A Residual Current Operated Circuit Breaker (RCBO) is a critical safety measure when protecting electrical circuits. The 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.
After knowing the RCBO meaning, you can continue to read this article to uncover more regarding the principles and advantages. This device is purposed to protect one from the risk of electrical shocks, firesand electrocution. It can also assist in sudden earth faults. The installation of an RCBO ensures that a circuit trips immediately and protects you from electric shock.
The test circuit included in the residual current device ensures that the RCBO reliability is tested. After you push the test button, the current begins to flow in the test circuit since it established an imbalance on the neutral coil, the RCBO trips, and supply disconnects and checked the reliability of RCBO.
