JLLS080 - 80Amp Fuse

JLLS080 - 80Amp Fuse

When you're replacing an 80-amp fuse, the label number is only one piece of the compatibility puzzle. The Littelfuse JLLS080 is a Class T, 80A fuse specified for fast-acting operation and current-limiting characteristics, with 600VAC and 300VDC maximum voltage ratings. For electricians, maintenance departments, and equipment owners looking specifically for a JLLS080 80A Class T fuse, those details provide practical checkpoints for confirming the right part. Properly matched to equipment requiring these specifications, this Littelfuse fuse is built to last while delivering the electrical characteristics defined for the JLLS080.

Key Features and Benefits

• 80A continuous current rating: Provides the specific amperage required by equipment designed around an 80-amp fuse.
• Class T configuration: The fuse class gives you a critical specification to verify when determining compatibility.
• Fast-acting operation: Littelfuse identifies the JLLS080 opening characteristic as Fast-Acting (F).
• Current-limiting family style: Provides the current-limiting characteristic specified for this JLLS Series model.
• 600VAC maximum rating: Suitable for compatible AC applications that fall within the manufacturer's stated electrical ratings.
• 300VDC maximum rating: Gives the JLLS080 a defined DC voltage specification as well.
• Knife-blade-style construction: Helps distinguish the JLLS080 physically when matching the fuse to compatible equipment.
• Non-indicating design: The manufacturer specifies "No" for the indicating characteristic.

Material Compliance and Certifications

The supplied manufacturer information does not specify UL, CSA, CE, RoHS, REACH, or other certification or material-compliance details for the JLLS080. This should not be interpreted to mean the fuse does or does not hold a particular certification. Where a project, facility, or equipment specification requires a particular approval or material standard, confirm the applicable product markings and current authoritative manufacturer documentation.

Where It Works Best

The Littelfuse JLLS080 80A Class T fuse is best for compatible equipment that calls for an 80-amp, fast-acting, current-limiting Class T fuse with knife-blade-style construction. It is a particularly clear match to investigate when the equipment requirements specify the JLLS080 catalog number, a 600VAC or 300VDC maximum voltage rating, the corresponding interrupting capacity, and a Knife-Blade/Bolt-In physical configuration. The specified LFT60100 Series PG holder is another useful compatibility point when evaluating the existing installation.
