RCBO (Residual Current Breaker with Over-Current) – A breaker that combines the functionality of an MCB and an RCD into one. As these breakers only take up one space in a consumer board, this means they won’t take up too much space, allowing you to combine them with MCBs and RCDs in a household consumer unit.
