20 Amp Quick Acting Current Limiting Class J Fuse (600V)

Note: Image displayed may not represent actual product. Features Single-element, current-limiting fuses provide superior short-circuit protection. Protects low interrupting capacity circuit breakers. Limits the short-circuit current to meet the interrupting capacity requirements of existing equipment. On older systems available short-circuit current may exceed the interrupting capacity of the circuit breakers, fuses can be installed in series with existing equipment. Well suited for lighting and heating circuits and other non-inductive loads. Provides component short-circuit protection in compliance with NEC® 110-10, where protection devices shall clear a fault without “extensive damage” to the circuit components. High interrupting rating helps meet the requirements of future system expansion and the increases in available utility short-circuit current. Fuses can easily be selectively coordinated when sized per published coordination ratios.
