Omega Series Earth Leakage circuit breaker (ELCB) without over current protection conforms to the standards of GB16916.1, IEC1008, and BS 4293 etc. It is used in the circuit of AC 50~60Hz, single phase 240V, three phases 415V in industrial & mining enterprises, commercial buildings and housing for protection of personal electric shock hazard and electric equipment and for unfrequented switchover of circuits under normal conditions
Construction and Feature:
-Provides protection against earth fault/leakage current and function of isolation.
-High short-circuit current withstand capacity
-Application to terminal and pin/fork type bulbar connection
-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 internal interference voltage fluctuation.
