Overview
N3MX 3 Way Consumer Unit with Type 2+3 SPD
The Navitas N3MX forms part of the latest generation MX consumer unit range, developed to provide installers with greater flexibility without sacrificing valuable outgoing ways.
At the heart of the N3MX is the latest Navitas Type 2+3 Surge Protective Device. Unlike traditional consumer units where surge protection often reduces the available outgoing ways, the new busbar adaptable SPD can be connected directly to the busbar assembly, allowing the board to provide three fully usable outgoing ways as standard.
For installers who prefer dedicated local overcurrent protection, every N3MX is supplied complete with the required line conductor, allowing a 32A MCB to be installed for SPD protection if required. This gives installers the flexibility to configure the board to suit project requirements whilst retaining the simplicity of a complete out of the box solution.
Manufactured from steel and finished in the distinctive Navitas textured white finish, the N3MX combines practical installation features including a silver coated busbar, integrated locking mechanism, multiple cable entry points and a top mounted gravity hinge lid. Like every consumer unit within the Navitas range, each assembly undergoes a 37 point quality control inspection before leaving the factory.
The compact dimensions of the N3MX make it particularly suitable for smaller installations, garage supplies, workshops, outbuildings and dedicated circuits where installation space may be limited but performance and reliability remain essential.
