The WTPN16-125 is a 16-way 125A three-phase distribution board designed for industrial, commercial, and large residential projects requiring extensive outgoing circuit capacity. Supplied with a 125A 4-pole main switch and integrated Type 2 Surge Protection Device (SPD), it delivers safe, regulation-compliant power distribution for complex sites.
With 16 outgoing ways, this board is ideal for larger offices, warehouses, or multi-unit residential properties. The robust 1.2mm steel IP40-rated enclosure ensures durability and longevity, while full compatibility with our MCBs and RCBOs makes circuit protection and future expansion straightforward.
Installer Tip: Choose the 16-way board for sites where multiple distribution circuits are needed – such as separate building zones, HVAC, and EV charging bays – all requiring their own protected ways.

What kind of sites use the 16-way three-phase board?
It’s designed for larger commercial and industrial projects such as warehouses, production areas, and multi-floor office spaces.
Is surge protection included?
Yes – a Type 2 SPD is pre-installed as standard.
Why choose this over the 12-way board?
The 16-way model provides four additional circuits, giving more room for separation of loads like HVAC, lifts, and dedicated machinery feeds.
Does it work with your MCBs and RCBOs?
Yes – it accepts our complete range of 6kA MCBs and RCBOs without modification.
