Description
The Knightsbridge 13A fused spur unit in gunmetal finish pairs a 2.5mm ultra-low profile flat plate with a matching fuse carrier, creating a unified metal surface with minimal projection from the wall. Certified to BS 1363-4, the unit provides switched isolation and overcurrent protection for permanently connected appliances such as boilers, water heaters, extractor fans and kitchen appliances rated up to 13A.
Designed for residential, commercial and light industrial installation, the fused spur fits a standard 25mm minimum back box depth and uses premium-grade steel construction with a dark gunmetal finish that pairs with contemporary, industrial and minimalist interiors. The flat plate design sits nearly flush with the wall surface, giving a lower profile than traditional raised or domed plates. A built-in gasket behind the faceplate improves dust resistance and provides a cleaner edge seal against painted or tiled wall surfaces.
The 87.5mm square faceplate matches the footprint of standard single-gang accessories, allowing the fused spur to sit alongside switches and sockets in the same range without mismatched proportions. The gunmetal finish is applied to steel rather than plastic, giving a harder-wearing surface than polymer alternatives and a consistent tone across multiple units installed in the same room. The matching fuse holder integrates into the faceplate without contrasting plastic components visible when the unit is mounted.

Frequently Asked
What is a fused spur used for?
A fused spur provides switched isolation and overcurrent protection for permanently wired appliances such as boilers, extractor fans, water heaters and kitchen appliances. It allows the appliance to be switched on and off without needing to unplug it, and the fuse protects the appliance circuit separately from the ring main.
What fuse rating does it take?
The unit accepts a standard BS 1362 13A cartridge fuse. The fuse should be rated to match the appliance load — typically 3A for low-draw appliances like extractor fans or 13A for higher-draw appliances like water heaters. The fuse is not included and must be purchased separately.
What back box depth is required?
A 25mm minimum back box depth is needed for safe installation. The 2.5mm projection of the faceplate means the total wall projection is approximately 27.5mm once fitted.
Does it have a neon indicator?
No. This model does not include a neon indicator light. If you need visual confirmation that the spur is powered, Knightsbridge produces versions of this fused spur with neon indicators in the same finish range.
