Description

The JLLS series fast-acting fuses are the most compact fuses available in ratings above 30 amperes — less than one-third the size of comparable Class R fuses. The JLLS fuses are used for short-circuit protection of drives and surge- sensitive components. When rated in accordance with the NEC, these fuses provide fast-acting overload and short-circuit protection for non-inductive circuits and equipment. Main switches containing JLLS fuses can be used to provide compact protection for meter stacks. It should be noted that molded case circuit breaker load centers and panelboards have increased interrupting ratings when “series rated” with Littelfuse Class T fuses. JLLS fuses are available in non-plated and silver plated terminations. Features & Benefits FEATURES BENEFITS 200,000 AIR Safety feature providing reliable interruption of all overcurrents up to 200,000 A Current-limiting Reduces damage caused by heating and magnetic effects of short- circuit currents; extends the equipment’s lifecycle Fast-acting Provides fast short-circuit response for equipment requiring fast overload protection POWR-GARD® technology Ensures quality overcurrent protection Compact size More efficient use of available space – typical three-pole Class T fuse blocks require less than 50% of the panel area required for Class R fuse blocks Functional protection When used as input or output fuses for surge-sensitive components, they can prevent opening of expensive semiconductor fuses that protect individual components
