Elcb Breaker 3 Phase. An elcb is a specialised type of latching relay that has a building s incoming mains power connected through its switching contacts so that the elcb disconnects the power when earth leakage is detected. However some companies use the term elcb to distinguish high sensitivity current operated 3 phase devices that trip in the milliamp range from traditional 3 phase ground fault devices that operate at much higher currents.
Phase and neutral wires act as the two primary windings. They are suitable for three phase circuits and high current loads. 400a 500amp 630amp 630 amp 3p 4p 3 phase 4 pole mccb elcb 300 amp circuit breaker 3pole prices with earth leakage protection us 56 70 70 80 piece 1 piece min.
