Durite 20mm automotive radio glass fuses with nickel-plated brass caps from Arc Components Ltd. Used for component surge protection and usually found attached by clips onto a control circuit PCB, mounted in a fusebox on a distribution panel, or singularly in a holder (with flying cables or cable entry) as an electric wiring in-line fuse. Born from a need to replace fuse wire holders (awkward to replace and unprotected from the heat build-up and blow radius) with an easily changed solution, the glass fuse fast became an industry favourite and is still widely used. The section covers the most common amperages 1A, 2A, 3A, 5A, 8A, 10A, 15A and 20A, along with inline fuse holders. The packs are supplied in 10's for infrequent use and 50's for service engineers, service centre workshops and manufacturing production line.
