Webt. e. An earth-leakage circuit breaker ( ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent installations instead use ... WebThe RCBO is a current sensing component that can automatically disconnect and measure the circuit whenever the current exceeds the rated sensitivity, or a fault happens in a connected circuit. This device is purposed to protect one from the risk of electrical shocks, firesand electrocution. It can also assist in sudden earth faults.
