Means it detects the earth leakage current and. 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. 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.
The difference between live and neutral currents is earth current in effect. A simple circuit of an earth leakage circuit breaker also called ground fault circuit interrupter is discussed in this article. You can turn off annoying electronic devices. An earth leakage circuit breaker elcb is a safety device used in electrical installations with high earth impedance to prevent shock. How to test earth leakage circuit breaker using external fault circuits. The above description is taken from here.
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. 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. It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected. One goes to the fitting earth circuit protective conductor cpc and the other to the earth rod or another kind of earth connection. Onesto krc3 230240v 25a 300ma krc3 residual current device leakage protector circuit breaker. Elcb earth leakage circuit breaker.
Earth leakage circuit breaker or elcb. The circuit once built and installed will silently monitor the health of the earth connection of your house and the connected appliance. 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. The elcb is used to protect the circuit from the electrical leakage. The device will function when the current passes through the elcb.
