Product Overview:
A new type of circuit breaker, SMS7 series has been designed and developed by our RnD team with advanced technology. SMS7 Series molded case circuit breaker, suitable for the circuit in distribution network of AC 50Hz/60Hz, rated working voltage up to 690V and rated working current up to 800A to distribute power and protect the circuit and electrical equipment against overload, short-circuit and phase loss, which can also serve as protection against infrequent starting, overload, short circuit and under voltage of the motor. It features in small compacted size, high breaking capacity and short extinguishing arc. The breaker can be installed vertically as well as horizontally.
