Cjm9-63 1p AC230/400V High Capacity 6ka MCB Miniature Circuit Breaker

Product DescriptionCJM9-63 Type miniature circuit breaker(MCB)is mainly used for protection against overload and the short circuit under the AC 50Hz/60Hz, rated voltage 230V/400V, and rated current from 1A to 63A. It also can be used for non-frequent on-and-off switch operations under normal circumstances.Construction and Feature ·Protection against both overload and short circuit ·High short-circuit capacity ·Easy mounting onto 35mm DIN rail·Terminal electric devices shall be mounted on Din rail of TH35-7.5D type.·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.Normal Service Condition·Altitude above sea level less than 2000m; ·Ambient temperature -5~+40, average temperature not exceeding +35 within 24 hours; ·Relative Humidity not exceeding 50% at maximum temperature +40 higher relative humidity allowed at lower temperature. For example, relative humidity 90% allowed at +20; ·Pollution class: II (means generally only non-electricity conducting pollution is considered, and also considers temporary electricity conducting pollution occasionally caused by condensed dew);·Perpendicular installation with allowed tolerance  5. Product Parameters  StandardIEC/EN 60898-1Rated Current6A,10A,16A,20A,25A,32A,40A,50A,63ARated Voltage230/400VAC(240/415)Rated Frequency50/60HzNumber of Pole1P,2P,3P,4P(1P+N,3P+N)Module size18mmCurve typeB,C,D TypeBreakering capacity4500A,6000AOptimumoperating temperature-5ºC to 40ºCTerminal Tightening torque5N-mTerminal Capacity(top)25mm²Terminal Capacity(bottom)25mm²Electro-mechanical endurance4000cyclesMounting35mm DinRailSuitable BusbarPIN BusbarOverload Current Protection CharacteristicsTestTripping TypeTest CurrentInitial StateTripping timeor Non-tripping Time ProvisioraTime-delay1.13InColdt≤1h(In≤63A)t≤2h(ln>63A)No TrippingbTime-delay1.45InAfter test at
