Inspecting and testing

before use

Initial tests

_Procedure

A general check of the circuit breaker takes only a few minutes and avoids any risk of mistakes due to errors or negligence.

A general check must be carried out:

bprior to initial use

bfollowing an extended period during which the circuit breaker is not used.

A check must be carried out with the entire switchboard de-energised.

In switchboards with compartments, only those compartments that may be accessed by the operators must be de-energised.

Electrical tests

Insulation and dielectric-withstand tests must be carried out immediately after delivery of the switchboard. These tests are precisely defined by international standards and must be directed and carried out by a qualified expert. Prior to running the tests, it is absolutely necessary to:

bdisconnect all the electrical auxiliaries of the circuit breaker (MCH, MX, XF, MN)

bremove the long-time rating plug on the 2.0, 6G control units. Removal of the

rating plug disconnects the voltage measurement input.

Switchboard inspection

Check that the circuit breakers are installed in a clean environment, free of any installation scrap or items (tools, electrical wires, broken parts or shreds, metal objects, etc.).

Conformity with the installation diagram

Check that the devices conform with the installation diagram:

bbreaking capacities indicated on the rating plates

bidentification of the control unit (type, rating)

bpresence of any optional functions (remote ON/OFF with motor mechanism,

auxiliaries, measurement and indication modules, etc.)

bprotection settings (long time, short time, instantaneous, earth fault)

bidentification of the protected circuit marked on the front of each circuit breaker.

Condition of connections and auxiliaries

Check device mounting in the switchboard and the tightness of power connections. Check that all auxiliaries and accessories are correctly installed:

belectrical auxiliaries

bterminal blocks

bconnections of auxiliary circuits.

Operation

Check the mechanical operation of the circuit breakers:

bopening of contacts

bclosing of contacts.

Check on the control unit

Check the control unit of each circuit breaker using the respective user manuals.

These operations must be carried out in particular before using a Easypact device for the first time.

Note the fault

Faults are signalled locally and remotely by the indicators and auxiliary contacts installed on circuit breakers (depending on each configuration). See page 12 in this manual and the user manual of the control unit for information on the fault indications available with your circuit breaker.

Identify the cause of tripping

A circuit must never be reclosed (locally or remotely) before the cause of the fault has been identified and cleared.

A fault may have a number of causes:

bdepending on the type of control unit, fault diagnostics are available. See the user

manual for the control unit.

bdepending on the type of fault and the criticality of the loads, a number of

precautionary measures must be taken, in particular the insulation and dielectric tests on a part of or the entire installation. These checks and test must be directed and carried out by qualified personnel.

Inspect the circuit breaker following a short-circuit

bCheck the arc chutes (see page 40)

bCheck the contacts (see page 40)

bCheck the tightness of connections (see the device installation manual)

bCheck the disconnecting-contact clusters (see page 40).

Reset the circuit breaker

The circuit breaker can be reset locally or remotely. See page 12 in this manual for information on how the circuit breaker can be reset.
