Ycw1 Acb 1600A 1500A Air Circuit Breaker

Ycw1 Acb 1600A 1500A Air Circuit BreakerProduct DescriptionYCW1 series intelligent air circuit breakers (hereinafter called ACB) are applied for the network circuit of AC 50Hz, rated voltage 400V, 690V and rated current between 630A and 6300A. Mainly used for distributing energy and protecting the circuit and power supply device against short-circuit, undervoltage, single-phase ground fault, etc. The ACB has intelligent protection function and the key parts adopt intelligent release. The release can make the accurate selective protection, which can avoid cutting off the power and improve the reliability of power supply.The products conform with IEC60947-1,IEC60947-2 standards.YCW1-1000 series intelligent air circuit breakers(hereinafter called ACB) are applied for the network circuit of AC 50Hz,rated voltage 400V,690V and rated current up to 1000A.Mainly used for distributing energy and protecting the circuit and power supply device against short-circuit,undervoltage,single-phase ground fault etc. The ACB have intelligent protection function and the key parts adopt intelligent release. The release can make the accurate selective protection, which can avoid cutting off the power and improve the reliability of power supply.The products confirm with IEC60947-2,GB14048.2.Type YCW1-2000YCW1-3200YCW1-6300Pole 3P, 4P3P, 4P3P, 4PUsing category BBBRated current InA630, 800, 10001250, 1600, 20002000, 2500, 30004000, 5000, 6300Rated frequencyHz505050Rated operation voltage UeV400, 690400, 690400, 690Rated insulation voltage UiV800800800Arcing distancemm000Rated impulse withstanding voltage UimpV800080008000Rated operation short circuit breaking capacity Ics (O-t-CO)400VkA4065100660VkA405065Rated limiting short circuit breaking capacity Icu (O-t-CO)400VkA6580120660VkA506575Rated short time withstanding current Icw (O-t-CO, AC400V 0.4S)400VkA405080Operation lifePer hourtimes202010Electricaltimes1000500500Mechanicaltimes1000050005000Full breaking time ms20~3020~3020~30Full closing time ms55~7055~7055~70Power consumption3PW360120020004PW45017502300Resistance of each poleFixed typeμΩ119-Draw out typeμΩ201410Dimensions (L×W×H)3P fixed typemm362×323×402422×323×402 3P draw out typemm375×461×452435×471×452 4P fixed typemm457×323×402537×323×402 4P draw out typemm470×461×452550×471×452 Approximate weight3P fixed typekg4155 3P draw out typekg71952454P fixed typekg51.565-4P draw out typekg86115260Overload protection dataOverload protectionYCW1-2000~6300Adjust scope Ir1 (0.4-1)In (pole difference 2%)1.05 Ir1h≥2h non-tripping1.3 Ir1h≤1h tripping1.5 Ir1s1530601202404802.0 Ir1s8.416.933.767.5135270Accuracy%±15Short circuit, short time delay Adjust scope Ir1 Ir2 (0.4-15)In (pole difference 2%)Delay time tr2ms100, 200, 300, 400Accuracy%±15Short circuit, instantaneous  YCW1-2000YCW1-3200YCW1-6300Adjust scope Ir1 Ir3 1In-50kA1In-75kA1In-100kAAccuracy%±15±15±15Load monitoring outputYCW1-2000~6300Load adjust scope Ic1 (0.2-1)In (pole difference 2%)Delay time tc1 tr1×0.5Load adjust scope Ic2 (0.2-1)In (pole difference 2%)Delay time tc2 tr1×0.25 (anti-time limit)Accuracys60 (set time limit)%±10Company 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
