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.
