The above description is taken from here. An earth leakage circuit breaker elcb is a safety device used in electrical installations with high earth impedance to prevent shock.
Earth Leakage Circuit Breaker Amp Residual Current Device
Earth leakage circuit breaker connection diagram. Elcb earth leakage circuit breaker. A simple circuit of an earth leakage circuit breaker also called ground fault circuit interrupter is discussed in this article. The connection to the earth rod is accepted through the earth leakage circuit breaker by linking to its two earth terminals. The earth circuit is adapted when an elcb is used. Voltage elcb contains relay coil which it being connected to the metallic load body at one end and it is connected to ground wire at the other end. Earth leakage circuit breaker or elcb.
Onesto krc3 230240v 25a 300ma krc3 residual current device leakage protector circuit breaker. It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected.

Voltage base elcb voltage elcb is a voltage operated circuit breaker. The circuit once built and installed will silently monitor the health of the earth connection of your house and the connected appliance. As you can see from the above earth is included but isnt needed and some devices down provide a thru going connection for earth.
Thus the earth circuit permits. One goes to the fitting earth circuit protective conductor cpc and the other to the earth rod or another kind of earth connection. When someone gets an electric shock then this circuit breaker cuts off the power at the time of 01 secs for protecting the personal safety and avoiding the gear from the circuit against short circuit and overload. The difference between live and neutral currents is earth current in effect. The device will function when the current passes through the elcb. How to test earth leakage circuit breaker using external fault circuits.
How earth leakage circuit breaker work working of elcb working of rccb an eclb is one kind of safety device used for installing an electrical device with high earth impedance to avoid shock. Means it detects the earth leakage current and. 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 installationan earth leakage circuit breaker does it efficiently. You can turn off annoying electronic devices. The elcb is used to protect the circuit from the electrical leakage.
