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:
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)input 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),input testing current, system adjust to setting
value
automatically.
5.Current constant current precision≤±0.5%
6.Current mutual inductor precision: 0.2 grade
7.Wave form degree of distortion≤3
8.Insulation resistance≥5MΩ
9.System error≤1%
*0.Timer resolution:1s, timer range: 1s—****9s
*1.Equipment with LCD touch screen
*2.Alarm system including coloured light, alarm button
*3.Calibration multiple will rise to 1.*5In after 1.*3In, build
form
automatically .
