The WTPN16-125SP is a 16-way 125A three-phase distribution board designed for larger commercial and industrial installations where a high number of outgoing circuits must be managed cleanly and compliantly. Supplied as standard with a 125A 4-pole main switch, an integrated Type 2 Surge Protection Device (SPD), and a 3-pole 32A MCB, it delivers dependable power distribution straight out of the enclosure.

With 16 outgoing ways, this board is well suited to factories, multi-unit commercial premises, plant rooms, and sites running a wide range of three-phase loads. The robust IP40 steel enclosure supports structured cable management and straightforward access for inspection, testing, and future circuit expansion.
