Description: Protect your investment with a Zephyr ceramic fast acting fuse. Many of today's electronics and home appliances are protected by fuses in case of a power spike. UL/CSA 248-14 compliant design ensures a low breaking capacity, and thus offers immediate disconnect of power should the amperage exceed that of the fuse rating. Other / inferior fast acting fuses may vary by as many as 1-2 amps, meaning your 8 amp fuse might not blow until power spikes to 10 amps. Don't let a poorly made fuse be the cause of electrical damage to your investments. Specifications: Diameter: 6mm (1/4") Length: 30mm (1-1/4") Amp Rating: 20A Voltage Rating: 250V Body Material: Ceramic Fuse Type: Fast Acting Blow (Fast Burn)
