• 产品名称: CW2 Series Intelligent Universal Circuit Breaker


The circuit breaker is suitable for AC 50Hz/60Hz distribution networks with the rated working voltage of 400V, 690V and 1,000V and the rated current of 6,300A or below, and is used for distributing electric energy and protecting circuits and equipment from overload, short circuit, under-voltage, ground faults and other hazards. Due to the adoption of a multifunctional intelligent controller with accurate selective protection, it is particularly suitable for distribution networks needing power supply reliability to prevent unnecessary power failure. Circuit breakers with the rated current of 1,000A or below can be used as overload, short circuit, under-voltage and ground fault protection for motors in AC 50Hz and 400V networks, and can also be used for unfrequent starting of motors under normal conditions.
