RCBOs – Residual Current Circuit Breakers with Overload Protection provide essential protection for modern electrical installations by combining RCD and MCB functions in a single device. This collection is suited to domestic and light commercial use where individual circuit protection, fault isolation and space saving within consumer units are important.

Our range of RCBOs is suitable for trade electricians, installers and knowledgeable DIY customers working to current wiring standards. These devices are commonly chosen for new builds, consumer unit upgrades and targeted circuit protection where isolating a single circuit is preferred over a full board shutdown.

RCBOs are widely used on circuits such as sockets, lighting, kitchen appliances, showers and outdoor supplies. By protecting against earth faults, short circuits and overloads in one unit, they help maintain safety while reducing inconvenience when a fault occurs on a specific circuit.

When selecting an RCBO, it is important to consider factors such as current rating, tripping characteristics and the correct residual current rating for the application. Physical size and format should also suit the consumer unit in use, as well as the specific circuit requirements set out in the installation design.

This collection includes RCBOs designed for compatibility with common UK consumer units. Always ensure you are matching the RCBO to the correct board type and manufacturer specifications. If you need other circuit protection devices, you may also wish to explore our wider range of protective devices available across the site.
