Littelfuse® POWR-GARD® JLLS250 Current Limiting Fast Acting Fuse, 250 A, 600 V AC/300 V DC, 20/200 kA Interrupt, T Class, Cartridge Body
Space saving Class T fuses are the most compact fuses available in ratings above 30 A - less than one-third the size of comparable Class R fuses. When rated in accordance with the NEC, Class T fuses provide Fast Acting overload and short circuit protection for non-inductive circuits and equipment. Used in inductive circuits, the ampere rating of Class T fuses must be increased to prevent opening on inrush currents. In such instances, Class T fuses may provide only short circuit protection.

Edison's UL Class J fuse products are offered in both Dual-Element Time-Delay (JDL) and Fast-Acting (JFL) types. Both types have 200,000 amp interrupting rating at 600Vac RMS Sym amps. Their small physical size and high performance characteristics makes Class J fuses ideal for any space-limited applications. Edison's JFL fuses are best suited for the protection of non-inductive loads such as resistive heating and lighting circuits.
