JLLN110 - 110Amp Fuse

JLLN110 - 110Amp Fuse

The Littelfuse JLLN110 is easy to identify by its defining specifications. This 110A Class T fuse combines a fast-acting opening characteristic with a current-limiting design and knife-blade/bolt-in construction. The JLLN110 is non-indicating and is intended for mounting with a compatible fuse block, clip, or holder; Littelfuse specifies the LFT30200 Series as the PG holder. When your equipment calls for this exact combination of Class T configuration, amperage, voltage, interrupting capacity, and physical style, the JLLN110 is a straightforward component built to last when properly selected and used within its specified ratings.

Key Features and Benefits

• 110A continuous current rating: Provides a clearly defined amperage for equipment requiring a 110-amp fuse.
• Class T configuration: Makes fuse-class matching straightforward when checking existing equipment specifications.
• Fast-acting operation: Littelfuse designates the JLLN110 as Fast-Acting (F), an important characteristic to confirm when selecting a replacement.
• Current-limiting design: The JLLN110 belongs to Littelfuse's current-limiting fuse family.
• Dual AC/DC voltage specifications: Rated for a maximum of 300VAC and 125VDC, giving you exact voltage limits to compare with the intended application.
• Knife-blade/bolt-in construction: Provides a distinct physical configuration that can be checked against the equipment and mounting arrangement.
• Non-indicating fuse: Manufacturer data identifies the JLLN110 as a non-indicating model.

Material Compliance and Certifications

The manufacturer specifications supplied for the JLLN110 did not include specific UL, CSA, CE, RoHS, REACH, or other material-compliance or certification information. That doesn't mean the product lacks any particular certification; it simply means you shouldn't assume those details from the information provided. When a project, facility, or equipment specification requires a particular approval or compliance standard, verify the markings and authoritative documentation for the exact JLLN110 catalog number.

Where It Works Best

The Littelfuse JLLN110 110A Class T fuse suits compatible electrical equipment that requires its specific combination of 110A continuous current, fast-acting operation, current-limiting characteristics, 300VAC or 125VDC maximum voltage, and knife-blade/bolt-in construction. Its clearly stated AC and DC interrupting ratings also make it easier to check the fuse against the requirements documented for an existing application.
