Residual Current Circuit Breaker with Magnetic Type - Factory Price

Product Description BYB1LE-63  series Residual current circuit breaker(without over-current protection) is suitable for the line of A and S 50/60Hz, voltage 240V(2pole)/415V(4pole), rated current up to 100A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will cut off the power rapidly to protect human safety and prevent the accident due to the current leakage. It can be used as infrequent changeover of the line in normal situation. It is applicable to industrial site, commercial site, tall building and civil house.It complies with standard of IEC/EN61008.1 and GB16916.1.Each phase of conductor at the circuit breaker passes through the zero-sequence current transformer, and the secondary side of coil connects with the electromagnetic tripper. Under normal condition, the vector sum of each phase of current passing through zero-sequence current transformer is zero. The flux of the zero-sequence current transformer is zero. And the secondary output voltage is zero and the circuit breaker doesn't zero, and the zero-sequence current transformer would produce the magnetic flux, and the secondary side of coil would output the voltage. Once the leak current increases to drive the output voltage at the secondary side to grow to certain level, the electromagnetic release would activate to drive the operation mechanism to act to break the contact that connects the power, finally to realize the leak protection.  Product Parameters  lectrical features Type(an aware form of the earth leakage sensed)BRated current In25,40,63APoles2P 4PNumber of poles versus modules2P= 4mod;4P=4 modRated voltage Ue2P:230V~ 4P:400V~Insulation voltage UI500VRated frequency50/60HzRated sensitivity IAn0.03A 0.1A 0.3ARated residual making and breaking capacity Im500(In=25-40A)630(In=63A)Short-circuit current lnc=lAc10000ASCPD fuse10000Break time under IAn≤0.1SRated impulse withstand voltage(1.2/50)Uimp6000VDielectric test voltage at and ind.Freq.for 1min2.5kVElectrical life and Mechanical life4000Pollution degree2Installation Fault current indicatorNOProtection degreeIP20Ambient temperature(with a daily average of 35 )-5~+40°ºCStorage temperature-25+70ºCTerminal connection typeCable/U-type busbar/Pin -type busbarTerminal size top/bottom for cable35mm²18-3Tightening torque3.5N*m22MountingOn DIN rail FN 60715 (35mm)by means of the fast clip deviceConnectionFrom topDetailed Photos/* 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
