MCCB thermal magnetic DGM2
DGM2
DGM2 series moulded case circuit breaker with the features of complete specifications, small size, high breaking capacity, short flashover,anti vibration etc. It is divided into thermal magnetic type, thermal magnetic leakage type, electronic type.There are different functions such as overload long time delay protection, short-circuit instantaneous protection, short-circuit short time delay protection, leakage protection,under-voltage protection in each series of products. Also, it can be one-piece installed with different accessories for shunt, auxiliary, alarm and communication functions. Its rated insulating voltage is 800V and it could be used as the line of the non-frequent switching in the circuit of 50/60Hz,rated working voltage up to AC 690V. Also can be used to nonmotor starting.
