General Purpose Fuses  
JLLN/JLLS POWR-T™ Class T Fuses  
300/600 VAC • Fast-Acting • 1 – 1200 Amperes  
Applications  
Littelfuse Class T fuses can be used in applications that require fast-  
acting protection, such as equipment containing variable speed drives,  
rectifiers, and other surge-sensitive components. Main switches  
containing Class T fuses may be used to provide protection to individual  
electric services and meter stacks. Molded case circuit breaker load  
centers and Panelboards also will have increased interrupting ratings  
when “series rated” with Class T fuses.  
Features/Benefits  
Space-Saving – Switch enclosures, fuse pullouts, and other equipment  
using Class T fuses are usually more compact. Typical three-pole Class  
T fuse blocks require less than 50% of the panel space required by  
similar Class R blocks.  
Longer Equipment Life and Increased Safety – Class T fuses provide  
fast, reliable protection against overcurrents up to 200,000 amperes.  
Extremely current-limiting design minimizes the damaging heating and  
magnetic effects caused by short-circuit currents.  
Optional Mounting Types – In addition to the Class T dimensions,  
Littelfuse offers select ratings with PC board mounting tabs for specialty  
applications. PC board mount versions are UL Recognized. Contact the  
factory for more information.  
Space saving POWR-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®, 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 in-rush currents.  
In such instances, POWR-T fuses may provide only short-circuit protection.  
NOTE: JLLN Class T 300 volt fuses are UL Listed for circuits not  
exceeding 300 volts to ground. However, since UL does not include  
testing 300 volt Class T fuses on 277/480 volt three-phase bolted faults,  
Littelfuse does not recommend using 300 volt Class T fuses where  
phase-to-phase voltage exceeds 300 volts.
