Littelfuse JLS100 Class J Fuse 100A 600V 200000A Interrupting Knife-Blade Fast-Acting

Littelfuse’s JLS100 from the JLS Series is engineered for superior performance in electrical applications, particularly where dual voltage devices are involved. This fuse simplifies the manufacturing process for equipment by allowing standardization on 600-volt JLS fuses and Class J fuse blocks across all AC voltage ratings, effectively reducing inventory needs. Its exceptional current-limiting design minimizes damage caused by short-circuit currents, providing reliable protection for sensitive equipment such as variable speed drives and rectifiers, which often feature surge-sensitive components. With a robust interrupting rating of 200,000 amps, this fast-acting fuse quickly halts damaging overcurrents, making it an ideal choice for general-purpose circuits, resistive loads, and tasks that demand rapid overload protection.
