The experience of a world leader
MT20140
The Schneider Electric group’s experience extends over forty years
in factory-built cubicles and over twenty five years in SF6 technology
for Medium Voltage switchgear.
This experience means that today Schneider Electric can propose
a complementary range: DMV-A, DMV-D, DMV-S vacuum type circuit breaker
cubicles and internal arc cubicles 16 kA.1 s to reinforced the safety of people.
This gives you the advantage of unique experience, that of a world leader, with over
half a million SF6 Medium Voltage units installed throughout
the world.
Putting this experience at your service and remaining attentive to your
requirements is the spirit of active partnership that we want to develop
in offering you the SM6 range.
MT20141
The modular SM6 range is a range of harmonised cubicles equipped
with SF6 or vacuum air breaking technology switchgear.
These cubicles allow you to produce all your Medium Voltage substation
requirements up to 24 kV by superposing their various functions.
The result of in-depth analysis of your requirements, both now and in the future,
SM6 cubicles mean that you can take advantage of all the features of both a modern

A major advantage
MT55055
MT55054
Schneider Electric has integrated a functional organisation into each
of its units. The main mission of this organisation is to check the quality
and the compliance with standards.
This procedure is:
b uniform throughout all departments;
b recognised by many customers and approved organisations.
But it is above all its strict application that has enabled recognition
to be obtained by an independent organisation:
The French Quality Assurance Association (FQAA).
The quality system for the design and manufacture of SM6 units
has been certified in conformity with the requirements of the ISO 9001 quality
and ISO 9002 quality assurance model.
61002N
Meticulous and systematic controls
During manufacture, each SM6 is subject to systematic routine testing which aims
to check the quality and conformity:
b sealing testing;
b filling pressure testing;
b opening and closing rate testing;
b switching torque measurement;
b dielectric testing;
b conformity with drawings and plans.
The results obtained are written and reported on the test certificate for each device
by the quality control department.
61003N
The environmental management system adopted by Schneider Electric production
sites that produce the SM6 have been assessed and judged
to be in conformity with requirements in the ISO 14001 standard.

Operating conditions
In addition to its technical characteristics, SM6
meets requirements concerning protection of life
and property as well as ease of installation,
operation and protecting the environment.
SM6 units are designed for indoor installations (IP2XC).
Their compact dimensions are:
b 375 mm to 750 mm wide;
b 1600 mm high;
b 840 mm deep…
… this makes for easy installation in small rooms or prefabricated substations.
Cables are connected via the front.
All control functions are centralised on a front plate, thus simplifying operation.
The units may be equipped with a number of accessories (relays, toroids,
instrument transformers, surge arrestor, telecontrol, etc.).

natural interlocking system that prevents incorrect operation.
Moving-contact rotation is driven by a fast-acting mechanism that is independent
of the action of the operator.
v the device combines the breaking and disconnection functions.
v the earthing switch placed in the SF6 has a short-circuit making capacity,
in compliance with standards.
v any accidental over-pressures are eliminated by the opening of the safety membrane, in which
case the gas is directed toward the back of the unit, thus avoiding projection or other related

circuit breaker.
This process diffuses the arc in a regular manner with high currents.
It ensures optimum distribution of the energy along the compact surface
so as to avoid local hot spots.
The advantages of this technique:
v a simplified vacuum type circuit breaker which is consequently very reliable,
v low dissipation of arcing energy in the circuit breaker,
v highly efficient contacts which do not distort during repeated breaking,
v significant reduction in control energy.

b Switchgear status indicator:
Fitted directly to the mobile equipment’s shaft, these give a definite indication
of the switchgear’s position. (appendix A of standard IEC 62271-102.).
b Operating lever:
This is designed with an anti-reflex device that stops any attempt to re-open
the device immediately after closing the switch or the earthing disconnector.
b Locking device:
Between one and three padlocks enable the following to be locked:
v access to the switching shaft of the switch or the circuit breaker,
v access to the switching shaft of the earthing disconnector,
v operating of the opening release push-button.
Simple and effortless switching
Mechanical and electrical controls are side by side on the front fascia, on a panel including
the schematic diagram indicating the device’s status (closed, open, earthed):
b Closed: the mobile equipment is operated via a quick acting mechanism, independent of
the operator. No energy is stored in the switch, apart from
when switching operations are taking place.
For combined switch fuses, the opening mechanism is armed at the same time
as the contacts are closed.
b Opening: the switch is opened using the same quick acting mechanism,
operated in the opposite direction.
For circuit breakers and the combined switch fuses, opening is controlled by:
v a push-button,
v a fault.
b Earthing: a specific control shaft enables the opening or closing of the earthing contacts.
Access to this shaft is blocked by a cover that can be slid back if the switch is open but which
remains locked in place if it is closed.
Voltage presence indicator
This device has integrated VPIS (Voltage Presence Indicating System) type lights,
in conformity with IEC standard 61958, enabling the presence (or absence) of voltage to be

By internal arc protection
Standard IEC 60298 appendix AA indicates a
method for testing switchgear in metal
enclosures under internal arcing conditions. The
aim of this test is to show that an operator
present in front of a switchboard would be
protected against the effects
of an internal fault.
To enhance the safety of people, it is desirable to provide as high a degree
of protection as possible by evacuating the effects of internal arcing using:
b evacuation systems which direct gases towards the top or the bottom
of the switchboard enabling over pressure to be limited in the case
of an internal fault in the compartments;
b channelling and evacuating hot gases towards an external area, which is not hazardous for
the operator;
b materials which are non-inflammable for the cubicle;
b reinforced panels.
Consequently:
The SM6 is designed to offer a good level of safety

b Control of the architecture:
v compartment type enclosure.
b Technological control:
v electrotechnical: modelling of electrical fields,
v mechanical: parts produced using CAD systems.
b Use of reliable components:
v choice of materials,
v earthing switch with closing capacity.
b Devices for total operating safety:
v voltage presence indicator on the front face,
v natural reliable interlocking,
v locking using keys or padlocks.

v enhanced internal arcing withstand: 16 kA. 1 s.
SM6 internal arc (in conformity with IEC 60298 appendix
AA)
In its internal arc version, the SM6 range has successfully passed all of the type testing
relative to standard IEC 60298 (6 acceptance criteria).
The materials used meet the constraints for which the SM6 is designed.
The thermal and mechanical forces that an internal arc can produce are perfectly absorbed by
the enclosure.
An operator present in the front of the SM6 switchboard during an internal fault
will not be exposed to the effects of arcing.
Case of an SM6 switchboard installed in the middle of a room
downwards exhaust: 4-sides internal arc protection
SM6 proposes several options to install an internal arc
enhanced switchboard
b 3-sides internal arc protection:
Case of an SM6 switchboard positioned against the wall, access to the rear
of the cubicles is impossible, internal arc protection on three sides is sufficient.
b 4-sides internal arc protection:
For SM6 switchboards installed in the middle of a room, 4-sides internal arc protection is
necessary in order to protect an operator moving around the switchboard.
Choice of exhaust
The choice depends on the civil engineering:
b Upwards exhaust:
A ceiling height greater than 2200 mm is necessary.
b Downwards exhaust:
Civil engineering with an adequate volume is necessary.

Phase protection
b phase protection is via two independently adjustable thresholds:
v the lower threshold can be chosen to be inverse definite time or definite time.
The definite time curves are in conformity with IEC standard 60255-3.
They are either of inverse, very inverse or extremely inverse type.
v the upper threshold is inverse definite time.
Earthing protection
b protection against phase-to-earth faults uses the residual current measurement,
taken from the sum of the secondary currents in the sensors. This is taken via a CRa X1 gauge:
10 to 50 A and X4: 40 to 200 A
or via a CRb X1 gauge: 63 to 312 A and X4: 250 A to 1250 A.
b as for phase protection, phase-to-earth protection had two thresholds
that can be independently set.
Signalling
b two indicators show the origin of the trip operation (phase or earth).

Charging motor and associated mechanism (MCH)
MT55165
The MCH unit arms and rearms the energy storage springs as soon as
the circuit breaker is closed. This enables instant reclosing of the device
after opening. The arming lever is only used as back up control in the absence
of an auxiliary voltage.
The MCH is equipped as standard with a CH limit switch.
This contact indicates the “armed” position of the mechanism (spring armed).

Any tripping caused by the Mitop release is indicated momentarily by an SDE type
changeover contact. This release unit also includes a coil enabling the remote rearming of the
SDE contact.
Comment: to use the MITOP release requires the adjustment of a time delay to be set
by the protection relay in order to ensure a circuit breaker operating time of 45-50 ms.

Motors protection with CRM units
The current rating of fuses installed in CRM units depends
on:
b motor current rating In;
b starting current Id;
b frequency of starts.
The fuses rating is calculated such that a current equal to
twice the starting current does not blow the fuse within
period equal to the starting time.
The adjacent table indicated the ratings which should be
used, based on the following assumptions:
b direct on-line startup;
b Id/In ð 6;
b pf = 0.8 (P ð 500 kW) or 0.9 (P > 500 kW);
b h = 0.9 (P ð 500 kW) or 0.94 (P > 500 kW).
The indicated values are for Fusarc fuses
(to DIN standard 43-625).
Selection of fuses
Id = 6 x In = 780 A
Then select the next higher value, i.e. 790 A.
For six 5-second starts per hour, select fuses
rated 200 A.
Note: the same motor could not be protected for 12 starts
per hour since the maximum service voltage for the required 250 A
rated fuses is 3.3 kV.
The color code is linked to the rated voltage of the fuse.

Access to fuses
Access is via the front with the front panel removed.
Fuses may be removed without tools by simply pulling them forward.
The field deflector pivots and automatically returns to its position.
Replacement of fuses
When fault clearance results in one or two blown fuses, it is still common practice
to replace only the blown fuses.
However, though the remaining fuse(s) may apparently be in good condition,
their operating characteristics are generally reduced due to the short-circuit.
If non-blown fuses remain in service, they may blow even at very low
over-current values.
In systems where continuity of service is of importance, it is recommended
to replace all three fuses, in compliance with IEC recommendation 60282.1.
Please note: all three fuses must come from the same range:
Fusarc or Fusarc CF (they have different fusion curves).

The ageing resistance of the equipment in an MV/LV substation
depends on three key factors:
b the need to make connections correctly
New cold fitted connection technologies offer ease of installation that favours resistance over
time. Their design enables operation in polluted environments
under severe conditions.
b the impact of the relative humidity factor
The inclusion of a heating element is essential in climates with high humidity levels
and with high temperature differentials.
b ventilation control
The dimension of the grills must be appropriate for the power dissipated
in the substation. They must only traverse the transformer area.
Network cables are connected:
b on the switch terminals;
b on the lower fuse holders;
b on the circuit breaker’s connectors.
The bimetallic lugs are:
b round connection and shank for cables ð 300 mm2;
b square connection round shank for cables > 300 mm2 only.
Crimping of lugs to cables must be carried out by stamping.
The end connectors are of cold fitted type
Schneider Electric’s experience has led it to favour this technology wherever possible for
better resistance over time.
The maximum admissible cable cross section:
b 630 mm2 for 1250 A incomer and feeder cables;
b 300 mm2 for 400 - 630 A incomer and feeder cables ;
b 95 mm2 for transformer protection cubicles with fuses.
Access to the compartment is interlocked with the closing of the earthing disconnector.
The reduced cubicle depth makes it easier to connect all phases.
A 12 mm Ø pin integrated with the field distributor enables the cable end lug
to be positioned and attached with one hand. Use a torque wrench set to 50 mN.

Floor preparation
Units may be installed on ordinary concrete floors, with or without trenches depending on the
type and cross-section of cables.
Required civil works are identical for all 400 - 630 A units.
To reduce the depth of trenches by 400 mm (for the 400 - 630 A units),
which in many cases is sufficient to eliminate trenches altogether,
units may be installed on a concrete footing prepared when pouring the floor.
Installation of 400 - 630 A units on a footing:
b enables installation in rooms where trenches are not possible;
b in no way affects substation switching operation;
b for the 1250 A units DM1-A and DM1-W, a floor void must be foreseen.

With each other
The units are simply bolted together to form the MV switchboard (bolts supplied). Busbar
connections are made using a torque wrench set to 28 mN.
On the floor
b for switchboards comprising up to three units, the four corners of the switchboard must be
secured to the floor using:
v M8 bolts (not supplied) screwed into nuts set into the floor using a sealing pistol,
v screw rods grouted into the floor.
b for switchboards comprising more than three units, the number and position
of fixing points depends on local criteria (earthquake withstand capacities, etc.),
each unit may be fixed as necessary.
b position of fixing holes b depends on the width a of units:
12.3 x 12.3
Note: in circuit-breaker or contactor units, fixing devices
are installed on the side opposite the switchgear.
