MCB Standard Tester (MCB12)

Product Description

Equipment function:

    The tester is used for miniture circuit breaker time-current

characteristic.Input all poles with 1.*3ln current up to required time from

the cold, no trip, then higher current to 1.*5ln steadily within 5s, MCB

should trip within required time.Tester judge qualified situation , reserve

result and build database automatically.

Tester parameters:
