What is an RCBO and How Does it Work?
An RCBO (Residual Current Breaker with Overcurrent protection) is an electrical protection device that combines the functions of a residual current device and a circuit breaker in a single unit. This means it protects against both earth leakage faults and overcurrents, ensuring comprehensive safety in electrical installations.
The RCBO operates by detecting current differences between the live and neutral wires. If a leakage occurs, the RCBO disconnects the power supply to prevent accidents such as electric shocks or fires.
