series Intelligent type universal circuit breaker Appliance RDW1-1000 air circuit breaker, applied to power distribution network of AC50Hz, Rated voltage 400V (or 380V), Rated current from 200A to 1000A. It is mainly used to distribute electric power and protect the circuit and equipments against damages of overload, short-circuit, under-voltage and phase contact with ground this kind fault. And it also be used for circuit transfering, motor starting unfrequently and protection. This production has various intelligent protection functions, provides accurated selective protection, improves power-supply reliability to aviod unneccessary power interruption. It has isolation functions, sign is " ". This production conforms to the standard of GB14048.2 and IEC60947-2.
