Littelfuse JLLN Series - UL Class T Fast-Acting Fuse.
Space saving POWR-TTM 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, POWR-T fuses provide fast-acting overload and short circuit protection for non-inductive circuits and equipment. Used in inductive circuits, the ampere rating of POWR-T fuses must be increased to prevent opening on inrush currents. In such instances, POWR-T fuses may provide only short circuit protection.
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 "series rated" with Littelfuse Class T fuses. Refer to panelboard manufacturers' literature for UL Listed combination of fuses and panelboards
Safety
- 200 000 A.I.R. - Reliable interruption of all overcurrents up to 200 000 amperes
- Extremely current limiting - Stops damaging short circuit current faster than any mechanical protective device
- Fast-Acting - Provides fast-acting overload protection to equipment such as variable speed drives, rectifiers and other equipment containing surge-sensitive components
