Littelfuse® POWR-GARD® JLLS300 Current Limiting Fast Acting Fuse, 300 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.
