The Navitas Extension Series has been developed to provide installers with a flexible and professional solution for expanding three phase distribution systems. Fully compatible with every Navitas three phase distribution board, each extension enclosure can be mounted above or below the main board to create additional space for cable entry, cable management and auxiliary equipment without compromising accessibility or internal working space.

Designed to accommodate larger submains, multiple conduits and additional control equipment, the Extension Series is ideal for housing RCDs, timers, contactors, metering equipment and other ancillary devices. By relocating terminations and auxiliary components outside of the main distribution board, installers benefit from improved cable dressing, reduced congestion and unrestricted access to protective devices, resulting in a cleaner, safer and more serviceable installation.

Manufactured from premium grade steel and finished in the same distinctive design as the Navitas three phase range, every extension enclosure features a reversible door, removable cable entry plates and a patented curved lid design. Individually inspected through our comprehensive 37 point quality control process and backed by a 10 year warranty, the Extension Series delivers the quality, flexibility and engineering professionals expect from Navitas.

I actually think this is stronger than the datasheet because it explains why someone would buy it, not just what it is. It also naturally targets valuable SEO phrases such as three phase extension enclosure, cable management, control equipment, metering equipment, contactors, timers, and three phase distribution systems.

The Navitas Extension Series is designed for commercial and industrial installations where additional space is required for cable management, control equipment or future expansion. Fully compatible with every Navitas three phase distribution board, the extension enclosure provides a clean and professional solution for accommodating larger submains, multiple conduits and high cable density installations without overcrowding the main distribution board.

It is equally suited to housing RCDs, timers, contactors, metering equipment, control gear, communication devices and other auxiliary components, making it ideal for manufacturing facilities, commercial buildings, retail developments, agricultural installations, plant rooms and infrastructure projects. By separating auxiliary equipment from the main distribution board, installers benefit from improved cable dressing, easier maintenance and unrestricted access to protective devices, resulting in a safer, more organised and future ready installation.

The Navitas Extension Series has been engineered to provide more than just additional enclosure space. Designed to integrate seamlessly with every Navitas three phase distribution board, it gives installers the flexibility to accommodate cable terminations, auxiliary devices and future modifications without compromising accessibility or the appearance of the finished installation.

Manufactured from premium grade steel and finished to the same exacting standards as the rest of the Navitas three phase range, every extension unit features a reversible door, patented curved lid design, removable cable entry plates and a robust locking system. Every enclosure is individually inspected through our comprehensive 37 point quality control process and backed by a 10 year warranty, delivering the quality, reliability and installer focused engineering professionals expect from Navitas.
