Residual Current Protection

Residual current protection: RCCB and RCBO

Residual current protection devices monitor current imbalance and disconnect a circuit when leakage is detected. This collection brings together ABB and Schneider Electric solutions for residential, commercial and industrial distribution boards.

Choose an RCCB when leakage-current protection is required alongside a separate circuit breaker, or an RCBO when leakage, overload and short-circuit protection should be combined in one device. Compare 2-pole and 4-pole models, current ratings and 30 mA or 300 mA sensitivity. Final device selection and coordination should be confirmed by a qualified electrician.
