Littelfuse JLLN100 Class T Fuse 100A 300VAC 200000A Interrupting Knife-Blade Bolt-In Fast-Acting

Littelfuse’s JLLN Series fuses provide exceptional fast-acting overload protection for vital electrical equipment including variable speed drives and rectifiers. With a current limiting design that effectively mitigates damage from heating and magnetic effects associated with short-circuit currents, these fuses stand out for their ability to interrupt overcurrents up to an impressive 200,000 amperes. This protective solution is not only compact, requiring significantly less panel area than conventional Class R fuse blocks, but also offers enhanced reliability for surge-sensitive components by preventing the costly opening of semiconductor fuses. Ideal for a variety of applications, the JLLN Series ensures your systems remain safe and operational, with simplified installations due to the interchangeability with readily available equipment.
