Diameter: 10 x 38 mm Available current ratings: 0.5A, 1A, 2A, 4A, 5A, 6A, 8A, 10A, 16A, 20A, 32A Fuse type: fast acting impact (fast burning) Key benefits Rapid protection: the fast-acting (fast burning) construction interrupts short circuits and overcurrent conditions quickly to minimize damage to sensitive components. Standard form factor: the 10 x 38 mm size fits common panel and inline fuse holders, making it an easy drop-in replacement or spare part. Flexible protection levels: available in a wide range of current ratings so you can choose the correct rating for the circuit, from low-current electronics up to higher-power circuits. Simple maintenance: straightforward installation and replacement reduces downtime when a fuse operates. What this fuse does and why you need it Protects circuits from short circuits and sustained overcurrent by opening the circuit quickly when current exceeds the fuse rating. Prevents costly damage to boards, power supplies and connected devices by acting as a sacrificial safety device. Allows system designers and technicians to match protection precisely to component and wiring limits by selecting the appropriate amperage. Important attributes Size: 10 x 38 mm cylindrical fuse — compatible with standard 10×38 holders and clips. Current ratings: 0.5A, 1A, 2A, 4A, 5A, 6A, 8A, 10A, 16A, 20A, 32A (select required rating for the circuit). Type: Fast acting impact (fast burning) — designed for quick interruption of overcurrent events. Function: Overcurrent and short-circuit protection for electrical and electronic equipment. Compatibility and installation notes Fits any device or holder designed for 10 x 38 mm fuses. Confirm the holder accepts a fast-acting fuse and the correct current rating for your circuit. Replace a blown fuse only with the same size and the same current rating and fuse type to maintain intended protection. Verify system voltage and interrupting requirements in the device documentation before replacement. Typical applications Power supplies and chargers: fast interruption protects sensitive DC regulators and downstream electronics from short circuits. Test and laboratory equipment: quick acting protection for instruments and bench supplies where rapid fault clearing prevents component damage. Industrial controls and lighting circuits: used in panels and inline holders to protect control electronics and lighting drivers from overcurrent events. Usage tips Choose the lowest amperage that will carry normal operating current without nuisance blowing, but high enough to tolerate inrush where appropriate. For circuits with significant inrush (motors, large transformers), confirm that a fast-acting fuse is suitable; time-delay fuses may be required in those cases. Keep spare fuses of the correct rating on hand to minimize downtime. Safety reminder Always power down and isolate circuits before inspecting or replacing fuses. Replace with identical size and rating to ensure correct protection.
