JLLS600 - 600Amp Fuse

JLLS600 - 600Amp Fuse

The JLLS600 is a 600-amp Class T fast-acting fuse for your electrical equipment that requires high interrupting capacity in a compact, current-limiting fuse configuration. With maximum ratings of 600VAC and 300VDC, the JLLS600 carries a 200 kA AC interrupting rating at 600VAC and a 20 kA DC interrupting rating at 300VDC. The fuse uses a knife-blade/bolt-in construction and is intended for installation in a compatible fuse block, clip, or holder; the specified holder family is the LFT60600 Series.

Material Compliance and Certifications

The supplied product information identifies the JLLS600 as a Class T, fast-acting, current-limiting fuse and provides its principal electrical ratings, construction style, interrupting capacities, and mounting method.

Where It Works Best

The JLLS600 600A Class T fuse is best suited to electrical equipment specifically engineered to use a 600-amp, fast-acting Class T fuse with the corresponding voltage and interrupting ratings. For AC equipment, the JLLS600 is rated for a maximum of 600VAC with a 200 kA interrupting rating at 600VAC. Its current-limiting classification and knife-blade/bolt-in construction should also match the intended equipment requirements.
