JLLS800 - 800 Amp Fuse

JLLS800 - 800 Amp Fuse

The JLLS800 is an 800-amp Class T fast-acting fuse designed for electrical equipment that requires a high-current, current-limiting fuse in a knife-blade/bolt-in configuration. If you're replacing an existing JLLS800, matching the catalog number is a sensible place to start, but don't stop there.

Material Compliance and Certifications

The supplied product data identifies the JLLS800 as a Class T, fast-acting, current-limiting fuse and provides its primary electrical ratings, mounting method, and physical configuration.

Where It Works Best

The JLLS800 is best suited to electrical equipment specifically designed to use an 800A fast-acting Class T fuse with this combination of electrical and mechanical specifications. For AC service, confirm that the application is within the fuse's 600VAC maximum rating and that its 200 kA AC interrupting capacity satisfies the equipment and circuit requirements.
