A residual current device is the second protection layer in a board: it protects people against earth leakage, while the MCB protects cables and equipment.
Choosing between RCCB and RCBO directly affects board layout and cost; both families are listed here with official data.
Selection notes CHECK
- A main RCCB with RCBOs on sensitive circuits is the common layout.
- Match pole count to single-phase or three-phase supply.
- Decide on fault-type indication before choosing a model.
