JLLN1100 - 1100Amp Fuse

JLLN1100 - 1100Amp Fuse

Choosing the right fuse for 1100 amps goes beyond just matching numbers and shapes. The Littelfuse JLLN1100 is a Class T, fast-acting, current-limiting fuse featuring a durable knife-blade/bolt-in design with clear AC and DC ratings. It's non-indicating and should be used with a compatible fuse block or holder, like the LSCR Series PG holder. If your equipment needs specific electrical ratings and a solid build, the JLLN1100 is a reliable choice when used within its designed limits.

Key Features and Benefits

• 1100A continuous current rating: Provides the specified current rating needed for applications calling for an 1100-amp Class T fuse.
• Fast-acting opening characteristic: Littelfuse identifies the JLLN1100 as Fast-Acting (F), giving you an important characteristic to match against the equipment requirements.
• Current-limiting design: Part of the Littelfuse current-limiting fuse family.
• Class T fuse: A clearly defined fuse classification that helps narrow the compatibility check beyond amperage alone.
• 300VAC maximum rating: Suitable where the equipment requirements call for this fuse and an AC voltage within its specified maximum.
• 125VDC maximum rating: Also carries a manufacturer-specified DC voltage rating of 125V maximum.
• Knife-blade/bolt-in construction: Gives you a specific physical configuration to verify against the fuse mounting arrangement.
• Non-indicating design: Manufacturer specifications identify the JLLN1100 as non-indicating.

Material Compliance and Certifications

The manufacturer specifications supplied for the JLLN1100 did not include specific UL, CSA, CE, RoHS, REACH, or other certification or material-compliance information. This should not be interpreted as meaning the fuse lacks a particular certification. If an installation, facility, or project requires specific approvals or material-compliance standards, verify them using authoritative documentation for the exact JLLN1100 catalog number.

Where It Works Best

The Littelfuse JLLN1100 Class T fuse is best for compatible electrical equipment that requires 1100A continuous current, fast-acting operation, current-limiting characteristics, 300VAC or 125VDC maximum voltage, and knife-blade/bolt-in construction. Its separate AC and DC interrupting ratings are especially important: 200 kA at 300VAC and 20 kA at 125VDC. The mounting arrangement must also agree with the equipment requirements.
