Live Electrical 3 Way Horizontal Three Phase Distribution Board 100A 4P Incomer with SPD | TPNH03-100S

The Live Electrical TPNH03-100S 3 Way Horizontal Three Phase Distribution Board is a compact, high-performance power distribution solution designed for commercial and industrial installations requiring enhanced surge protection. Supplied with a 100A 4-pole switch disconnector incomer and an integrated Type 2 Surge Protection Device (SPD), this board provides safe isolation and protection against transient overvoltages.

The fitted 4-pole Type 2 SPD, rated at 20kA nominal / 40kA maximum discharge, helps protect downstream equipment from voltage spikes caused by lightning strikes and switching surges. Manufactured in accordance with BS EN 61439-1 & BS EN 61439-3, the unit delivers full compliance with current distribution board standards.

Designed with the installer in mind, the enclosure features complete shrouding of the main incomer and links for enhanced safety, a removable gland plate for easy cable entry, and earth and neutral terminals positioned adjacent to the MCBs/RCBOs, significantly reducing installation time. Keyhole wall fixing allows fast and secure mounting.

With its slim horizontal profile, the TPNH03-100S is ideal for space-conscious installations where reliable three-phase distribution and surge protection are essential.
