The Navitas NTP4 Series is a 125A three phase distribution board designed for commercial and industrial installations requiring four TPN outgoing ways. Available with or without factory fitted Type 2 surge protection, every board is built on the same premium platform. The integrated SPD solution is pre fitted as standard, requiring no additional assembly on site, while its innovative design preserves all outgoing ways by mounting directly to the busbar assembly. For installers preferring dedicated overcurrent protection, the SPD can also be connected via a local protective device without sacrificing flexibility or requiring a different enclosure.

Overview
Designed around the needs of modern commercial installations, the NTP4 Series provides a practical solution where a smaller three phase distribution board is required without compromising on build quality or installation flexibility.
Featuring a heavy duty 125A four pole incomer, removable gland plates, integrated DIN rails and compatibility with the Navitas extension board system, the enclosure has been engineered to simplify installation whilst providing excellent cable management and future expansion options. Every board is individually inspected through our comprehensive 37 point quality control process and backed by a 10 year warranty.
