CNC Ycm1le 2p, 3p. 4p Earth Leakage Circuit Breaker MCCB

CNC Ycm1le 2p, 3p. 4p Earth Leakage Circuit Breaker MCCBProduct DescriptionYCM1LE series earth leakage circuit breaker (herein after called circuit breaker)is applied for the power distribution network of AC 50Hz,rated current 630A.The circuit breaker can protect people against indirect contact with dangerous electric current and prevent fire disaster caused by insulation fault and single-phase ground fault. It can be used to distribute electric power and protect power equipment against overload and short circuit. The circuit breaker can change the circuit and start motor infrequently. The rated residual operating current and the maximum off-time can be adjusted on-site according to actual situation, the circuit breaker can be customized alarm function and no tripping function.The YCM1LE complies with standard of IEC60947-2TypeYCM1LE-125YCM1LE-250YCM1LE-400YCM1LE-630Frame current Inm(A)125250400630Rated current In(A)10, 16, 20, 25, 32, 4050, 63, 80, 100, 125100, 125, 140, 160180, 200, 225, 250225, 315, 350, 400400, 500, 630Pole2342343434Rated insulation voltage Ui(V)AC800Rated working voltage Ue(V)AC400Rated impulse withstand voltage Uimp(V)8000Arcing-over distance(mm)50100Breaking ability levelLMLMLMLMRated ultimate short-circuit breaking capacity Icu(kA)3550355050655065Rated working short-circuit breaking capacity Ics(kA)2225222535423542Rated residual short-circuit breaking capacity7.512.57.512.512.513.512.513.5Rated residual operating current IΔn(mA)No time-delay type30/100/500100/300/50030/100/500100/300/500100/300/500300/500/1000Time-delay type100/300/500100/300/500100/300/500300/500/1000Rated residual unoperating current IΔn(mA) 1/2 IΔn1/2 IΔn1/2 IΔn1/2 IΔnOperating performance (times)Power on1500100010001000Power off8500700040004000Total times10000800050005000Residual current protection opreating time IΔn2IΔn5IΔn10IΔnMax. breaking time(s)No time-delay type0.20.10.040.04Time-delay type0.4/10.4/10.3/10.3/1Company Profile  /* 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
