Littelfuse JLLS060 Class T Industrial Cartridge Fast-Acting 60A 600VAC 300VDC 20000A Interrupting Rating

The JLLS060 from Littelfuse is a cutting-edge Class T fuse designed to deliver exceptional protection against short circuits and overloads. This fast-acting fuse offers an impressive interrupting rating of 20,000 amperes at 300V DC, assuring reliable interruption of all overcurrents up to 200,000 A.I.R., thus safeguarding critical equipment. Its current limiting capability not only enhances safety by stopping damaging currents more efficiently than traditional mechanical protective devices, but also allows for the use of less costly, readily available equipment. Incorporated into molded case circuit breaker load centers and panelboards, the JLLS060 significantly increases interrupting ratings when “series rated” with other Littelfuse components, providing versatile protection for individual electric services and meter stacks. Ideal for surge-sensitive components such as variable speed drives and rectifiers, this fuse helps prevent costly damage to semiconductor devices. With its compact design, the JLLS060 requires less panel area compared to Class R fuse blocks, making it a smart choice for modern industrial applications.
