JLS100 - 100 Amp Fuse

JLS100 - 100 Amp Fuse

When the equipment calls for a 100A Class J fuse, matching the number on the label is only the beginning. The JLS100 is a fast-acting, current-limiting fuse rated for 100 amps and up to 600VAC, with a 200 kA interrupting rating at 600VAC. The JLS100 is also non-indicating, so when you're comparing it with an existing fuse, check the complete specification—not just the 100A rating. Fuse class, maximum voltage, opening characteristic, interrupting capacity, physical configuration, and mounting requirements all matter when determining whether you've found the right match.

Material Compliance and Certifications

The supplied product data identifies the JLS100 as a Class J, fast-acting, current-limiting fuse and provides its current rating, AC voltage rating, interrupting rating, knife-blade configuration, mounting method, and specified holder series.

Where It Works Best

The JLS100 suits electrical equipment that requires a 100A Class J fast-acting fuse with electrical and physical specifications matching this model. It's also a straightforward specification match when replacing an existing JLS100, assuming the equipment requirements remain the same.

For any other replacement comparison, look beyond amperage. Confirm that the equipment calls for a Class J, fast-acting fuse and operates within the JLS100's 600VAC maximum rating. Also check the circuit's required interrupting capacity against the fuse's 200 kA interrupting rating at 600VAC.
