Manufactures the most trusted dependable earth leakage relays for more than 15 years and they are time tested h series earth leakage are different from other normal leakage relays. Normally earth fault relay earth leakage circuit breaker and ground fault circuit interrupter etc. One terminal of the relay coil is connected to the metal body of the equipment to be protected against earth leakage and other terminal is connected to the earth directly.
Are used to restrict the fault current. Earth fault relay efr it is a safety device used in electrical installations with high earth impedance. Check my new video https youtu be eqnenms wrk earth leakage relay setting earth leakage relay diagram earth leakage relay for single phase earth leakage. If ample voltage seems across the elcb s sense coil it will turn off the power and remain.
It detects small stray voltages on the metal enclosures of electrical equipment. Current earth leakage current earth leakage circuit breaker current elcb. An elcb is a specific type of latching relay that has a structure s incoming mains power associated through its switching contacts so that the circuit breaker detaches the power in an unsafe condition the elcb notices fault currents of human or animal to the earth wire in the connection it guards. The working principle of voltage elcb is quite simple.
