CM1 series plastic case circuit breaker (hereinafter referred to as circuit breaker) is a circuit breaker developed by our company with manufacturing technology. Its rated insulation voltage is 800V, suitable for AC 50 Hz, rated working voltage 690V and below, rated working current from 10a to 1250A circuit for infrequent switching and motor starting (gnm1-800 and gnm1-1250 without motor protection).
CM1E series electronic plastic case circuit breaker (hereinafter referred to as circuit breaker) is suitable for AC 50 Hz / 60 Hz, with rated insulation voltage of 800 V, rated working voltage of 690 V and below, rated working current of 16 ~ 800 a for infrequent switching and motor starting. The circuit breaker has the functions of overload long time delay inverse time limit, short circuit short time delay inverse time limit, short circuit short time delay definite time limit, short circuit instantaneous and under voltage protection, residual current protection (optional) and open phase protection (optional), which can protect the line and power supply equipment from damage. The circuit breaker has complete protection characteristics, can improve power supply reliability and avoid unnecessary power failure.
CM1L series plastic case circuit breaker with residual current protection (referred to as residual current circuit breaker) is one of the residual current circuit breakers designed and developed by our company. It is used in circuits with AC 50 Hz, rated voltage to 690 V and rated current from 16 A to 800 a. Its main function is to provide indirect contact protection for people with fatal risk of electric shock.
