Use and scope of application

NMCM1 series plastic case circuit breaker (hereinafter referred to as circuit breaker), rated insulation voltage is 800V, suitable for AC 50Hz, rated working voltage to 690V, rated working current from 10A to 1250A in the distribution network circuit, used to distribute the line and The power supply unit is protected from damage such as overload, short circuit, and under voltage. At the same time, it can also be used as infrequent starting and overload, short circuit and under voltage protection of the motor. The installation dimensions are the same as those of Chint's molded case circuit breakers NM1 and Mitsubishi NF, so the installation has excellent interchangeability. Optional transparent case.

The circuit breaker standard: GB14048.2-2008, EC60947-2 has passed the national mandatory CCC certification.
