Sale Residual current Circuit Breaker RCCB
|Unit Price:||1 USD|
|Min. Order:||1 Bag/Bags|
|Place of Origin:||Wenzhou; Zhejiang; China|
Model No.: KNL1-63
The RCCB can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunk, thus, it is suitable to avoid the shock hazard and fire caused by earth leakage.
KNL1-63 Residual Current Circuit Breaker
1.Provide protection against earth fault/leakage current and function of isolation
2.High short-circuit current withstand capacity
3.Applicable to terminal and pin/fork type busbar connection
4. Equipped with finger protected connection terminals
5.Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity
6.Independent of power supply and line voltage, and free from external interference, voltage fluctuation.

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 zreo, 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.
