Littelfuse® JLLS025 POWR-GARD® JLLS Current Limiting Fast Acting Fuse, 25 A, 600 VAC/300 VDC, 20/200 kA Interrupt, Class T

Space-saving Class T fuses are the most compact fuses available in ratings above 30 amperes - 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.
