JLLN080 - 80Amp Fuse

JLLN080 - 80Amp Fuse

The Littelfuse JLLN080 provides the specific rating your equipment requires for an 80-amp Class T fuse. Rated for a maximum of 300VAC or 125VDC, this fast-acting, current-limiting fuse has an AC interrupting capacity of 200 kA at 300VAC and a separate DC interrupting capacity of 20 kA at 125VDC. For maintenance, repair, or replacement work where the equipment documentation calls for these characteristics, the JLLN080 offers clear specifications that make comparison easier. When correctly selected, installed, and operated within its stated ratings, it's an electrical component built to last.

Key Features and Benefits

• 80A continuous current rating — Provides a clearly defined amperage for applications specifically requiring an 80-amp fuse.
• Fast-acting (F) opening characteristic — Littelfuse specifies the JLLN080 as fast-acting, an important detail when matching the fuse to equipment requirements.
• Current-limiting design — Part of the JLLN current-limiting fuse family.
• Class T fuse — Gives maintenance professionals another essential specification to verify rather than relying on amperage or appearance alone.
• 300VAC maximum voltage — Rated for compatible AC applications up to the specified 300VAC limit.
• 125VDC maximum voltage — The JLLN080 also carries a separately specified DC voltage rating.
• Knife-blade-style construction — The manufacturer identifies the JLLN080 as knife-blade construction with a Knife-Blade/Bolt-In configuration.
• Non-indicating — Designed without an indicating feature.

Material Compliance and Certifications

The manufacturer specifications provided for the JLLN080 did not include specific UL, CSA, CE, RoHS, REACH, or other certification or material-compliance information. That does not mean the product lacks those certifications or compliance attributes. If a particular listing or material requirement matters to the application, confirm it with authoritative documentation and markings for the exact Littelfuse JLLN080.

Where It Works Best

The Littelfuse JLLN080 80A Class T fuse is best suited to compatible electrical equipment that requires its combination of 80A continuous current, Class T configuration, fast-acting operation, current-limiting design, and knife-blade/bolt-in construction. For an AC application, the relevant limits are 300VAC maximum with a 200 kA interrupting rating at 300VAC. For DC service, check against the separate 125VDC maximum and 20 kA interrupting rating at 125VDC.
