At the forefront of electrical distribution innovation, BG Electrical has once again raised the standard with the launch of its Fortress range of Single Module SPD RCBO Consumer Units. Designed to provide electricians and installers with an optimal balance of protection, space efficiency, and build quality, this new range is a game-changer for single-phase residential and commercial installations alike.
The line-up features five new models:
CF9MS6 – 6-way board
CF12MS9 – 9-way board
CF16MS13 – 13-way board
CF19MS16 – 16-way board
CF22MS19 – 19-way board
Each model combines all the proven durability and functionality that professionals expect from BG’s Fortress series, now with a clever enhancement – a single module SPD (Surge Protection Device). This innovation frees up valuable space within the consumer unit, translating to an extra usable way in each board, without compromising on safety or protection.
The Power of a Single Module SPD
Traditional dual-module SPDs, while effective, consume significant board space – an increasingly limiting factor for modern installations that require more circuits and flexibility. BG’s newly integrated single module SPD addresses this head-on by condensing full surge protection capabilities into one compact unit.
This not only ensures compliance with the latest 18th Edition wiring regulations (BS 7671), particularly in environments where overvoltage protection is mandated, but it also maximises the board’s circuit capacity, a critical benefit for both installers and end-users seeking futureproofed solutions.
Previous single-mod SPDs have existed but have required the addition of a 32a MCB, so again, the system would take up two usable ways, but BG have changed the technology, incorporating everything required into this new single-mod SPD.
In practical terms, that’s one more usable way in every board – an advantage that can make a real difference in complex or space-limited installs.
Fortress Build Quality – Engineered for Professionals
The BG Fortress range has long been celebrated for its robust steel construction, neat design, and installer-friendly features – and the new single-module SPD boards are no exception.
Each unit is engineered with:
- High-integrity neutral bars to accommodate clean and organised terminations
- Earth bars with ample terminal spacing, ensuring ease of wiring
- Removable gland plates on the top, bottom and rear for flexible cable entry
- Knockouts in a variety of sizes, further simplifying site adaptations
- Pre-fitted DIN rails and cable clamps, reducing installation time
The overall finish of the Fortress boards maintains the clean, minimalist aesthetic that professionals appreciate, suitable for both exposed and concealed locations.
Compatible with the BG Compact RCBO Range
One of the key strengths of this new Fortress range lies in its compatibility with the BG Compact RCBO range, a suite of devices specifically developed to make the best use of the available space in modern boards.
Installers can choose from:
CUCRB – B Curve Compact RCBOs
CUCRC – C Curve Compact RCBOs
CUCRBDPA – B Curve Compact Bi-Directional RCBOs
6A examples given in the links above - Both B and C curve RCBOs are available in 6A, 10A, 16A, 20A, 32A & 40A with the addition of a 25A option in the Bi-Directional collection.
Their compact, single-module format aligns perfectly with the single module SPD layout of the new Fortress boards. This synergy ensures full circuit protection, reduces the need for extra enclosure space, and delivers a streamlined look and feel to the finished board.
The inclusion of Bi-Directional RCBOs also opens up the boards to safe use in installations with renewable energy sources, such as solar PV systems, reflecting BG’s forward-thinking approach and commitment to energy efficiency.
And of course, there is a full blank available - the CUA19
Space, Safety and Simplicity – All in One
What makes the BG Fortress Single Module SPD RCBO Boards particularly appealing is the balance they strike between innovation and practicality. With the compact SPD saving a full module’s width, professionals gain:
- Greater circuit flexibility in the same footprint
- Reduced need for additional enclosures or split configurations
- Simplified layouts and neater installations
- Faster install times, aided by intuitive design and clear labelling
This makes them ideal not only for new builds and major refurbishments, but also as upgrade options for installations needing surge protection retrofits or expanded capacity under the latest wiring regulations.
Ideal for Modern Demands
In an age where homes and businesses are filled with sensitive electronics and smart devices, reliable surge protection is no longer optional – it's essential. BG’s single module SPD provides that protection efficiently, allowing electricians to deliver future-ready installs without compromise.
Whether you’re outfitting a large property with the CF22MS19 or need a more compact solution like the CF9MS6, there’s a Fortress model tailored to your needs – all with premium build quality, intelligent space-saving design, and full compatibility with BG’s acclaimed RCBOs.
Discover the full range now and upgrade your installs with the smarter, more spacious choice – the BG Fortress Single Module SPD RCBO Boards.
