Closing the circuit breaker

Device "ready to close"

Closing conditions

E51291A

Closing (i.e. turning the circuit ON) is possible only if the circuit breaker is "ready to close". The prerequisites are the following: bb device open (OFF) bb springs charged bb no opening order present.

E51292A

Device not "ready to close"

The circuit breaker will not close unless it is "ready to close" when the order is given.

Closing the circuit breaker E51493A

Remotely When connected to a remote control panel, the XF closing release can be used to close the circuit breaker remotely.

Anti-pumping function

The purpose of the mechanical anti-pumping function is to ensure that a circuit breaker receiving simultaneous opening and closing orders does not open and close indefinitely. If there is a continuous closing order, after opening the circuit breaker remains open until the closing order is discontinued. A new closing order is required to close the circuit breaker. A new order is not required if the closing release is wired in series with the PF "ready to close" contact.

These operations require that all chassis-locking functions be disabled (see page 19).

Prerequisites

To connect and disconnect Easypact, the crank must be used. The locking systems, padlocks and the racking interlock all inhibit use of the crank.

Inspecting and testing before use

Initial tests

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

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: bb prior to initial use bb following 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.

Procedure

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: bb disconnect all the electrical auxiliaries of the circuit breaker (MCH, MX, XF, MN) bb remove 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: bb breaking capacities indicated on the rating plates bb identification of the control unit (type, rating) bb presence of any optional functions (remote ON/OFF with motor mechanism, auxiliaries, measurement and indication modules, etc.) bb protection settings (long time, short time, instantaneous, earth fault) bb identification 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: bb electrical auxiliaries bb terminal blocks bb connections of auxiliary circuits.

Operation

Check the mechanical operation of the circuit breakers: bb opening of contacts bb closing of contacts.

Check on the control unit

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

Inspecting and testing before use

What to do when the circuit breaker trips 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: bb depending on the type of control unit, fault diagnostics are available. See the user manual for the control unit. bb depending 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 bb Check the arc chutes (see page 40) bb Check the contacts (see page 40) bb Check the tightness of connections (see the device installation manual) bb Check 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.
