MBM1 Moulded Case Circuit Breaker

 

Applications:
The breaker is mainly used in distribution network of AC50Hz or 60Hz,rated voltage up to 690V,rated working current up to 800A to distribute electric power and to protect the line and the equipment from being damaged due to overload,short circuit and under-voltage.It can also be used for unfrequent motor start and for motor overload,short circuit and under voltage protections.
