RCBOs — Residual Current Breakers with Overload Protection

RS Electrical Supplies stocks a comprehensive range of RCBOs (Residual Current Breakers with Overload) for domestic and commercial electrical installations. RCBOs combine the functions of an MCB and RCD in a single device, providing both overload/short circuit protection and residual current protection on individual circuits.

Why Use RCBOs in Your Consumer Unit?

RCBOs offer superior circuit protection compared to traditional MCB and RCD combinations — if one circuit trips, the rest of the installation remains unaffected. This makes them the preferred choice for modern consumer unit installations under BS 7671 18th Edition. Our range includes Type A and Type AC RCBOs in a variety of current ratings and sensitivities, from leading brands including BG, Fusebox, and Hager — suitable for use in their respective consumer unit ranges.

Can't find the RCBO you need? Contact us — we can source most circuit protection products on the market.
