Littelfuse JLS035 Class J Fuse 35A 600VAC 200000 AIR Fast-Acting Industrial Cartridge

The JLS035 from Littelfuse is a top-tier solution designed for fast-acting protection of sensitive equipment such as variable speed drives and rectifiers. With its innovative current-limiting design, this fuse not only mitigates the risk of damage caused by short-circuit currents but also supports the use of more economical equipment by reducing the magnetic and heating effects typically associated with these situations. With an impressive interrupting rating of 200,000 A.I.R. at 600VAC, the JLS series ensures reliable interruption of overcurrents, effectively simplifying the demand for short-circuit calculations in general-purpose circuits. This fuse is particularly advantageous for resistive loads, including resistance electric heating and any systems requiring rapid overload protection, like those incorporating solid-state devices. While it offers characteristics similar to the KLNR/KLSR fast-acting Class RK1 fuses, its compact design allows for easy integration into equipment setups, enabling manufacturers to standardize on the 600-volt JLS fuses across various AC voltage ratings, thereby optimizing inventory management.
