Jzw-2000/3 3p/4p Acb Vacuum Circuit Breaker

Product DescriptionSONTUOEC JZW-2000/3  3P/4P ACB 1600A Vacuum Circuit Breaker Fixed Intelligent Air Circuit BreakerGeneralJZW-2000/3 series JZW-2000/3 universal circuit breaker(hereinafter referred to as breaker)is suitablefor the circuit of AC 50Hz with rated voltage 400V, 690V and rated current up to 6300A.It is mainly used to distribute electric energy and protect circuits and power-supplyequipment from overload, under-voltage, short-circuit and single-phase earthing. withintelligentized and selective protection functions, the breaker can improve the reliabilityof power supply, and avoid unnecessary power failure. The breaker is applicable forpower stations, factories, mines(for 690V) and modern high-buildings, especially for thedistribution system of intelligentized building. This breaker conforms to IEC60947-2 andGB14048.2. The whole series have past CCC certification.3.Feature of Intelligent Air Circuit Breaker(ACB)Type  JZW -2000/3Pole  3P, 4PUsing categary  BRated current In A630, 800, 1000, 1250, 1600, 2000Rated frequency Hz50/60Rated operation voltage Ue V400 690Rated insulation voltage Ui V800Arcing distance mm0Rated impulse withstanding voltage Uimp V8000Rated operation short circuitbreaking capacity Ics(O-t-CO-t-CO)400Vka50690Vka40Rated limiting short circuitbreaking capacity Icu(O-t-CO)400Vka80690Vka50Rated short circuit closing capacity Icm400Vka176690Vka105Rated short time withstandingcurrent Icw(O-t-CO,AC400V 0.4s)400Vka50Operation lifeper hourTimes20 ElectricalTimes1000 MechanicalTimes10000Full breaking time ms20~30Full closing time ms55~70Power consumption3PW360 4PW450Resistance of each poleFixed typeμ Ω11 Draw out typeμ Ω20Dimensions(L*W*H)3P fixed typemm362*323*402 3P draw out typemm375*461*452 4P fixed typemm457*323*402 4P draw out typemm470*461*452Approximate weight3P fixed typekg41 3P draw out typekg71 4P fixed typekg51.5 4P draw out typekg86/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
