Read more about three-phase consumer units
A three-phase board (also called a 3 phase fuse board or 3 phase consumer unit) distributes incoming three-phase supply into multiple protected circuits. They’re essential for commercial and industrial installations where high electrical loads must be balanced safely.
Typical setups include motor circuits, HVAC systems, lighting distribution, and renewable integration. Our three-phase range includes surge protection devices, PME fault detection units, and heat pump consumer units – all compliant with BS EN 61439 and 18th Edition Amendment 2.

What Is a Three Phase Board?
A three-phase board – often referred to as a 3 phase fuse board, consumer unit, or panel board – is designed to split an incoming three-phase supply into safe, manageable circuits. Each circuit is protected by fuses or breakers, preventing overload and ensuring compliance with UK wiring regulations.
Where Three Phase Consumer Units Are Used
- Commercial premises with high load demand
- Industrial environments running motors, plant, or HVAC
