JLS250 - 250 Amp Fuse

JLS250 - 250 Amp Fuse

When your equipment calls for a 250A Class J fuse, getting the amperage right is only part of the job. The JLS250 is a fast-acting, 250-amp fuse rated for use up to 600VAC, with a 200 kA interrupting rating at 600VAC. For anyone replacing an existing JLS250, the safest approach is to compare the full specifications rather than choosing by amperage alone.

Material Compliance and Certifications

The supplied product information identifies the JLS250 as a Class J, 250A fast-acting fuse in the JLS current-limiting family. It also specifies a 600VAC maximum voltage, a 200 kA interrupting rating, knife-blade construction, and the mounting arrangement.

Where It Works Best

The JLS250 suits electrical equipment that requires a 250A, fast-acting Class J fuse rated up to 600VAC. Its knife-blade configuration and fuse block/clip/holder mounting method should also match the equipment's physical requirements. The supplied product data identifies the LFJ60400 Series as the corresponding holder family.
