ASKM3 Molded Case Circuit Breaker for General Protection

ASKM3 thermomagnetic molded case circuit breaker(hereinafter referred to as MCCB) is a new type of circuit breaker designed and developed by ourcompany using international advanced technology. The rated insulation voltage of MCCB is 1000V. MCCB is suitable for the distribution network of AC50/60Hz, rated voltage 690V and below, rated current 10A- 1250A. MCCB can distribute power and protect circuits and power equipment against faultslike overload, under-voltage, short. circuit and under-voltage. MCCB can also be used for infrequent switching of lines and infrequent starting ofmotors. The products have the characteristics of small volume, high breaking capacity, short flying arc, vibration resistant, etc. The whole series haveisolation function.

FAQ

1、What accessories can be installed?

Alarm contact, shunt release, auxiliary contact, undervoltage release, electric operating mechanism, manual operating mechanism, machine operating mechanism

2、What are the reasons for frequent tripping?

Possible causes include: excessive load, circuit short, unstable voltage, internal fault or improper trip setting.

3、Can this type of MCCB be used in DC circuits?

Currently only available for AC400/415V, AC660/690V.

4、What should I do if the MCCB can't close the brake?

Check whether overload or short circuit is not ruled out.

Check whether the operating mechanism is stuck.

Check whether the undervoltage trip and shunt trip are operational.

Check that the auxiliary contacts and interlocking mechanisms are correct.
