Littelfuse JLS020 Class J Fast-Acting 20A 600VAC 200000AIR Industrial Cartridge

The JLS020 from Littelfuse is a fast-acting fuse designed with a compact size for versatility in various applications. Its characteristics are comparable to the KLNR/KLSR fast-acting Class RK1 fuses, yet it offers an advanced current-limiting design capable of effectively interrupting short-circuit currents up to 200,000 amperes. This capability makes it ideal for protecting solid-state devices and equipment like variable speed drives and rectifiers, preventing damage from overheating and magnetic effects. Additionally, manufacturers can streamline their inventory by standardizing on 600-volt JLS fuses, ensuring reliable operation for a broad spectrum of general-purpose circuits with minimal motor load. The JLS020 provides crucial overload protection while simplifying equipment designs across different voltage ratings.
