Description

The Knightsbridge 3A fuse is a BS 1362 certified cartridge fuse rated at 3A for 240V 50Hz mains circuits. Each fuse measures 6.35mm diameter by 25.4mm length, fitting standard UK 13A plug fuse holders. The pack contains 10 fuses supplied on a blister card with euro slot for retail display.

Used in 13A plugs for low-draw appliances such as table lamps, televisions, radios, small kitchen appliances and chargers, the 3A rating provides circuit protection up to 720W on 240V. The ASTA approval confirms compliance with British Standard 1362, the specification for fuses used in UK domestic plugs and adaptors. The ceramic body is filled with silica sand to suppress arcing when the fuse element melts under overload.

The 10-pack format suits trade electricians, facilities managers and households keeping spare fuses for multiple appliances. Each fuse is marked with the 3A rating and the BS 1362 certification symbol in red print on the ceramic body, making identification straightforward when replacing a blown fuse in a plug.

Frequently Asked

What appliances use a 3A fuse?

3A fuses are used in 13A plugs for appliances drawing up to 720W on 240V mains, including table lamps, floor lamps, televisions, radios, DVD players, set-top boxes, phone chargers and small kitchen appliances like kettles under 720W. Higher-draw appliances such as vacuum cleaners, irons and most kitchen appliances require 13A fuses.

Are these compatible with all UK 13A plugs?

Yes. The 6.35mm x 25.4mm dimensions are the BS 1362 standard size for all UK 13A domestic plugs and fused adaptors. The fuse fits any plug with a removable fuse holder.

What does BS 1362 certification mean?

BS 1362 is the British Standard for cartridge fuses used in 13A plugs and adaptors. Certification to BS 1362 confirms the fuse meets safety requirements for breaking capacity, temperature rise, mechanical strength and marking. ASTA approval provides independent third-party verification of compliance.

How do I know when a fuse has blown?

When a fuse blows, the appliance stops working and the fuse element inside the ceramic body will be visibly broken or blackened. Remove the fuse from the plug and hold it up to light — if the metal strip running through the centre is intact, the fuse is still good. If the strip is broken or missing, replace it with a new 3A fuse.
