Choosing the Right Mini Type A RCBO
Mini RCBOs are a smart choice where space is limited but compliance cannot be compromised. Use them in garage boards, small consumer units, or retrofit jobs where every module counts.
Key Considerations
- Module size – 1-module width, leaving more usable ways in the board.
- Curve type – B curve for standard domestic circuits, C curve for higher inrush loads.
- High immunity – avoids false trips from harmless leakage currents.
- Load rating – available from 6A to 40A to suit lighting, socket, and appliance circuits.
Featured Mini RCBOs
- Mini Type A RCBO – B Curve – compact high immunity device with options from 6A to 40A for domestic installs.
- Mini Type A RCBO – C Curve – ideal for higher inrush loads and commercial boards, with ratings from 6A to 40A.
Trust & Compliance
Every mini Type A RCBO is BS EN 61009 certified, tested for safety and long-term performance, and fully 18th Edition compliant. With fast UK shipping and a 2-year warranty, you can specify with confidence.
FAQs
Why choose a mini RCBO?
Mini RCBOs are only 1 module wide, so they save board space compared to 2-module alternatives.
Are these suitable for EV and heat pump circuits?
Yes – as Type A devices with high immunity, they’re designed for EVs, heat pumps, and inverter-driven loads.
What’s the difference between B and C curves?
B curve is best for domestic circuits with low inrush, while C curve handles higher inrush loads typical of motors or commercial equipment.
