MCCB Circuit Breakers 63A-800A 2p 3p 4p 400V/690V Electric Moulded Case Circuit Breakers

Product DescriptionThe 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.The circuit breaker is classified into four types based on its rated ultimate short-circuit breaking capacity (Icu): C type (low breaking type), L type (standard type), M type (medium breaking type) H type (high breaking type). This circuit breaker has the characteristics of small volume, high breaking capacity, short arc (zero arc for some specifications) and vibration resistance, making it an ideal product for land and ship use.
