JLLS Series - UL Class T Fast-Acting Fuse

Brand: Littelfuse, Inc

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.

For motor and general purpose circuits where space is not critical, we recommend POWR-PRO™ JTD_ID Indicator series, LLNRK/LLSRK series, or FLSR_ID Indicator series.
