JLS200 - 200 Amp Fuse

JLS200 - 200 Amp Fuse

When you're replacing a 200A Class J fuse, matching the number on the amp rating isn't enough. The JLS200 is a fast-acting fuse rated for 200 amps and up to 600VAC, with a 200 kA interrupting rating at 600VAC. For someone trying to confirm a replacement, the important details are right here: 200A, Class J, 600VAC, fast-acting operation, 200 kA interrupting capacity, and knife-blade construction. Checking all of those specifications against the equipment requirements can help avoid choosing a fuse that matches in amperage but not in electrical or physical configuration.

Material Compliance and Certifications

The supplied product specifications identify the JLS200 as a Class J, fast-acting fuse and provide its current rating, AC voltage rating, interrupting rating, physical configuration, mounting method, and holder series.

Where It Works Best

The JLS200 is best suited to electrical equipment that specifically requires a 200A fast-acting Class J fuse with a maximum AC voltage rating of 600V and the corresponding knife-blade configuration. It's also a clear match to investigate when replacing an existing JLS200, and you need the electrical and physical specifications to line up.
