Wylex NHXLB40 40A MCB SP Type B

Wylex 10A MCB, compatible with Wylex NM consumer unit range. Wylex NHXLB miniature circuit breakers detect overcurrents via overloads and fault currents and interrupt the supply to prevent damage to the installation. Wylex miniature MCB’s require less space therefore providing more wiring space for the installer making the whole process easier and quicker. During installation resistance testing live and neutral conductors do not have to be disconnected, this saves landlords time and money testing installations during occupancy voids.

Now available with the same sized matching NHXS miniature RCBOs that have an increased level of safety by including a switched neutral as standard, reducing installation and testing times therefore bringing costs down. A faulty or damaged circuit is fully isolated by disconnecting the live and neutral conductors. Healthy circuits remain in service, only the faulty circuit is switched off. This avoids danger and prevents inconvenience in the event of a fault (now required by regulation 314.1).
