Mini Type A RCBOs – Compact 1 Module Protection
Mini Type A RCBOs combine residual current and overcurrent protection in a compact 1 module format, making them ideal where consumer unit space is limited. These devices are designed for modern installations where electricians need the right protection characteristics without giving up valuable board space.
With Type A residual current detection and high immunity performance, they are well suited to consumer units serving modern electronic loads, upgraded domestic circuits, and specialist applications where nuisance tripping needs to be kept under control.
Quick answer: A mini Type A RCBO gives you combined MCB and RCD protection in a space-saving single-module device. They’re a strong choice for modern consumer units, especially where board space is tight and Type A protection is preferred.

Why Choose a Mini Type A RCBO?
A mini Type A RCBO is designed for installers who need proper circuit protection in a tighter board layout. By combining MCB and RCD protection in a compact single-module device, these RCBOs help free up space in consumer units without sacrificing practical protection performance.
What Makes a Mini RCBO Different?
The main advantage is size. A compact RCBO takes up less room than older or bulkier formats, which makes a real difference on smaller consumer units, retrofit jobs, and board upgrades where spare ways are limited.
Where Mini Type A RCBOs Are Commonly Used
- Smaller consumer units – where every module matters
- Garage units and outbuildings – where compact protection helps maximise available ways
- Board upgrades – especially when replacing devices in tighter layouts
- Modern electronic circuits – where Type A detection is better suited to the load profile
- Specialist circuits – including applications linked to EV chargers or heat pump boards where the wider design calls for Type A protection
How to Choose the Right Mini Type A RCBO
- Current rating – match the device to the circuit design and load
- B or C curve – B curve suits many standard domestic circuits, while C curve may be better for circuits with higher inrush
- Board space – mini formats are ideal where outgoing ways are at a premium
- High immunity performance – useful where nuisance tripping could otherwise become a problem
Featured Mini Type A RCBOs
- Mini Type A RCBO – B Curve – compact high immunity protection for standard circuit applications.
- Mini Type A RCBO – C Curve – useful where higher inrush characteristics need to be considered.
Mini Type A RCBOs vs Standard Type A RCBOs
The key difference is physical format. A mini Type A RCBO is chosen primarily for its compact size, while a standard Type A RCBO page may include a broader mix of device styles, breaking capacities, and form factors. If you specifically need a 1 module Type A RCBO, this is the right collection to target.
FAQs on Mini Type A RCBOs
What is a mini Type A RCBO?
A mini Type A RCBO is a compact protective device that combines MCB and RCD functions in a single-module format and detects AC plus pulsating DC residual current.
Why choose a compact RCBO?
Compact RCBOs help save space inside the consumer unit, which is useful on smaller boards or upgrades where spare ways are limited.
What’s the difference between B and C curve mini RCBOs?
B curve devices are commonly used on standard circuits, while C curve devices are generally selected where higher inrush currents are expected.
Are mini Type A RCBOs the same as Type B RCBOs?
No. This collection is for Type A RCBOs. If users are landing here for Type B terms, that likely needs clearer separation elsewhere in the site structure and copy.
