Buying guide: MCB, RCCB and RCBO: what each one does

  1. An MCB trips on overload and short circuit. It protects the cable.

  2. An RCCB trips when current leaks to earth. It protects people from electric shock.

  3. An RCBO combines both in one module for a single circuit.

  4. Ratings: amps (e.g. 6A, 16A, 32A), poles (1P, 2P, 4P) and, for RCCBs, sensitivity (e.g. 30 mA, 100 mA).
