Earth Leakage Alarm Breakers and Leakage Current Measuring Display Breakers
The additional function of monitoring of earth-leakage to MCCB or ELCB makes them to useful product.
The earth leakage alarm breaker produces an output of warning without breaking the circuit at the fault of earth leakage. The leakage current measuring display breaker measures a leak current of the circuit and indicates its value on the display. These breakers may monitor the insulation performance of the circuit.
