle
within prescribed limits.
Eaton’s ATC-800 uses a
technique that involves
waiting for synchronization
of the two sources without
actively controlling the
generator’s voltage or
frequency. The mode of
operation is anticipatory in that
the switch close command is
initiated before the sources
are exactly in phase. Utilizing
the phase angle and
16
Application Description
frequency difference between
the two sources, a calculation
is made to predict when both
sources would be in phase.
The response time of the
switch is then factored in to
determine when the switch
close signal should be given to
ensure optimal closure of the
two sources in phase.
●
Eaton’s closed transition
ATC-800 must be selected
with one of three feature
sets: 47C, 47D or 47E (47D,
47F, 47G on contactor-based
designs. The difference
between these three feature
sets is the action taken by the
closed transition ATC-800 if it
is determined that the two
sources will not achieve
synchronization. If feature set
47C is selected, failure to
synchronize results in the
switch reverting to an Open
Transition mode of operation
with low voltage decay. If
feature set 47E is selected,
then failure to synchronize
results in the switch reverting
to time delay neutral.
However, if feature set 47D is
selected, failure to synchronize
will result in the ATC-800
refusing to transfer to Source 2
and an alarm signal being
activated. In neither case will
there be a paralleling of
sources if synchronization is
not achieved.
●
●
The generator used with
a closed transition transfer
switch must be equipped
with an isynchronous
governor
When paralleling sources,
fault current contributions
from both sources should
be considered in the
system design
Closed Transition (makebefore-break) technology
causes paralleling with the
Source 1. It is the user’s
responsibility to comply
with any requirements
regarding protective
relaying. Protective
relaying is not supplied
with the standard transfer
switch, but is available as
an option

transfer switch front panel.
Data access and programming
operations are performed
using the ATC-800 Transfer’s
touch-sensitive function
buttons in conjunction with
an easy-to-read, illuminated,
alphanumeric LED display.
Both the function buttons
and the display window are
part of the device’s front
panel. A built-in Help button
provides user assistance in
the form of message displays.
The ATC-800 is
communications ready
and compatible with all
Eaton IQ devices as well as
the Eaton PowerNet systemwide supervisory and control
software. This permits
monitoring and control of
several transfer switches,
locally or remotely, from a
single point.

ATC-800 Programming
Button Functions
Three buttons provide easy
access to all commonly used
ATC-800 functions.
When the preferred source is
connected and the ATS is
operating normally, the
automatic indicator light will be
flashing and the display
window will be blank.
Using the Display Select
button, the operator can step
through each of the six
display families:

Set points
Initial Programming
Factory programming will
load all customer-specified
functions and presets. At the
customer’s request, Eaton
will add, delete or adjust
optional features.
Customer Programming
Customers may reprogram
set points and other
parameters to match
their application, using the
program switch located on
the rear of the unit. Once the
programming mode has been
activated and the program
light is flashing, the user may
access set point settings by
pressing the Display Select
button until the set points
LED is illuminated. Values
for individual set points may
then be altered by pressing the
Increase or Decrease buttons.
Once a parameter has been
reset, the user advances to
the next set point by pressing
the Step button.
While the ATC-800 is in the
program mode, the device
continues to operate in
accordance with the
previously programmed
set points and parameters.
The unit is never offline,
and preset values do not
change until programming
has been completed.
Once reprogramming is
complete, the user may
return the program switch to
the run position. At this point,
all new values are stored in
the ATC-800 non-volatile
memory, and the unit returns
to Automatic mode.
Note: Stepping through the
various display modes does not
alter preset values or otherwise
affect operation of the ATS.
Once the desired display
family is selected, the user
may press the Step button
to cycle through specific
parameters or metered
values shown in the
display window.

Definitions
Closed transition: Closed
transition is a feature that will
temporarily parallel two live
sources in a make-beforebreak scheme when
performing a transfer. The
ATC-800 will close the
switching devices for both
sources, paralleling both
sources, for a maximum time
of 100 milliseconds after the
sources are synchronized.
Open transition/in-phase
monitor: In-phase monitor
is a feature that will allow
a transfer between two
sources only when the phase
difference between the two
sources is near zero. This is
an open transition transfer
that prevents inrush currents
from exceeding normal
starting currents in the
case where motor loads
are being transferred.
Open transition/delayed
with load voltage decay:
Load voltage decay transfer is
a feature that, after opening
the switch for the original
source, holds in the neutral
position until the voltage on
the load is less than 30% of
rated voltage. This is an open
transition that prevents inrush
currents from exceeding
normal starting currents in
the case where motor loads
are being transferred.

Feature Set 47C Closed/InPhase/Load Voltage Decay
ATC-800 controllers
equipped with Feature Set
47C execute the following
sequence of operations
upon receipt of a request
for transfer: the controller
waits (for a preselected time
frame) for synchronization
of voltage and frequency. If
achieved, a closed transition
transfer occurs. Failure to
synchronize results in the
controller defaulting to
an in-phase monitor, open
transition mode of operation.
If the two sources fail
to achieve frequency
synchronization within the
user-selectable range, the
controller defaults to an
open transition using
a load voltage decay
delayed transition.

Transfer Switches
ATC Controllers
In-Phase Transfer
Feature Set 47D
Closed Only
ATC-800 controllers
equipped with Feature Set
47D only transfer to an
alternate source when both
sources are synchronized.
For synchronization to occur,
both voltage and frequency
differentials must fall within
the user-selectable ranges. If
synchronization does not
occur (within a preselected
amount of time), the
controller will maintain load
connection to the current
power source and initiate
an alarm.
Closed Transition
With Default to In-Phase
Transition With Default
to Time Delay Neutral
Provides a closed transition
transfer as the primary
transfer mode. In the event
Source 1 and Source 2 fail
to synchronize within the
permitted voltage difference,
frequency difference, phase
angle difference and time,
then the controller defaults
to the In-phase transition
with default to time delay
neutral operation as
described in Features 32D
and 32A. Adjustable

0.0–0.3 Hz. Adjustable
voltage difference

ATC-800 controllers equipped
with Feature Set 47F will
perform a closed transition
when both sources are
synchronized in frequency,
phase and voltage. Failure to
synchronize will result in an
open transition Time Delay
Load Voltage Decay transfer.
Time Delay Load Voltage
Decay uses the load voltage
measurements to sense back
EMF that is generated when
the transfer switch is in the
Neutral position. It provides
a delay in transfer in either
direction if an unacceptable
level is sensed as established
by a customer programmed
level. The transfer will not
take place until the back EMF
decays below the acceptable
programmed level. This
feature has a separate setting
of enabling or disabling the
operation. If disabled, the
transfer switch will not delay
in the Neutral position and
will transfer between the
sources as fast as possible.
This feature is not available
with the Time Delay Neutral
Optional Feature 32A,
16
16
16
Neutral provides a time delay
in the transfer switch neutral
position when both sources
are open. This delay takes
place when the load is
transferred in either direction
to prevent excessive in-rush
currents due to out-of-phase
switching of large motor
loads.

Transfer Switches
Standard and Optional Features
16.6
Feature Description
Timers
1. Time Delay Normal to
Emergency (TDNE)
Provides a time delay to allow
for the generator to warm up
before transferring the load
to the emergency source.
Timing begins only after the
Emergency Source becomes
available and is deemed good
based on the programmable
voltage and frequency set
points in the controller.
2. Time Delay Engine
Start (TDES)
Provides a time delay before
initiating the generator start
cycle. This is to account for
momentary power outages
or voltage fluctuations of the
normal source. Provides a
Form C contact to the
generator starter circuit.
3. Time Delay Emergency to
Normal (TDEN)
Provides a time delay of the
retransfer operation to permit
stabilization of the normal
source. Timing begins only
after the normal source
becomes available and is
deemed good based on the
programmable voltage and
frequency set points in the
controller. This function is failsafe protected.
16
Plant Exerciser
16
4. Time Delay Engine
Cooldown (TDEC)
Provides a time delay before
initiating the generator stop
cycle after the retransfer
operation. This allows the
generator to cool down by
running unloaded. Timing
begins on completion of the
retransfer cycle.
23A. Plant Exerciser
With Fail-Safe
Provides a means for
automatic testing of the
engine generator set or
standby power system. All
programmed time delays
in the controller will be
performed during plant
exerciser operations.
23K. Plant Exerciser
With Fail-Safe
Provides a means for
automatic testing of the
engine generator set or
standby power system. All
programmed time delays
in the controller will be
performed during plant
exerciser operations.
7. Time Delay Emergency
Fail (TDEF)
Provides a time delay that
prevents a connected
emergency source from
being declared “unavailable”
based on the customer’s
set points. This is to account
for momentary generator
fluctuations. If the Source 2
remains in a failed state, then
0.5 second after the TDEF
timer expires the transfer
switch will proceed with the
programmed sequence for
retransfer if Source 1 is
available. This time delay is
only implemented when
Source 2 is a generator.
Programmable set points for
test intervals are start time,
either disabled, daily, 7, 14
or 28 days.
Programmable set points for
test intervals are start time,
either disabled, daily, 7, 14 or
28 days, engine test time.
15-minute fixed engine
test time.
Test may be performed with
or without load transfer. Test
may be manually cancelled
during the operation. This
function is fail-safe protected.
Note: This feature is also enabled
when large loads cause generator
output to drop below customer
set points.

transition transfer switch
may prevent or reduce inrush
currents due to out-of-phase
switching of inductive loads.
Transfer Switches
Standard and Optional Features
16.6

32A. Time Delay Neutral
Provides a time delay in the
neutral position during the
transfer and retransfer
operations during which both
Source 1 and Source 2 are
disconnected from the load
circuit. This allows inductive
loads time to reach a safe
voltage and eliminate back
EMF. The time delay is
programmable and is the
same for both transfer and
retransfer operations. This is a
passive feature that requires
the consulting engineer/
installer to determine the
settings based on how the
user will operate the facility.
Adjustable 0–120 seconds.
32B. Load Voltage Decay
Provides load voltage
measurement to sense back
EMF that is generated when
the transfer switch is the
neutral position. It provides
a delay in transfer in either
direction if an unacceptable
level is sensed as established
by a programmed set point.
This is an active feature that
adapts to how the facility is
operating in order to minimize
neutral position wait time,
but ensure safety. Adjustable
2–30% of nominal voltage.
32C. In-Phase Transition With
Default to Load Voltage Decay
Provides in-phase transition,
which is a feature that will
permit a transfer or retransfer
between two available
sources that have a phase
angle difference near zero.
The in-phase transition
feature includes permissible
frequency difference and
synchronization time set
points. In the event Source 1
and Source 2 fail to
synchronize within the
permitted frequency
difference and time, then
the controller defaults to the
load voltage decay operation
as described in Feature 32B.
Adjustable frequency
difference 0.0–3.0 Hz.
Adjustable synchronization
time allowance 1–60 minutes.
32D. In-Phase Transition With
Default to Time Delay Neutral
Provides in-phase transition,
which is a feature that will
permit a transfer or retransfer
only between two available
sources that have a phase
angle difference near zero.
The in-phase transition feature
includes permissible
frequency difference and
synchronization time set
points. In the event Source 1
and Source 2 fail to
synchronize within the
permitted frequency
difference and time, then the
controller defaults to the time
delay neutral operation as
described in Feature 32A.
Adjustable frequency
difference 0.0–3.0 Hz.
Adjustable synchronization
time allowance 1–60 minutes.
32F. In-Phase Transition
Provides in-phase transition,
this feature will permit a
transfer or retransfer
between two available
sources that have a phase
angle difference of 8 degrees
or less. The in-phase transition
feature includes permissible
frequency difference and
synchronization time set
points. In the event Source 1
and Source 2 fail to
synchronize within the
permitted frequency
difference and time, the
Alarm relay will energize
and “Failed to Sync” will be
displayed on Line 1 of the
controller. After resetting
the alarm, another in-phase
transition may be attempted
or a non-synchronized transfer
may be initiated by failing
the connected source. The
adjustable frequency
difference is 0.0 to 3.0 Hz.
If the synchronization does
not occur within a specified
amount of time, the Alarm
relay will energize and the
failure will be logged into
the transfer history as either
“Sync Fail - Freq” or “Sync
Fail - Phase” depending on
whether the frequency
difference or the phase
difference was excessive.
32G. Time Delay Neutral
This feature provides a time
delay in the neutral position
during the transfer and
retransfer operations during
which both the utility source
and the generator source are
disconnected from the load
circuit. TDN cannot be
implemented on a transfer
switch using a 2-position
contactor.
Jumper selectable at
disable (0 seconds) or
enable (2 seconds).
47. Transfer Modes for Closed
Transition Transfer Switches
Provides available transition
transfer modes for a closed
transition transfer switch.
Closed transition is a “make
before break” transfer and
retransfer scheme that will
parallel (a maximum of 100
ms) Source 1 and Source 2
providing a seamless transfer
when both sources are
available. The closed
transition feature includes
permissible voltage difference
frequency difference and
synchronization time
allowance set points. The
phase angle difference
between the two sources
must be near zero for a
permitted transfer. These are
all programmable set points
in the controller.
47C. Closed Transition
With Default to In-Phase
Transition With Default to
Load Voltage Decay
Provides a closed transition
transfer as the primary
transfer mode. In the event
Source 1 and Source 2 fail
to synchronize within the
permitted voltage difference,
frequency difference, phase
angle difference and time,
then the controller defaults to
the in-phase transition with
default to load voltage decay
operations as described in
Features 32C and 32B.
Adjustable frequency
difference 0.0–0.3 Hz.
Adjustable voltage difference
1–5% volts. Adjustable
synchronization time
allowance 1–60 minutes.
Distribution Products Catalog CA08101001E—October 2010
47D. Closed Transition
Provides a closed transition
transfer as the primary
transfer mode. Only under
a fail-safe condition (i.e., loss
of the connected source) will
the controller transfer to the
alternate source using the
load voltage decay operation
as described in Feature 32B.
Adjustable frequency
difference 0.0–0.3 Hz.
Adjustable voltage
difference 1–5% V.
47E. Closed Transition
With Default to In-Phase
Transition With Default to
Time Delay Neutral
Provides a closed transition
transfer as the primary
transfer mode. In the event
Source 1 and Source 2 fail to
synchronize within the
permitted voltage difference,
frequency difference, phase
angle difference and time,
then the controller defaults to
the in-phase transition with
default to time delay neutral
operation as described in
Features 32D and 32A and .
Adjustable frequency
difference 0.0–0.3 Hz.
Adjustable voltage difference

load connection from the
secondary to primary source.
Source 1—is the primary
source or normal source or
normal power source or
normal. (Except when Source
2 has been designated the
“Preferred Source.”)
Source 2—is the secondary
source or emergency source
or emergency power source
or emergency or standby or
backup source. (Except
when Source 2 has been
designated the “Preferred
Source.”)
Source 1—Failed or fails—
Source 1 is defined as “failed”
when it is outside of its
undervoltage or overvoltage
or underfrequency or
overfrequency (if applicable)
set point ranges for the
nominal voltage and
frequency setting.
Source 2—Failed or fails—
Source 2 is defined as
“failed” when it is outside
of its undervoltage or
overvoltage or underfrequency or overfrequency
(if applicable) set point ranges
