5x20mm

Littelfuse makes several types of 5x20 mm fuses to provide supplemental overcurrent protection to circuits and other electronic devices such as transient voltage surge suppressors. We offer the cartridge fuses with glass or ceramic bodies. Some of the fuses are fast-acting, and others incorporate Slo-Blo® technology to deliver time-delayed circuit protection. A few change color when they blow. You will find our 5x20 mm fuses protecting uninterruptible power supplies, medical equipment, smart meters, LCD screens, and integrated circuits in household appliances.
