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 and
Hand-held Test Kit
The Mini Test Kit and the new generation Hand-held Test Kit are portable units which require no
external power supply. Both are powered by five 9 V alkaline batteries, not supplied. These test kits are
used to check operation of the electronic trip unit and circuit breaker tripping. Connection of either test
kit is made via the test port on the front of the trip unit.
Portable Test Kit

Test Kit
The Portable Test Kit and the new generation Full-function Test Kit are calibration units. Both require a
power supply of 110 or 240 Vac, 50/60 Hz (two-position selector). These test kits are used to check the
operation of the trip unit by measuring actual trip times:
• 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
