Earth Leakage Circuit Breaker Elcb

If any current leaks from any electrical installation there must be any insulation failure in the electrical circuit it must be properly detected and prevented otherwise there may be a high chance of electrical shock if anyone touches the installation an earth leakage circuit breaker does it efficiently.

Earth leakage circuit breaker elcb. If ample voltage seems across the elcb s sense coil it will turn off the power and remain. As a general abbreviation elcb in our model name is denoted as nv. 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. Means it detects the earth leakage current and.

Earth leakage circuit breakers elcb motor protection breakers the earth leakage circuit breakers are used in applications to prevent electrical shock and electrical fires that are caused by a short circuit or overload in the control panel with an automatic shut off when leakage is detected. Current earth leakage current earth leakage circuit breaker current elcb. Earth leakage circuit breaker or elcb. It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected.

For many years the voltage operated elcb and the differential current operated elcb were both referred to as elcbs because it was a simpler name to.
