Fuse 5x20mm 1A

A 1A glass cartridge fuse in the standard 5 x 20 mm size used in equipment, power supplies and PCB fuse holders. The glass body lets you see at a glance whether the element has blown, which saves testing. Choose the rating to sit above your circuit's normal working current but below what the wiring and components can survive - fitting a larger fuse because the correct one keeps blowing removes the protection entirely and is how equipment fires start. Glass body shows at a glance whether it has blown; Standard 5 x 20 mm size fits common holders; Protects equipment and wiring from overload; Inexpensive insurance against costly damage
