The WTPN08-125 is an 8-way 125A three-phase distribution board, built for commercial and industrial sites that require more outgoing circuits than the 4 or 6-way options. Fitted with a 125A 4-pole main switch and integrated Type 2 SPD, it provides safe, compliant distribution for medium-sized installs where reliability and expansion capacity are essential.
This model offers 8 outgoing ways, making it ideal for workshops, retail spaces, or small factories with multiple three-phase loads. The robust IP40 steel enclosure ensures durability and simple servicing, while compatibility with our full range of MCBs and RCBOs makes circuit configuration straightforward.
Installer Tip: The 8-way unit is a common choice for medium commercial sites where lighting, power, and specialist circuits (such as HVAC or machinery) all need their own protected ways.
