Littelfuse JLS070 Class J Fuse Knife-Blade 70A 600V Fast-Acting

The JLS Series fuse from Littelfuse offers exceptional protection against damaging short-circuit currents, stopping them faster than traditional mechanical devices. Designed for applications requiring rapid overload protection, such as variable speed drives and other surge-sensitive equipment, this fast-acting fuse is also well-suited for general-purpose circuits with minimal motor loads. With a compact knife-blade package size, the JLS fuse features an impressive interrupting rating of 200,000 amperes at 600VAC, allowing for reliable interruption of overcurrents while minimizing potential damage to sensitive components. Its innovative current-limiting design enables manufacturers to streamline their inventory by standardizing on JLS fuses, making it an efficient choice for systems with dual voltage devices.
