China Residual Current Circuit Breaker RCCB Circuit Breaker

KNL5-63 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.

My company is a manufacturer including design, development, produce and sale, professional producing MCB, MCCB, RCCB aTool Packaging nd AC contactor etc. ProduRefrigeration Equipment ct enterprises. The company owns import and export power of self-run, expanding Europe and America, Middle East, Southeast Asia etc. Market, set a good Public praise.The company have more than 1500 workers, including senior engineer among them, engineer at inside of more than 100 technician. And then set up to cover area more than 50 acres, construct area is more than 38000 square meters of the modern industrial zone, providing with the forerunner's standard laboratory and various examination equipments.Under Korlen people to make great effort unremittingly, designed and developed by oneself, develop and produce the series of MCB, RCCB filled up local blank, attain inter-national advanced level, and acquire more than 20 national patents. The company acquires "30 strong eminent enterprises, top ten of export income, yueqing star class enterprTransmitter ise, attach importance to contract and keeps promise" title of honor for many times past years. Company still the initiative pass ISO 9001 management system verification aPrinting Materials nd 14001 environments management system verification. Our product passed quality verification of domestic and international authority organization like the CB SEMKO NF SIRIM SNI CE PCT TSE, In the meantime high breaking capacity breaker of our company in this city is the unique product which got " Yueqing famous brand product" by Yueqing people government.CertificatesFactory Lines
