Navitas 4 Way 125A TPN Type B Three Phase Distribution Board | NTP4M-B

125A 4 Way Three Phase Distribution Board for Commercial & Industrial Installations

The Navitas NTP4M-B is a premium 125A three phase distribution board designed for commercial and industrial installations requiring 4 TPN outgoing ways. Built on the same high-quality platform as the Navitas SPD range, this version is supplied without a factory-fitted Surge Protection Device (SPD), providing installers with the flexibility to specify surge protection separately where required.

The enclosure has been intelligently designed to accommodate an optional Type 2 SPD via a dedicated protective device without sacrificing outgoing ways or requiring a different enclosure. Featuring a heavy-duty 125A four-pole switch disconnector, removable gland plates, integrated DIN rails and compatibility with the Navitas Extension Board System, the NTP4M-B delivers a robust, installer-friendly solution for modern three-phase electrical installations.

Manufactured from durable steel with a premium black finish, every Navitas distribution board undergoes a comprehensive 37-point quality inspection and is backed by a 10-year manufacturer's warranty.
