125A TPN distribution boards with SPD for commercial, industrial, and larger three-phase installs where reliable load distribution and surge protection are both required. These boards are supplied with a 4-pole main switch and integrated Type 2 surge protection, making them a practical choice for modern 3 phase distribution setups.
Available in 4 to 24 way formats, this range is suited to electricians and contractors specifying robust 3 phase distribution boards for workshops, plant areas, commercial units, and other demanding applications.
Quick answer: A 125A TPN board with SPD is used where you need a three-phase distribution board with a strong incomer rating and built-in surge protection. They are commonly specified for commercial and industrial installs where multiple outgoing circuits and a 3 phase supply are involved.
Each board in this collection is built around a 125A 4-pole incomer and factory-configured surge protection arrangement, helping speed up specification and installation. Depending on the model, boards are designed for straightforward fitting and future expansion, with compatible accessories available where extra capacity is needed.

Select the board from the load schedule, incoming supply and required outgoing circuits. The 125A headline rating, number of ways and integrated surge protection must all coordinate with the actual supply capacity, fault level and protective-device system.
Choose from compact to larger boards by counting outgoing circuits, pole requirements and sensible spare capacity—not just the number of current loads.
Integrated Type 2 surge protection provides a tidy board configuration where suitable. Confirm its system arrangement, backup protection and replacement details.
Conversion kits, extension boxes and spreader boxes can support the installation, provided they are compatible with the selected board system.
