A 630 A circuit breaker, to reinforce the
power supply safety of your lines
One of the means by which a power distributor can improve service quality in the
network and lower installation costs, is to set up a two-level structure with a main ring
distributing power to secondary rings connected to MV/LV transformers.
The RM6 range 630A circuit breaker has been designed to provide the protection for
this intermediate level.
With its independent protection sequence, it detects a cable fault (either phase to
phase or zero sequence) and instantly isolates it.
The VIP 300 protection relay, which is in complete conformity with IEC 60255
recommendations, offers a complete range of protection curves in order to adapt to
different discrimination needs with the main protection upstream.
With this ring protection circuit breaker
b You benefit from our experience in independent protection systems and low
pressure breaking technologies.
b You are provided with switchgear which, motorized either as a factory-built feature
or as an on-site upgrade option without interrupting service, is designed to integrate
perfectly into the telecontrol of up-to-date distribution networks.
A new range that is extensible on site
When harsh climatic conditions or environmental restrictions make it necessary to
use compact switchgear, but the foreseeable evolution of the power distribution
network makes it necessary to provide for future changes, RM6 offers a range of
extensible switchgear.
The addition of one or more functional units can be carried out by simply adding
stand-alone modules that are connected to each other at busbar level by directed
field bushings.
This very simple operation can be carried out on-site:
b without handling any gas,
b without any special tooling,
b without any particular preparation of the floor.
The only technical limitation to the evolution of an extensible RM6 switchboard
is therefore that of keeping to the rated current of the busbar.

Main characteristics
Description of RM6 switchgear
RM6 switchgear comprises 1 to 4 integrated, low dimension functional units.
This self-contained, totally insulated unit comprises:
b a stainless steel, gas-tight metal enclosure, sealed for life, which groups together
the live parts, switch-disconnector, earthing switch, fuse switch or the circuit breaker,
b one to four cable compartments with interfaces for connection to the network or to
the transformer,
b a low voltage compartment,
b an electrical operating mechanism compartment,
b a fuse chamber compartment for fused switch-disconnectors or fuse switches.
The performance characteristics obtained by the RM6 meet the definition of a
"sealed pressure system" laid down in the IEC recommendations.
The switch-disconnector and the earthing switch offer the operator all necessary
usage guarantees:
Tightness
The enclosure is filled with SF6 at a 0.2 bar gauge pressure. It is sealed for life after
filling. Its tightness, which is systematically checked at the factory, gives the
switchgear an expected lifetime of 30 years. No maintenance of live parts is
necessary with the RM6 breaking.
Switch disconnector
Electrical arc extinction is obtained using the SF6 puffer technique.
Circuit breaker
Electrical arc extinction is obtained using the rotating arc technique plus SF6
auto-expansion, allowing breaking of all currents up to the short-circuit current.

Description of the

Safety of people
Switchgear
Switch-disconnectors and circuit breakers have similar architecture:
b a moving contact assembly with 3 stable positions (closed, open and earthed)
moves vertically (see sketch). Its design makes simultaneous closing of the switch
or circuit breaker and the earthing switch impossible,
b the earthing switch has a short-circuit making capacity, as required by the
standards,
b the RM6 combines both the isolating and interrupting functions,
b the earth collector has the correct dimensions for the network,
b access to the cable compartment can be interlocked with the earthing switch and/
or the switch or circuit breaker.
3 stable position switch
Reliable operating mechanisms
The electrical and mechanical operating mechanisms are located behind a front plate
displaying the mimic diagram of the switchgear status (closed, open, earthed):
b closing: the moving contact assembly is manipulated by means of a fast-acting
operating mechanism . Outside these manipulations, no energy is stored.
For the circuit breaker and the fuse-switch combination, the opening mechanism is
charged in the same movement as the closing of the contacts.
b opening: opening of the switch is carried out using the same fast-acting
mechanism, manipulated in the opposite direction.
For the circuit breaker and fuse-switch combination, opening is actuated by:
v a pushbutton,
v a fault.
b earthing: a specific operating shaft closes and opens the earthing contacts. The
hole providing access to the shaft is blocked by a cover which can be opened if the
switch or circuit breaker is open, and remains locked when it is closed.
b switchgear status indicators: are placed directly on the moving contact
assembly operating shafts. They give a definite indication of the position of the
switchgear (attachment A of IEC standard 60129).
b operating lever: this is designed with an anti-reflex device which prevents any
attempt to immediately reopen the switch-disconnector or the earthing switch after
closing.
b padlocking facilities: 1 to 3 padlocks can be used to prevent:
v access to the switch or circuit breaker operating shaft,
v access to the earthing switch operating shaft,
v operation of the opening pushbutton.
Earthing display
b earthing switch closed position indicators: these are located on the upper part
of the RM6. They can be seen through the transparent earthing covers, when the
earthing switch is closed.
Internal arc withstand
The robust, reliable and environmentally insensitive design of the RM6 makes it
highly improbable that a fault will appear inside the switchgear.
Nevertheless, in order to ensure maximum personal safety, the RM6 is designed to
withstand an internal arc supplied by a rated short-circuit current for 1 second,
without any danger to the operator.
Accidental overpressure due to an internal arc is limited by the opening of the safety
valve, at the bottom of the metal enclosure.
The gas is released to the rear of the RM6 without affecting conditions in the front.
After standard testing carried out for 20 kA, 1s, the device meets the six criteria
defined by appendix AA of IEC 60298.

RM6 range
Schneider Electric
Description of the
switchgear
Insensitivity to the environment
Complete insulation
b A metal enclosure made of stainless steel, which is unpainted and gas-tight
(IP67), contains the live parts of the switchgear and the busbars;
b Three sealed fuse chambers, which are disconnectable and metallized on the
outside, insulate the fuses from dust, humidity...
b Metallization of the fuse chambers and directed field terminal connectors
confines the electrical field in the solid insulation.
Taken together, the above elements provide the RM6 with genuine total insulation
which makes the switchgear completely insensitive to environmental conditions,
dust, extreme humidity, temporary soaking.
(IP67: immersion for 30 mn, as laid down in IEC standard 60529, § 14.2.7).
Operating safety
Cable insulation test
In order to test cable insulation or look for faults, it is possible to inject a direct
current of up to 42 kVdc for 15 minutes through the cables via the RM6, without
disconnecting the connecting devices.
The earthing switch is closed and the moving earthing connection is opened in order
to inject the voltage via the "earthing covers". This system, a built-in feature of the
RM6, requires the use of injection fingers (supplied as an option).
Voltage indicator lamps
A device (supplied as an option) on all functional units makes it possible to check the
presence (or absence) of voltage in the cables.
Tow types of indicator can be proposed according to network operating habits:
b A device with built-lamps, of the VPIS type (Voltage Presence Indicating System)
complying with standard IEC 61958,
b or a system with separate luminous modules, of the VDS type (Voltage Detection
System) complying with sandard IEC 61243-5.

Transformer protection
Using fuse switches
Fuse dimensions
Ratings for fuses for transformer protection depend, among other points, on the
following criteria:
b service voltage,
b transformer rating,
b thermal dissipation of the fuses,
b fuse technology,
Two types of fuse may be installed:
b Solefuse type: according to UTE NFC 64.210 standard, with or without strikereur,
b Fusarc CF type: according to DIN 43.625 dimensional standard, with or without
striker.
Example (using the selection table below) general case, for protection of a 400 kVA
transformer at 10 kV, either Soléfuse fuses with a rating of 63 A or Fusarc CF fuses
with a rating of 50 A are chosen.

VIP 30 and VIP 35 are self-powered relays, requiring no auxiliary power supply,
which are fed by current sensors, activating a MITOP release.
VIP30 protects against phase to phase faults.
VIP35 protects against phase to phase faults and earth faults.
s
Description
b the relays are assembled in a housing, and the front faces are protected a
transparent cover. The whole assembly has a degree of protection of IP54,
b settings are made on the front, using rotary switches,
b the phase operating current is adjusted directly according to the transformer rating
and the operating voltage,
b the earth current set point is adjusted according to the network characteristics.
Phase protection
b phase protection is provided by an IDMT set point which operates as of 1.2 times
the operating current (Is). VIP 30 and VIP 35 phase protections are identical.
Earth protection
b earth fault protection operates with measurement of the residual current carried
out using the sum of the secondary currents of the sensors,
b earth protection operates in definite time: both its set point and time delay are
adjustable.

Line protection
Using a 630 A circuit breaker
The 630 A circuit breaker has been designed to protect medium voltage feeders as
near to the fault as possible. The protection unit is identical to that of the 200 A circuit
breaker, with a VIP 300 relay adapted to network protection.
VIP 300 self-powered protection relay
b VIP 300 protects against phase to phase faults and earth faults. The choice of
tripping curves, and the multiplicity of settings enable it to be used with a wide variety
of discrimination plans.
b VIP 300 is a self-powered relay which obtains its power supply from current
sensors. It does not need an auxiliary power supply. It actuates a release.
VIP 300
Description
The operating principle of the protection unit is the same as for the VIP 300 and
VIP 35 relays.
Phase protection
b Phase protection has two independently adjustable set points:
v either an IDMT or definite low set point can be selected. The IDMT curves are in
conformity with the IEC 60255-3 standard. They are of the inverse, very inverse and
extremely inverse type,
v the high set point is a definite time one.
Earth protection
b Earth fault protection operates with measurement of the residual current carried
out using the sum of the secondary currents of the sensors.
b As with phase protection, earth protection has two independently adjustable set
points.
Indication
b Two indicators show the origin of tripping (phase or earth). They remain in position
after the relay power supply is cut off.
b Two LED indicators (phase and earth) indicate that the low set point has been
exceeded and its time delay is in progress.

Selection of connections
General
b The profiles, contacts and dimensions of the RM6 connection interfaces are
defined by the EN50181 standard.
b 100% of the epoxy resin interfaces undergo dielectric testing at power frequency
and partial discharge tests.
Appropriateness for use
Types of connection interface
The bushings carry the electrical current from the outside to the inside of the
enclosure, which is filled with SF6 gas, ensuring insulation between the live
conductors and the frame.
There are 3 types of bushing, which are defined by their short-time withstand
current:
type A: 200 A: 12,5 kA 1 s and 31,5 kA peak (plug-in)
type B: 400 A: 16 kA 1 s and 40 kA peak (plug-in)
type C: 630 A: 25 kA 1 s and 62,5 kA peak (disconnectable M16)
How to define the connection interface
The connection interfaces depend on specific criteria, such as:
Installation
b current rating of the connected equipment: 200, 400, 630 A
b short-time withstand current for 12.5 kA, 16 kA, 25 kA switch and circuit breaker
functions
b for the fuse-switch combination function, as the short-circuit current is limited by
the fuse, the connection interface will be of type A (200 A)
b minimum phase expansion length
b connection type:
v plug in: multicontact ring
v disconnectable: bolted
b output position: straight, elbow
This informations must be specified for
better definition of the connection
interfaces.

Installation, maintenance
Phase concordance unit
This unit is used to check phase concordance.
It can be connected to any voltage indicator lamp device.
Protection relay test
b the portable VAP6 unit is connected to the circuit breaker protection relay:
v injecting an electrical stimulus, two pushbuttons are used to check that the
short-circuit and zero sequence fault current protection devices are operating
v an extra pushbutton may be provided to inhibit tripping of the circuit breaker.
Local operation
Voltage indicator lamp
There is a voltage indicator device on network switches, circuit breakers and
fuse-switch combinations, which makes it possible to check whether or not there is
a voltage across the cables.
Two devices are offered:
b VDS: Voltage Detecting System
b VPIS: Voltage Presence Indication System
Short-circuit indicator
b Built into the switchgear:
Each switch can be fitted with an Alpha type short-circuit indicator (Hortsmann).
If an RM6 is operated remotely, this function is integrated into the Talus 200
telecontrol interface.
b To be installed in the kiosk:
The FLAIR range is designed for the tracking of permanent faults on MV cable
networks. Thanks to an ammeter or directional fault detection scheme it covers the
needs of all types of MV networks. Available in weatherproof or non-weatherproof
enclosures, LV battery back, DC, or battery-only power supplies, the FLAIR range is
very versatile and offers more than 15 versions.

Switch operating mechanism
b the switch operating mechanism includes a space that is reserved for the
installation of a geared motor. This can be installed at the factory, but it can also the

dismantling the operating mechanism.
b an electrical interlocking assembly prohibits any false operations.
Once motorized, the RM6 integrates perfectly into a telecontrol system.
Circuit breaker operating mechanism
b circuit breaker protection functional units can be equipped with a geared motor.
This can be installed at the factory, but it can also be installed on-site, by the
customer, without de-energizing the unit, and without dismantling the operating
mechanism.
b electrical locking prohibits any false operations, with, as an option, closing after
an unacknowledged fault. Once motorized, the RM6 integrates perfectly into a
telecontrol system.
This option becomes particularly useful in the context of the protection of a
secondary ring, with supervision by a telecontrol system.
Auxiliary contacts
Each switch or circuit breaker can be fitted with 4 auxiliary contacts with the
following positions: 2 N/O and 2 N/F.
Each earthing switch can be fitted with 1 auxiliary contact with the following position:
(opening/closing).
Each circuit breaker can be fitted with 1 fault indication auxiliary contact.
Each fuse-switch combination can be fitted with 1 blown fuse indication auxiliary

Additional raising plinth
As an option, the RM6 can be fitted with a 260 or 520 mm raising plinth.
This addition, which simplifies civil engineering works, results in trenches of a
smaller depth, or even in their complete elimination when the bending radius of the
cables allows it.
The plinth is mounted directly on the floor.

For "transformer"
connection via fuse-switch
The cross-sections of "transformer" cables are
generally smaller than those of the "network" cables.
All the cables are then run through the same space.
When straight MV connectors are used, the depth P
indicated below can be greater than that of the
"network" cables.

Quality Assurance
Certified quality: ISO 9001
A major plus point
Merlin Gerin has integrated a functional organization into each of its units, the main
purpose of which is to check quality and ensure the adherence to standards.
This procedure is:
b the same throughout the different departments,
b recognized by numerous approved customers and organizations.
Above all, it is our strict application of this functional organization that has enabled
us to obtain the recognition of an independent organization, the French Association
for Quality Assurance (Association Française pour l'Assurance Qualité, or (AFAQ).
The RM6 design and production quality system has been certified as being in
conformity with the requirements of the ISO 9001 and ISO 9002 quality
assurance model.

Rigorous, systematic checks
During the manufacture of each RM6, it undergoes systematic routine tests, the aim
of which is to check quality and conformity:
b tightness check
b filling pressure check
b opening and closing speed measurement
b operating torque measurement
b partial discharge check
b dielectric check
b conformity with drawings and diagrams.
The quality control department records and signs the results obtained on the test
certificate for each device.

Preserving the
environment
The Schneider recycling
procedure
The Schneider recycling procedure for
SF6 based products is subject to
rigorous management, and allows each
device to be traced through to its final
destruction documentation.
Schneider Electric is committed to a long term environmental approach.
As part of this, the SM6 range has been designed to be environmentally friendly,
notably in terms of the product's recycleability.
The materials used, both conductors and insulators, are identified and easily
separable.
At the end of its life, SM6 can be processed, recycled and its materials recovered in
conformity with the draft European regulations on the end-of-life of electronic and
electrical products, and in particular without any gas being released to the
atmosphere nor any polluting fluids being discharged.
