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.
Installer Tip: A popular choice for medium commercial sites where lighting, power, and specialist circuits such as HVAC or machinery each require their own protected outgoing way.
