Read more about three-phase boards
A three-phase board (also called a 3 phase fuse board or 3 phase consumer unit) is designed to distribute incoming three-phase power across multiple circuits. These boards are commonly used in industrial switchgear installs, where balancing load and ensuring fault protection is critical.
Typical use cases include motor circuits, HVAC plant, lighting control, and renewable system integration with heat pump and EV-ready systems.
All units are manufactured in line with BS EN 61439 and suitable for installs that must meet 18th Edition Amendment 2. See our returns policy for hassle-free support.

What Is a Three Phase Board?
A three phase board, sometimes called a fuse board or consumer unit, splits incoming three-phase supply into manageable circuits. This ensures loads are balanced, fault protection is applied, and your installation meets UK wiring standards.
Where to Use Three Phase Fuse Boards
- Commercial and industrial premises with high load demand
- Motor circuits, HVAC, or plant equipment
- Lighting and power separation for safety
- Renewables and hybrid installs needing surge and PME protection
Standards & Compliance
All our three-phase boards and accessories are supplied to BS EN 61439 and IEC standards, with clear labelling for straightforward installation. Devices comply with 18th Edition Amendment 2, covering mandatory surge protection and PME safety requirements.
