Ev31-63-B Residual current operated circult Breaker

Construction and Feature:

◆ Elegant appearance; cover and handle in arc shape make comfortable operation. ◆ Contact position indicating window
◆ Transparent cover designed to carry label.
◆ Provides protection against earth fault/leakage current and function of isolation. ◆ High short-circuit current withstand capacity

◆ Applicable to terminal and pin/fork type busbar connection
◆ Equipped with fi nger protected connection terminals
◆ Fire resistant plastic parts endures abnormal heating and strong impact

◆ Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity.
◆ Independent of power supply and line voltage, and free from external interference, voltage fl uctuation.

Offers protection against earth leakage faults. As follow: ◆Alternating

◆Unidirectional pulsating with phase angle mode ◆Multi-frequency
◆high-frequency 1KHz
◆Direct without ripple

◆Two-phase rectified ◆Three-phase rectified
