100-piece set of fast ceramic 5 x 20 mm fuses — up to 250 V Key features and benefits Complete kit of 100 fast-acting ceramic fuses, size 5 x 20 mm, rated for voltages up to 250 V. Ideal for keeping spares on hand or stocking a repair bench. Fast ceramic construction provides quick response to overcurrent events while offering improved heat and surge resistance compared with glass fuses. Helps protect sensitive electronics and prevents component damage. Wide selection of current ratings in a single pack: 0.1 A, 0.2 A, 0.3 A, 0.5 A, 1 A, 2 A, 2.5 A, 3 A, 3.15 A, 4 A, 5 A, 6 A, 7 A, 8 A, 10 A, 12 A, 15 A, 20 A, and 25 A. The 3.15 A fuse is specified as 5 x 20 mm among the set. Standard 5 x 20 mm size fits most common fuse holders and clips used in consumer electronics, appliances, and test equipment, simplifying replacements and maintenance. Consistent, reliable performance for circuit protection in systems operating at or below 250 V. Function and compatibility Function: instantaneous overcurrent protection (fast-acting) to interrupt fault currents quickly and protect downstream components. Compatibility: designed for use in any circuit or device that accepts 5 x 20 mm fast fuses and requires a fuse rated up to 250 V. Suitable for repair, maintenance, prototyping, and spare-part inventories. Performance and material Material: ceramic body improves thermal stability and arc suppression compared with glass fuses, reducing the risk of rupture or shattering under fault conditions. Performance: fast-acting characteristics make these fuses appropriate where immediate interruption of overcurrent is required to protect delicate components. Practical use scenarios Appliance repair and maintenance: replace blown fuses in household devices and small appliances that use 5 x 20 mm fast fuses and operate up to 250 V. Electronics service and prototyping: keep a range of ratings available when troubleshooting power-supply faults, testing circuits, or building prototypes that need reliable overcurrent protection. Equipment maintenance and spare parts: stock a single, compact pack to service control panels, test benches, and consumer electronics with standard 5 x 20 mm fuse holders. What you get 100 fast ceramic fuses, all 5 x 20 mm, covering the listed current ratings and suitable for circuits up to 250 V. Note These are fast-acting ceramic fuses; ensure a fast fuse is appropriate for your application (not a substitute for time-delay/slow-blow fuses where inrush currents must be tolerated).
