Electronic trip unit test kits

Mini test kit

The two test kits presented below are compatible with COMPACT

and

MASTERPACT

circuit breakers.

Tests performed by test kits are only functional tests designed to electrically test the

operating integrity of the trip unit, the flux shifter and the mechanical operation of the

circuit breaker. Tests are not designed to calibrate the circuit breaker.

Mini test kit

The mini test kit is a portable unit requiring no external power supply (five 9 V

alkaline batteries, not supplied), used to check operation of the electronic trip unit

and circuit breaker tripping. It connects to the test connector on the front of the trip

unit.

The calibration test kit is used to check the operation of the trip unit by measuring

the actual trip time:

■ At 1.5 x Ir (for long-time protection);

■ At 15 x Ir (for short-time protection);

■ At 0.8 x In (for ground-fault protection).

Required power supply: 110 or 240 Vac, 50/60 Hz (2-position selector).
