Moulded case circuit breaker(M1)

Product ID: GKM1

GKM1 plastic circuit breaker is a new-developed product which adopts advanced international
technology. The breaker is suited for distribution network of AC 50HZ, rated voltage 800V
(500V for GKM1-63). It is applied to distribute electric power and protect the line and the
equipment against the damage due to overload, underd-voltage and short circuit. Meanwhile,
it can also protect the motor against unfrequent start, overload, short circuit and under voltage.
This breaker has the features of small volume, high breaking capacity, short arcing
distance and ability of anti-quake. It is an ideal product for land and boating application.
This breaker conforms to IEC60947-2, GB14048-2.
