Detailed Description: Littelfuse Powr-Gard® JLLS Series Class T Fuse is uniquely designed for variable speed drives, rectifiers and other surge-sensitive equipments. Compact fuse provides reliable fast-acting overload and short-circuit protection with dependable current limiting. It measures 2-61/64 Inch x 3/4 Inch. It is rated at 600/300 VAC/VDC, 80 Amps. Cartridge blade fuse must be boosted to prevent nuisance opening on inflow currents. Economical power fuse can be easily mounted on a holder. Fast blow fuse has knife blade termination style. Class T fuse is UL and CSA approved.

| Catalog Description | JLLS UL CLASS T FAST-ACTING FUSE 80A. Space-saving Class T fuses are the most compact fuses available in ratings above 30 amperes ù 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-PROÖ JTD_ID Indicator series, LLNRK/LLSRK series, or FLSR_ID Indicator series. Applications: Protection of individual electric services and meters. Main switches containing Class T fuses may be used to provide compact protection for meter stacks. Molded case circuit breaker load centers and panelboards have increased interrupting ratings when ôseries ratedö with Littelfuse Class T fuses. Refer to panelboard manufacturersÆ literature for UL Listed combination of fuses and panelboards. Series ratings up to 200,000 amperes are available. Space Saving: Typical three-pole Class T fuse blocks require less than 50percent of the panel area required for Class R fuse blocks. Switch enclosures, fuse pullouts, and other equipment using Class T fuses are often correspondingly more compact. Safety: 200,000 A.I.R. ù Reliable interruption of all overcurrents up to 200,000 amperes. Extremely current limiting ù Stops damaging short circuit current faster than any mechanical protective device. Fast-Acting ù Provides fast-acting overload protection to equipment such as variable speed drives, rectifiers and other equipment containing surge-sensitive components. Longer Equipment Life: Current limiting design greatly reduces damage to equipment caused by heating and magnetic effects of short circuit currents. Economical: Extremely current limiting design often permits use of readily available, less costly equipment. Used as input or output fuses for surge-sensitive components, such as variable speed drives and rectifiers, fast-acting Class T JLLS fuses may prevent opening of expensive semiconductor fuses protecting individual components. |
