RCBOs – Combined Circuit Protection
Shop RCBOs for domestic and commercial boards, including Type A, mini, high-immunity, 10kA, EV and multi-pole options.
An RCBO combines overcurrent and residual-current protection for an individual circuit. Select the current rating, trip curve, breaking capacity and residual-current type from the installation design and connected equipment.
Quick guide: RCBOs can limit the disruption caused by a circuit fault because each outgoing circuit has its own residual-current and overcurrent protection. Correct device and consumer-unit compatibility remain essential.
- Type A RCBOs: common options for modern electronic loads
- Mini RCBOs: compact single-module formats for compatible boards
- High-immunity RCBOs: designed to reduce unwanted tripping in suitable applications
- 10kA and multi-pole RCBOs: specialist breaking-capacity and conductor configurations

Selecting an RCBO for the Circuit
An amp rating alone is not enough. Coordinate the RCBO with design current, conductor capacity, fault current, load inrush, residual-current waveform and the consumer-unit assembly. Follow the equipment and board manufacturer’s instructions.
Type A & Mini RCBOs
Type A devices respond to AC and pulsating DC residual current. Mini formats save module space, but must still be approved for the selected assembly.
High-Immunity RCBOs
Designed for improved resistance to certain transient or electrically noisy conditions. They can help reduce unwanted operation where correctly specified.
10kA, EV & Multi-Pole
Higher breaking capacity, EV-labelled and multi-pole products address distinct design requirements. Confirm the actual fault level and equipment requirements rather than selecting by label alone.
Specification Checklist
- Rated current: coordinate with design current and conductor capacity.
- Trip curve: select around inrush and fault-disconnection requirements.
- Breaking capacity: verify against prospective fault current.
- Residual-current type: match the connected equipment and expected waveform.
- Assembly compatibility: confirm manufacturer approval, terminals, busbar and module width.
