LMM1 moulded case circuit breaker (MCCB) is the core protection component of medium and low voltage power distribution, which is widely used in industry, commerce and large-scale buildings:The number of Poles (p) is divided into 1p (single-phase fire line) , 2p (single-phase fire + Zero) , 3p (three-phase fire line) , 4p (three-phase four-wire) , which is suitable for 230V/415V system. 4P can cut off the zero line, which is safer. The rated current (In) covers 10A-2500A, rated voltage (UE) single-phase 230V, three-phase 400V/690V,breaking capacity ICU (limit breaking, 25kA-100kA) and ICS (Operation Breaking, 25%-100% of ICU) , greater than the circuit maximum short-circuit current;The product complies with IEC 60947-2 standards
