MCB Standard Tester (MCB12)

タイトルまたは説明

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:

1.Power voltage: **0V(1±*0%)  *0Hz

2.Capacity: *2kVA, *2 stations, 1.2kVA per station, output current

independently and set parameters in each station respectively

3.Max output current for two stations: AC（1A～**0A）(two gears current

range:****0A, **0A display pratical current directly with full scale,no

need to conversion) testing current, system adjust to setting value

automatically.

4.Max output current for ten stations: AC（1A～**0A）(four gears current

range:*5A, *0A, **0A display pratical current directly with full scale,no

need to conversion), testing current, system adjust to setting value

automatically.

5.Current constant current precision≤±0.5%
