Product information

Description

Legrand 406278 is an electrical distribution board accessory sized 86 × 98 × 26 mm supplied as a single unit. It is designed to mount on the left-hand side of compatible modular devices and to provide a clean interface for remote tripping, busbar insertion and simple joining with the main device without tools. The accessory is intended for use with miniature circuit breakers, residual current breakers with overcurrent protection, residual current devices and remote trip isolating switches in residential and commercial distribution panels.

It is compatible with push-button remote tripping via a normally open contact and allows tool-free mechanical joining to the associated main device, reducing installation time. The component is suitable for systems operating from low voltage up to 415 V AC and occupies a single module width for space-efficient panel layouts.
