125A 3 Phase Distribution Board – 8 Way (WTPN08-125SP)

The WTPN08-125SP is an 8-way 125A three-phase distribution board designed for commercial and industrial installations that require a higher number of outgoing circuits without moving to a full-size panel. It is supplied as standard with a 125A 4-pole main switch, an integrated Type 2 Surge Protection Device (SPD), and a 3-pole 32A MCB, ensuring safe and compliant distribution from the outset.

With 8 outgoing ways, this model suits workshops, retail spaces, plant rooms, and small industrial units running multiple three-phase loads. The robust IP40 steel enclosure provides long-term durability, while compatibility with our MCBs and RCBOs allows straightforward circuit configuration and future adjustments.

What type of installs suit an 8-way three-phase board?

The 8-way model is well suited to medium-sized commercial units, retail spaces, workshops, and light industrial sites with multiple three-phase circuits.

Does this board include surge protection?

Yes. All WTPN boards are supplied with an integrated Type 2 SPD as standard.

Is a 3-pole MCB included with this board?

Yes. The WTPN08-125SP includes a 3-pole 32A MCB as part of the standard configuration.

Can this replace a 4 or 6-way board?

Yes. If future expansion is expected, the 8-way board provides additional capacity without moving up to the larger 12 or 16-way enclosures.

Which breakers are compatible with this board?

This board accepts our full range of 6kA MCBs and RCBOs without modification.
