Overview
The N11MX forms part of the latest generation Navitas MX consumer unit range, combining eleven usable outgoing ways with the flexibility of the new Type 2+3 SPD system. Unlike traditional surge protected consumer units where the SPD occupies outgoing ways, the busbar adaptable Navitas SPD can be connected directly to the busbar assembly, allowing the N11MX to provide eleven usable outgoing ways as standard. For installers who prefer dedicated local overcurrent protection, every N11MX is supplied complete with the required line conductor, allowing a 32A MCB to be added if required. Manufactured from steel and finished in the distinctive Navitas textured white finish, the N11MX features a silver coated busbar, integrated locking mechanism and multiple cable entry points. Every board undergoes a 37 point quality control inspection before leaving the factory.

Why Choose Navitas
Every Navitas consumer unit is designed with installers in mind. From the silver coated busbar and integrated locking mechanism through to the flexible Type 2+3 surge protection arrangement, every detail has been engineered to simplify installation whilst maintaining the highest standards of safety and reliability.
Unlike traditional surge protected consumer units, the latest MX range provides installers with the flexibility to utilise the SPD directly from the busbar or add dedicated local overcurrent protection using the supplied line conductor. This approach helps maximise usable outgoing ways whilst allowing the installation to be configured to suit individual project requirements.
Each consumer unit undergoes a 37 point quality control inspection and is manufactured to meet the requirements of BS EN 61439, providing electricians with confidence that every assembly will perform as intended when it matters most.
