Littelfuse JLLS080 Class T Fast-Acting 80A 600VAC 300VDC Knife-Blade Bolt-In

The JLLS080 - JLLS Series from Littelfuse exemplifies compact efficiency with its innovative design tailored for modern electrical systems. Utilizing a three-pole Class T configuration, these fuse blocks occupy significantly less panel area compared to traditional Class R options, allowing for more streamlined installations in switch enclosures and other equipment. The current limiting design not only enhances protection against short circuit currents but also minimizes potential damage to sensitive equipment such as variable speed drives and rectifiers. Offering fast-acting overload protection, the JLLS080 provides reliable interruption of all overcurrents up to 200,000 amperes, ensuring that electric services and meters remain safeguarded under various conditions. With its capability to serve as both input and output fuses for surge-sensitive components, this product allows for the use of less costly equipment while maintaining high-performance standards.
