10kA RCBOs – Type A High Breaking Capacity
Our 10kA Type A RCBOs combine overload, short circuit, and earth leakage protection with a 10kA breaking capacity – making them ideal for commercial and industrial installs where fault levels are higher than in standard domestic setups. Fully compliant with 18th Edition Amendment 2, these RCBOs cover the full 6A–50A range in both B and C curves.

Built as Type A devices, they reliably detect AC and pulsating DC residual currents. Their 10kA breaking capacity ensures safe disconnection in higher fault current environments such as three-phase distribution boards, EV charging systems, and heat pumps.
- 10kA breaking capacity – for commercial & industrial boards
- Type A protection – detects AC & pulsating DC leakage
- 6A–50A range – covers most final circuit requirements
- B & C curve options – for domestic and higher inrush loads
- 18th Edition compliant – required for EV, solar & inverter installs
All RCBOs are UK stocked for next-day delivery and backed by a 2-year manufacturer warranty. See our returns policy for full details.

Choosing the Right 10kA RCBO
A 10kA RCBO is the right choice when installing in environments where prospective short-circuit currents are higher than 6kA. They’re commonly required in commercial distribution boards, industrial systems, and large-scale EV/heat pump installs.
Key Considerations
- Breaking capacity – 10kA vs 6kA, depending on board rating and fault level.
- Curve type – B curve for standard domestic circuits, C curve for higher inrush loads.
- Current rating – available from 6A through to 50A.
- Compliance – all units meet BS EN 61009 and 18th Edition regs.
Featured 10kA RCBOs
- Type A RCBO – 10kA WRT Range – 6–50 A, B & C curves, bi-directional for EV & solar.
- High Immunity 10kA RCBO – resists nuisance trips in EV and renewable installs.

FAQs
When do I need a 10kA RCBO?
Use a 10kA device when installing into boards with a fault level above 6kA – typically commercial or three-phase systems.
Are these still Type A devices?
Yes – they combine Type A earth-leakage detection with 10kA breaking capacity.
Do I need high immunity?
High immunity versions are recommended for EVs, heat pumps or inverter-driven systems where background leakage may cause false trips.
