Audited Supplier The M1 series moulded case circuit breaker (hereinafter referred to as the circuit breaker) is one of the new circuit breakers developed by our company with international advanced design and manufacturing technology. With rated insulation voltage of 690V/1140V (500V for HKM1-63), it's suitable for circuit with frequency of AC 50Hz, rated working voltage of 690V and below (400V for HKM1-63) and rated working current up to 1600A for infrequent switching and infrequent motor startup. The circuit breaker has overload short circuit and undervoltage protection device, which can protect the circuit and power equipment from damage.
