Littelfuse® JLS040 POWR-GARD® JLS High Speed Fast Acting Fuse, 40 A, 600 VAC, 200 kA Interrupt, Class J Series, Cartridge Body

JLS series fuses provide space-saving, Fast-Acting overload and short circuit protection for non-inductive loads. When used for motors or other inductive loads, the ampere rating of JLS series fuses must be increased to prevent nuisance opening on inrush currents. In such applications, JLS fuses may provide only short circuit protection.
