BUSS JLS200 Class J Fuse

JLS200 is a Littelfuse JLS Series Class J fast-acting fuse rated for 200 A at 600 V, designed for bolt-on mounting in industrial equipment and power-distribution panels. This 200 A Class J device features a bolt-on body and a non-indicating design, enabling secure installation in 600 V circuits. As a UL Class J fuse, it provides rapid overcurrent interruption with an interrupting rating up to 200 kA at 600 VAC in appropriate fault conditions, making it suitable for high-current protection in demanding applications. Typical uses include motor drives, switchgear, power-distribution panels, and control cabinets where a 200 A protection level at up to 600 V is required. Its fast-acting characteristic minimizes damage from short circuits and surges while remaining compatible with standard Class J fuse blocks and holders designed for 600 V systems. This fuse is part of the JLS family—Class J fuses intended for reliable protection in industrial equipment rated up to 600 V.
