Three phase boards and accessories for commercial, industrial, and higher-load electrical installations. This collection includes 3 phase distribution boards, three phase surge protection, PME fault detection devices, and related accessories used to build, protect, and expand three-phase systems properly.
Whether you're specifying a 3 phase fuse board, adding surge protection, or sourcing supporting components for a larger install, this range is built around the products electricians and contractors regularly need for dependable three-phase distribution.
Quick answer: A three phase board distributes incoming power across multiple circuits in commercial and industrial installations. This collection covers the core boards plus the surge, PME, and accessory products often specified alongside them.
A three phase board, sometimes searched for as a 3 phase fuse board or three phase distribution board, is used where a single-phase consumer unit is not suitable for the size, load profile, or equipment involved. These boards are common in workshops, commercial units, plant areas, agricultural buildings, and industrial settings where balanced load distribution and robust circuit protection matter.

A three phase board is used to distribute power safely across multiple circuits where the installation has a three-phase supply. Compared with a standard domestic consumer unit, these boards are designed for larger loads, more demanding equipment, and installations where circuit separation, load balancing, and accessory compatibility are more important.
A three phase board, also called a 3 phase distribution board or sometimes a 3 phase fuse board, takes an incoming three-phase supply and divides it into protected outgoing ways. These boards are commonly used in commercial premises, workshops, industrial sites, and any environment where a single-phase setup would be too limited.
These products are commonly specified alongside our 125A TPN boards with SPD, 3 phase surge protection devices, PME fault detection, and broader three phase boards and protection collections.
What is a three phase board used for?
A three phase board is used to distribute power across multiple circuits in installations with a three-phase supply, typically in commercial, industrial, or larger specialist environments.
Is a three phase board the same as a 3 phase fuse board?
In many searches, yes. People often use terms like three phase board, 3 phase fuse board, and three phase distribution board to describe closely related products or board types.
Can I add surge protection to a three phase board?
Yes, many three-phase installs use SPD protection either built into the board or specified alongside it, depending on the product and installation design.
Are these the same as domestic consumer units?
Not usually. Three phase boards are generally used on larger or more demanding systems than a typical single-phase domestic consumer unit.
