40A 63A 80A 2Pole 4Pole Type B RCD RCCB Residual Current Circuit Breaker

Type B RCCBs, in addition to normal AC, can detect high frequency AC and pure DC earth leakage currents. Reducing the risk of fire and/or electrocution through automatic disconnection of the electrical supply relies on the selection of the correct type of RCCB EKL1-63B.

Construction and Feature

Elegant appearance; cover and handle in arc shape make comfortable operation.
Contact position indicating window
Transparent cover designed to carry label.
In case of overload to protect circuit, RCCB handle trips and stays at central position, which enables a quick solution to the faulty line. The handle cannot stay in such position when operated manually. Provides protection against earth fault/leakage current and function of isolation.
High short-circuit current withstand capacity EKL1-63B
Applicable to terminal and pin/fork type busbar connection
