3RT10 contactors, 3-pole, 3 ... 250 kW
■ Overview
3RT10 contactors, 3-pole, sizes S00 to S3, up to 45 kW
AC and DC operation
IEC 60947, EN 60947 (VDE 0660)
The 3RT1 contactors are climate-proof. They are finger-safe
according to EN 50274.
3
The 3RT1 contactors are available with screw terminals or with
Cage Clamp terminals.
Size S00 contactors have an auxiliary contact integrated in the
basic unit. The basic units of sizes S0 to S3 contain only the main
circuits.
All basic units can be extended with auxiliary switch blocks.
For size S0 and higher, complete units with 2 NO + 2 NC are
available (connection designation according to EN 50012). The
auxiliary switch block can be removed (for more information see
LV 1 T).
In addition, complete units with permanently mounted auxiliary
switch block (2 NO + 2 NC according to EN 50012) are offered
for sizes S00 and S0. These versions are built according to
special Swiss regulations "SUVA" and are distinguished
externally by a red identification plate.
The plug-in direction of the diodes and diode assemblies is
specified by coding.
Exceptions:
3RT19 26-1T.00 and
3RT19 36-1T.00; the plug-in direction is indicated here with "+"
and "-".
Coupling relays are supplied either without overvoltage
damping or with a varistor or diode connected as standard,
according to the version.
Note:
The OFF-delay times of the NO contacts and the ON-delay times
of the NC contacts increase if the contactor coils are damped
against voltage peaks (noise suppression diode 6 to 10 times;
diode assemblies 2 to 6 times, varistor +2 to 5 ms).
3RT10 contactors, 3-pole, sizes S6 to S12,
> 45 to 250 kW
• 3RT10, contactors for switching motors,
• 3RT12, vacuum contactors for switching motors,
• 3RT14, contactors for AC-1 applications.
Operating mechanism types
The size S3 contactors have removable box terminals for the
main conductor connections. This permits connection of ring
terminal lugs or busbars.
Two types of solenoid operation are available:
• Conventional operating mechanism
• Solid-state operating mechanism (with 3 performance levels)
Contact reliability
UC operation
If voltages ˆ 110 V and currents ˆ 100 mA are to be switched,
the auxiliary contacts of the 3RT1 contactor or 3RH11 contactor
relay should be used as they guarantee a high level of contact
reliability.
The contactors can be operated with AC (40 to 60 Hz) as well as
with DC.
These auxiliary contacts are suitable for electronic circuits with
currents ˜ 1 mA at a voltage of 17 V.
For simple coil replacement, e.g. if the application is replaced,
the magnetic coil can be pulled out upwards after the release
mechanism has been actuated and can be replaced by any
other coil of the same size.
Short circuit protection of the contactors
For more information about short circuit protection of contactors
without overload relay, see Technical Specifications. For more
informaiton about short circuit protection of the contactors with
overload relay, see "Overload Relays". When installing fuseless
motor feeders, the combinations of circuit-breakers and
contactors described under "Fuseless Load Feeders" must be
used.
Motor protection
3RU11 thermal overload relays or 3RB20 solid-state overload
relays can be fitted to the 3RT1 contactors for protection against
overload. The overload relays must be ordered separately.
Overvoltage damping
3RT1 contactors can be retrofitted with RC elements, varistors,
diodes or diode assemblies (assembly of diode and Zener diode
for short tripping times) for supressing opening surges in the
coil.
The surge suppressors are plugged onto the front of size S00
contactors. Space is provided for them next to a snap-on
auxiliary switch block.
For size S0 to S3 contactors, varistors and RC elements can be
snapped on either on the top or directly below the coil
connections. Diode assemblies are available in 2 different
versions on account of their polarity. Depending on the
application they can be connected either only at the bottom
(assembly with circuit-breaker) or only at the top (assembly with
overload relay).

Contactors with conventional operating mechanism
Version 3RT1...-.A:
The magnetic coil is switched directly on and off with the control
supply voltage Us by way of terminals A1/A2.
Multi-voltage range for the control supply voltage Us:
A single coil covers several control supply voltages of similar
ranges which are used worldwide, e.g. UC 110-115-120-127 V
or UC 220-230-240 V.
In addition, allowance is also made for a coil operating range of
0.8 times the lower (Us min) and 1.1 times the upper (Us max)
rated control supply voltage within which the contactor switches
reliably and no thermal overloading occurs.

Indication of remaining lifetime (RLT)
Main contactor contacts are working parts which must be
replaced in good time when the end of their service life has been
reached. The degree of contact erosion and thus the electrical
endurance (= number of operating cycles) depends on the
loading, utilization category, duty type, etc. Routine
checks/visual inspections by the service personnel are needed
in order to monitor the state of the main contacts. The "remaining
lifetime indication" function takes over this task. It does not count
the number of operating cycles – which does not provide
information about contact erosion – but instead electronically
identifies, evaluates and stores the actual progress of erosion of
each one of the three main contacts, and outputs a warning
when specified limits are reached. The stored data are not lost
even if the control supply voltage for A1/A2 fails. After
replacement of the main contacts, measurement the remaining
lifetime must be reset using the "RESET" button (hold down
RESET button for about 2 seconds using a pen or similar tool).

The magnetic coil is supplied selectively with the power required
for reliable switching and holding by series-connected control
electronics.
• Wide voltage range for the control supply voltage Us:
Compared with the conventional operating mechanism, the
solid-state operating mechanism covers an even broader
range of control supply voltages used worldwide within one
coil variant. For example, the coil for UC 200 to 277 V
(Us min to Us max) covers the voltages 200-208-220-230-240254-277 V used worldwide.
• Extended operating range 0.7 to 1.25 x Us:
The wide range for the rated control supply voltage and the
additionally allowed coil operating range of 0.8 x Us min to
1.1 x Us max results in an extended coil operating range of at
least 0.7 to 1.25 x Us, within which the contactors will operate
reliably, for the most common control supply voltages of 24,
110 and 230 V.
• Bridging temporary voltage dips:
Control voltage failures dipping to 0 V (at A1/A2) are bridged
for up to approx. 25 ms to avoid unintentional tripping.
• Defined ON and OFF thresholds:
For voltages of ˜ 0.8 x Us min and higher the electronics will
reliably switch the contactor ON, and as of ˆ 0.5 x Us min it is
reliably switched off. The differential travel in the switching
thresholds prevents the main contacts from chattering as well
as increased wear or welding when operated in weak,
unstable networks. This also prevents thermal overloading of
the contactor coil if the voltage applied is too low (contactor
does not close properly and is continuously operated with
overexcitation).
• Low control power consumption when closing and in the
closed state.
Advantages:
• Signaling through relay contact or AS-i when remaining
lifetime is 20 %, i.e. contact material wear is 80 %
• Additional visual indication of various levels of erosion by
means of LEDs on the laterally mounted solid-state module
when remaining lifetime is 60 % (green), 40 % (orange) and
20 % (red)
• Conventional control by applying the control supply voltage at
A1/A2 through a switching contact.
Note:
Slide switch must be in "PLC OFF" position
(= factory setting).

■ Overview
• 3RT12 vacuum contactors for switching motors
Withdrawable coils
Operating mechanism types
For simple coil replacement, e.g. if the application is replaced,
the magnetic coil can be pulled out upwards after the release
mechanism has been actuated and can be replaced by any
other coil of the same size.
Two types of solenoid operation are available:
• Conventional operating mechanism, version 3RT12 ..-.A
• Solid-state operating mechanism, version 3RT12 ..-.N

UC operation
The contactors can be operated with AC (40 to 60 Hz) as well as
with DC.
Auxiliary contact complement
The contactors can be fitted with up to 8 laterally mounted
auxiliary contacts (identical auxiliary switch blocks from S0 to
S12). Of these, no more than 4 are permitted to be NC contacts.

For accessories, see page 3/134, for spare parts, see page 3/144.
1) Built-in overvoltage damping: varistor circuit.
2) For more information on EMC, see LV 1 T .
3TF68/69 vacuum contactors are supplied with integrated overvoltage
damping for the main conducting paths (for description, see LV 1 T). The
overvoltage damping circuit is not required if 3TF68/69 contactors are
used in circuits with DC choppers, frequency converters or speedvariable drives, for example. It could be damaged by the voltage peaks
and harmonics and cause phase-to-phase short-circuits.
For this reason, the contactors can also be supplied without integrated
voltage damping. Without additional charge.
The order number must include "-Z" and the order code "A02".
* You can order this quantity or a multiple thereof.

3RA13, 3RA14 Contactor Assemblies
3RA13 Reversing Contactor Assemblies
3RA13 complete units, 3 ... 45 kW
■ Overview
The 3RA13 reversing contactor assemblies can be ordered as
follows:
Sizes S00 to S3
• Fully wired and tested, with mechanical and electrical
interlock (for voltages > 500 V, a dead interval of 50 ms on
reversing must be taken into account)
3
Sizes S00 to S12
• As components for customer assembly.
There is also a range of accessories (auxiliary switch blocks,
surge suppressors, etc.) that must be ordered separately.
Complete units
The fully wired reversing contactor assemblies are suitable for
use in any climate. They are finger-safe according to EN 50274.
The contactor assemblies consist of 2 contactors with the same
power, with one NC contact in the basic unit. The contactors are
mechanically and electrically interlocked (NC contact interlock).
For motor protection, either 3RU11 overload relays for direct
mounting or individual mounting or thermistor motor protection
tripping units must be ordered separately.
Components for customer assembly
For overload relays for motor protection, see "SIRIUS Overload
Relays".
Installation kits for all sizes are available for customer assembly
of reversing contactor assemblies.
The 3RA13 contactor assemblies have screw connections and
are suitable for screwing or snapping onto 35 mm standard
mounting rails.
Contactors, overload relays, the mechanical interlock (as of size
S0) and – for momentary-contact operation – auxiliary switch
blocks for latching must be ordered separately.

3RA13, 3RA14 Contactor Assemblies
3RA14 Contactor Assemblies for Wye-Delta Starting
3RA14 complete units, 3 ... 75 kW
Installation kits with wiring connectors and, if necessary,
mechanical connectors are available for contactor assemblies
for wye-delta starting. Contactors, overload relays, wye-delta
timing relays, auxiliary switches for electrical interlock – if
required also supply terminals, mechanical interlocks
(exception: in the case of the kit for size S00 contactor
assemblies the mechanical interlock between the delta
contactor and the wye contactor is included in the kit) and base
plates – must be ordered separately.
The wiring installation kits for sizes S00 and S0 contain the top
and bottom main conducting path connections between the line
and delta contactors (top) and between the delta and wye
contactors (bottom).

In the case of sizes S2 to S12 only the bottom main conducting
path connection between the delta and wye contactors is
included in the wiring connector, owing to the larger conductor
cross-section at the infeed.
Motor protection
Overload relays or thermistor motor protection trip units can be
used for overload protection.
The overload relay can be either mounted onto the line contactor
or separately fitted. It must be set to 0.58 times the rated motor
current.

12.5 ... 50 kvar
■ Overview
AC operation
IEC 60947, EN 60947 (VDE 0660)
The contactors are suitable for use in any climate. They are
finger-safe according to EN 50274.
3
The 3RT16 capacitor switching contactors are special variants
of the size S00 to S3 SIRIUS contactors. The capacitors are
precharged by means of the mounted leading NO contacts and
resistors; only then do the main contacts close.
This prevents disturbances in the power system and welding of
the contactors.
Only discharged capacitors are permitted to be switched on
with capacitor contactors.
The auxiliary switch block which is snapped onto the capacitor
contactor contains the three leading NO contacts and in the
case of S00 one standard NC contact (in addition to one
NO contact in the basic unit) and in the case of S0 and S3 one
standard NO contact, which is unassigned. Size S00 also
contains another unassigned NO contact in the basic unit.
In addition, a 2-pole auxiliary contact block can be mounted
laterally on the 3RT16 47 capacitor contactors (2 NO, 2 NC or
1 NO + 1 NC versions); type 3RH19 21-1EA.. . The fitting of
auxiliary switches for 3RT16 17 and 3RT16 27 is not
expandable.
For the capacitor making and switching capacity of the basic
3RT10 contactor variant, see Technical Specifications.

3RH11 contactor relays
■ Overview
3RH11..-0LA0
The DC solenoid systems of the contactor relays are modified
(to hold-in coil) by means of a series resistor.
DC operation
IEC 60947-4-1, EN 60947-4-1 (VDE 0660, Part 102), for
requirements according to IEC 60077-1 and IEC 60077-2.
The size S00 contactor relays are supplied prewired with a plugon module containing the series resistor. The varistor is
integrated. A 4-pole auxiliary switch block (according to
EN 50005) can be fitted additionally.
The contactor relays are finger-safe according to EN 50274. The
size S00 contactor relays have Cage Clamp connections for all
terminals.
Mounting
Ambient temperature
The permissible ambient temperature for operation of the
contactor relays (across the full coil operating range) is
-40 °C to +70 °C.
3
At ambient temperatures up to 70 °C, the size S00 contactor
relays are allowed to be mounted side by side.
3RH1122-2K.40
These contactor relays have an extended tolerance from 0.7 to
1.25 x Us; the coils are fitted with varistors as standard.
An additional series resistor is not required. Please note:
• Size S00: It is not possible to mount an auxiliary switch block.
Uninterrupted duty at temperatures > +55 °C reduces the
mechanical endurance, the current-carrying capacity of the
conducting paths and the operating frequency.
■ Application
At ambient temperatures > 60 °C ˆ 70 °C, a clearance of 10 mm
is required when they are mounted side by side.
For operation in installations which are subject both to
considerable variations in the control voltage and to high
ambient temperatures, e.g. railway applications under extreme
climatic conditions, rolling mills, etc.
Control and auxiliary circuits
The coils of the contactor relays have an extended tolerance
from 0.7 to 1.25 x Us and are fitted as standard with varistors to
provide protection against voltage surges. The opening delay is
consequently 2 to 5 ms longer than for standard contactors.

3RT, 3RH, 3TB, 3TC, 3TH, 3TK Contactors for Special Applications
Contactors with Extended Tolerance 0.7 ... 1.25 x Us , for Railway Applications
3RT10 motor contactors, 5.5 ... 45 kW
DC operation
IEC 60947-4-1, EN 60947-4-1 (VDE 0660, Part 102), for
requirements according to IEC 60077-1 and IEC 60077-2.
The contactors are finger-safe according to EN 50274 (exception: series resistors S0 to S3). The contactors are available with
both Cage Clamp and screw terminals. The size S00 contactors
have Cage Clamp terminals for all connections. The auxiliary
conductor and coil terminals of sizes S0 to S3 are all Cage
Clamp terminals.
These contactors have an extended tolerance from 0.7 to
1.25 x Us; the coils are fitted with varistors as standard.
An additional series resistor is not required.
Please note:
• Size S00: it is not possible to mount an auxiliary switch block.
• Size S0: up to two single-pole auxiliary switch blocks can be
mounted.
At ambient temperatures > 60 °C ˆ 70 °C, a clearance of 10 mm
is required when they are mounted side by side.
3RT10 contactors with contactor control unit, extended
tolerance
Ambient temperature
Control and auxiliary circuits
The permissible ambient temperature for operation of the
contactors (across the full coil operating range) is -40 °C to
+70 °C.
The coils of the contactors have an extended tolerance from
0.7 to 1.25 x Us and are fitted as standard with varistors to
provide protection against voltage surges. The opening delay is
consequently 2 ms to 5 ms longer than for standard contactors.
Uninterrupted duty at temperatures > +55 °C reduces the
mechanical endurance, the current-carrying capacity of the
conducting paths and the operating frequency.
Dimensions
Attaching resistors increases the width of contactor sizes S0 to
S3 (see Dimensional Drawings).
■ Application
For operation in installations which are subject both to considerable variations in the control voltage and to high ambient temperatures, e.g. railway applications under extreme climatic conditions, rolling mills, etc.
Control and auxiliary circuits
The coils of the contactors have an extended tolerance from 0.7
to 1.25 x Us and are fitted as standard with varistors to provide
protection against voltage surges. The opening delay is
consequently 2 to 5 ms longer than for standard contactors.
3RT10 ..-0LA0
The DC solenoid systems of the contactors are modified (to
hold-in coil) by means of a series resistor.
The size S00 contactors are supplied prewired with a plug-on
module containing the series resistor. The varistor is integrated.
A 4-pole auxiliary switch block (according to EN 50005) can be
fitted additionally.
3RT10 ..-.X.40-0LA2
The contactors are energized using series-connected control
electronics, ensuring the coil operating range of 0.7 to 1.25 x Us
at an ambient temperature of 70 °C. They are supplied as
complete self-contained units with a built-on contactor control
unit. A varistor is integrated for damping opening surges in the
coil.
The possibility of mounting auxiliary switches is the same as that
for equivalent standard contactors.
Mounting
At ambient temperatures up to 70 °C, sizes S0 to S3 of these
contactor versions are allowed to be mounted side by side.
Ambient temperature
The permissible ambient temperature for operation of the
contactors (across the full operating range of the coils)
is -40 °C to +70 °C.
Uninterrupted duty at temperatures > +55 °C reduces the
mechanical endurance, the current-carrying capacity of the
conducting paths and the operating frequency.
Dimensions
Because of the built-on contactor control unit, the height of the
size S0 to S3 contactors increases by up to 34 mm (see
Dimensional Drawings).
The size S0 to S3 contactors are equipped on the front with an
auxiliary switch block with 2 NO + 2 NC contacts. The separate
series resistor, which is attached laterally next to the contactor
on the 35 mm standard mounting rail, is fitted with connecting
leads for mounting the contactors. A circuit diagram showing the
terminals is stuck onto each contactor. One NC of the auxiliary
contacts is required for the series resistor function. The selection
and ordering data shows the number of additional, unassigned
auxiliary contacts. It is only possible to extend the number of
auxiliary contacts with size S00.
Mounting
At ambient temperatures up to 70 °C, the size S00 contactors
and contactor relays are allowed to be mounted side by side.
The resistor module of the size S0 to S3 contactors must be
mounted to the left of the contactor owing to the prefabricated
connecting leads.
