This FuseBox Compact RCBOs Explained guide covers the compact and mini RCBO options available for compatible FuseBox consumer units. Compact FuseBox RCBOs are designed to save space inside the board while still combining overload, short-circuit and residual current protection in one device.
These devices can be useful where wiring space is limited, especially in modern consumer unit installations using multiple RCBO-protected circuits. Before ordering, always check the board type, busbar arrangement, device size, current rating, tripping curve and whether the installation requires a bidirectional RCBO.

What Exactly Is an RCBO?
An RCBO (Residual Current Breaker with Overcurrent) is a protective device that combines two functions:
- Residual current detection (like an RCD).
- Overcurrent detection (like an MCB).
Instead of using separate devices, an RCBO performs both jobs in one.
Why FuseBox Compact RCBOs Were Developed
As consumer units become crowded with SPDs, AFDDs, and multiple RCBOs, space inside the board is at a premium. FuseBox compact RCBOs solve this problem by offering:
- Slimline design.
- Same protection levels as a standard RCBO.
- Type A compliance for modern loads like EV chargers and LED lighting.
Standard vs Compact FuseBox RCBOs
Both types comply with BS 7671, but the choice depends on your install:
- Standard size RCBOs: widely used, slightly larger.
- Compact RCBOs: slimmer footprint, ideal for space-limited boards.
Many electricians mix both within the same FuseBox consumer unit.
Bi-Directional FuseBox Compact RCBOs
FuseBox now produce bi-directional compact RCBOs, which can be installed either way on the busbar. Benefits include:
- Faster installation.
- Reduced risk of fitting errors.
- Same compact footprint as the slimline range.
FuseBox Consumer Units, Kits & Accessories
A compact RCBO is only as effective as the board it’s fitted into. That’s why so many electricians choose FuseBox consumer units.
For extra convenience, we also supply FuseBox consumer unit kits, which include the board, RCBOs, blanks, and accessories in one package.
