NS moulded case circuit breaker (called circuit breaker for short hereinafter) is one of newly-developed circuit breakers designed and made by our company, its design embodies updated craft limited-current principle as well as making craft, with compact structure, full modulization, high disjunction, zero flying arc, and other features. Its insulation voltage is 750V, suitable for wires with AC 50Hz, rated working voltage of 690V and below, rated working current of 630A, to work as unfrequent start. Circuit breaker has overload protection, short circuit protection and owe-voltage protection device, can prevent wires and electric source equipments from being damagedIt also can be used as direct starter to start the motor and as a switch to changeover the circuit under normal conditions.
