6ka Series MCB&RCCB&RCBO Series Unified Appearance Size Circuit Breaker

Product Description6ka circuit breaker one series RCBO&MCB&RCCB assembly  :1.RCBO is mainly used in AC 50Hz(60Hz), rated voltage 230/400V, rated current 6A to 63A low voltage terminal distribution system. RCBO is equal with MCB+RCD function; It is used for electric shock protection and human indirect contact protection, electric equipment protection when human body touching electricity or electric network leak current exceeds stipulated value,and over load and short circuit protection ; It can also be a non-frequency operator in the circuit, wildly used in the residential and commercial district. It complies with standard of IEC61009-1.2.MCB is used in AC50/60Hz, rated voltage of 230V3, 4 poles 400V, rated current to 63A for overload and short-circuit protection as well as for unfrequented switching under normal case.It is used extensively for industry, commercial and household.This product conform to IEC60898 standard.3.RCCB is in conformity with the standards of IEC61008.It can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunkline.Thus it is suitable to avoid the shock hazard and fire caused by earth leakage.It can be used in circuits up to single phase 240V,three phase 415V,50 or 60Hz.  Roduct Over View:1. Provide protection against earth fault/leakage current and function of isolation2. High short-circuit current withstand capacity3. Applicable to terminal and pin/fork type busbar connection5. Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity6. Independent of power supply and line voltage, and free from external interference, voltage fluctuation. SpecificationsRCBO Standard UnitIEC/EN 61009-1ElectricalfeaturesMode  Electro-magnetic type ,electronic typeType(wave form of the earth leakage sensed) A, ACThermo-magnetic release characteristic B,C,DRated current lnA6,10,16,20,25,32,40PolesP1P+N, 3P+NRated voltage UeVAC 230, 400Rated sensitivity I△nA0.01, 0.03, 0.1, 0.3, 0.5Rated residual making and breaking capacity l△mA500Rated short-circuit capacity IcnA6000Break time under I△nS≤0.1Rated frequencyHz50/60Rated impulsewithstand voltage(1.2/50)UimpV4000Dielectric test voltage at ind.Freq for 1minkV2Insulation voltage UiV250Pollution degree 2MechanicalfeaturesElectrical life 4000Mechanical life 10000Fault current Indicator YESProtection degree IP20Ambient temperature(with daily average≤35ºC)ºC-5~+40(Special application please refer totemperature compensation correction)Storage temperatureºC-25~+70InstallationTerminal connection type Cable/Pin-type busbar/U-type busbarTerminal size top/bottom for cablemm225AWG18-5Terminal size top/bottom for busbarmm225AWG18-3Mounting On DIN rail EN 60715(35mm)by means of fast clip deviceConnection From topMCB  ModelMCBStandardIEC60898Pole1P,2P,3P,4PTripping CurveB,C,DRated Short-circuit capacity(Icn)3KA,4.5KA,6KA,10KARated Current(In)1,2,4,6,10,16,20,25,32,40,50,63ARated Voltage(Un)AC230(240)/400(415)VMagnetic releases B curve: between 3and 5 In C curve: between 5and 10In D curve: between 10 and 14In Electro-mechanical enduranceover 6000 cyclesCRCCB   StandardUnitIEC/EN 61008-1ElectricalFeatureType(wave form of the earth leakage sensed) AC,A Rated current InA16,25,32,40,63 PolesP2,4Rated voltage UeV230/400Rated sensitivity I nA0.01,0.03,0.1,0.3Insulation voltage UiV500Rated residual making andA630breaking capacity I m  Short-circuit current I cA4500/6000SCPD fuseA6000Break time under I ns
