Cjm2-63-1 3p MCB Miniature Circuit Breaker with CE

  Product DescriptionCJM2-63-1 Type Miniature circuit breakers (MCBs) ensure electrical safety in homes and similar situations, such as offices and other buildings as well as for industrial applications by protecting electrical installations against overloads and short circuits. Once a fault is detected, the miniature circuit breaker automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. Warranting reliability and safety for people and assets, MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection. normally the rated current is 1,2,3,4,6,10,16,20,25,32,40,50,63A and rated voltage is 230/400VAC. frequency is 50/60Hz. according to IEC60898/EN60898 standards.Construction and Feature·High short-short capacity 6KA.·Designed to protect circuit carrying big current up to 63A.·Contact position indication.·Used as main switch in household and similar installation. Product Parameters  StandardIEC/EN 60898-1Pole No1P,1P+N, 2P, 3P,3P+N,4PRated voltageAC 230V/400VRated Current(A)1A,2A,3A,4A,6A,10A,16A,20A,25A,32A,40A,50A,63ATripping curveB, C, DRated short-circuit capacity(lcn)6000ARated frequency50/60HzRated impulse withstand voltage Uimp4kVConnection terminalPillar terminal with clampMechanical life20,000 CyclesElectrical life4000 CyclesProtection degreeIP20Connection capacityFlexible conductor 35mm²Rigid conductor 50mm²InstallationOn symmetrical DIN rail 35mmPanel mountingOverload Current Protection Characteristics  TestTripping TypeTest CurrentInitial StateTripping timeor Non-tripping Time ProvisioraTime-delay1.13InColdt≤1h(In≤63A)t≤2h(ln>63A)No TrippingbTime-delay1.45InAfter test at
