JLLN200 - 200Amp Fuse

JLLN200 - 200Amp Fuse

The Littelfuse JLLN200 is a 200-amp Class T fuse with tightly defined electrical and physical characteristics, making it easier to match to your equipment requirements. Rated for a maximum of 300VAC and 125VDC, the JLLN200 combines fast-acting operation with a current-limiting design and knife-blade construction. For equipment specifically calling for this combination of Class T configuration, 200A capacity, voltage ratings, and knife-blade format, the JLLN200 is a straightforward component built to last when properly selected and operated within its stated ratings.

Key Features and Benefits

• 200A continuous current rating: Clearly identifies the JLLN200 for equipment requiring a 200-amp fuse.
• Class T configuration: Provides a specific fuse classification that can be checked against equipment documentation and existing fuse requirements.
• Fast-acting opening: Littelfuse specifies a Fast-Acting (F) opening characteristic.
• Current-limiting design: Adds another important electrical characteristic to the compatibility checklist.
• 300VAC maximum voltage: Rated for AC applications within the manufacturer's specified 300VAC maximum.
• 125VDC maximum voltage: Also carries a separately specified 125VDC maximum rating.
• Knife-blade construction: Gives you a defined physical format to verify when matching the fuse to compatible equipment.
• Non-indicating design: The manufacturer's specifications identify the JLLN200 as a non-indicating fuse.

Material Compliance and Certifications

The manufacturer data supplied for the Littelfuse JLLN200 did not include specific UL, CSA, CE, RoHS, REACH, or other certification or material-compliance information. This should not be interpreted as meaning the product lacks a particular approval or compliance designation. Where a project, facility, or equipment specification requires a particular certification, confirm the requirement against current authoritative manufacturer documentation and the markings on the fuse itself.

Where It Works Best

The Littelfuse JLLN200 200A Class T fuse is best suited to compatible electrical equipment that specifically requires its combination of 200A continuous current rating, fast-acting opening characteristic, current-limiting design, and knife-blade construction. Its electrical ratings make the distinction equally clear: 300VAC maximum with a 200 kA interrupting rating at 300VAC, plus 125VDC maximum with a 20 kA interrupting rating at 125VDC. The specified fuse block, clip, or holder mounting method should also agree with the intended equipment.
