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
