A Residual Current Breaker with Over-current (RCBO) is a comprehensive electrical safety device that combines the functions of an MCB (Miniature Circuit Breaker) and an RCCB (Residual Current Circuit Breaker). It protects circuits against overloads, short circuits, and earth leakage (shock protection), typically tripping at 30mA for residential safety.
Key Features and Functions
Comprehensive Protection: Unlike RCCBs, which only detect earth leakage, RCBOs also guard against over-cur
