The WTPN12-125SP is a 12-way 125A three-phase distribution board designed for commercial and industrial installations that require a higher circuit count with room for structured distribution. 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 compliant and dependable power distribution straight out of the enclosure.

With 12 outgoing ways, this board is well suited to plant rooms, workshops, retail units, and light industrial sites running multiple three-phase circuits across lighting, power, and dedicated equipment. The durable IP40 steel enclosure supports tidy cable management and straightforward access for inspection, maintenance, or future circuit additions.
