Moulded Case Circuit Breaker

Used for preventing personal electric shock, equipment electric leakage protection and preventing ire accident resulting from the ground fault  

  current generated by the damaged insulation, SDCM2 breaker is applicable to the low voltage power system of which the AC is 50Hz, the rated 

  current is 20A~800A, the rated insulation voltage is 1000V and the rated operational voltage is 690V or lower. 

● SDCM2 series breaker uses smart overcurrent release constituted by microprocessors. The rated current and overcurrent protective characteristics  

  are adjustable, better matching with the distribution line or motor load, used for protecting overload and short circuit of line, motor and other 

  equipment. Under the normal circumstance, the breaker can be used as infrequent conversion of line and infrequent start of motor.
