Glass Fuse 20 MM 1 AMP

A 20mm mini glass fuse rated at 1 amp, the standard quick-blow type rather than slow-blow. Glass fuses of this size are found in older cars and classic vehicles, in accessory plugs and chargers, and in all sorts of audio, workshop and household equipment, so it is worth keeping a few spares in the glovebox or toolbox.

• Type: quick-blow glass fuse (not slow-blow)
• Rating: 1 amp
• Voltage rating: 250V
• Size: 5mm diameter x 20mm long

Check the rating printed on the fuse you are replacing or in the equipment's handbook before ordering, and always replace a fuse with one of the same amperage. Sold individually, so order the number you need.

Practical tip: if a new fuse blows straight away, there is a fault in the circuit, not a bad fuse. Never fit a higher-rated fuse or wrap the old one in foil; find the short first, or you risk melting the wiring.
