The Knightsbridge Metal Clad range is a heavy duty selection of switches and sockets with a durable, powder coated metal finish. The metal clad wiring accessories are designed for use in rugged environments such as warehouses, workshops and garages where standard plastic sockets could potentially be damaged. The M6300N is a switched fused spur with neon indicator (FCU) and is supplied with a metal clad backbox. As standard, the backbox benefits from multiple 20mm knockouts. The fused spur is fully certified to BS 1363-4.
