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.
