NM8N moulded case circuit breaker

 

NM8N series moulded case circuit breaker is suitable for the circuit of AC50/60Hz, with rated voltage AC690V and below, DC system rated voltage DC1000V and below, and rated current of 16A and 1600A.

It can protect circuits and electric equipment against overload, short circuit or undervoltage, and can also provide protection of overload, short circuit and under voltage for infrequent start of motor.

Products have functions of power distribution protection, motor protection, residual current protection and isolation. The circuit breaker can be installed vertically, installed horizontally and can also enter the line from the bottom.
