KLNR110 - 110Amp Fuse

KLNR110 - 110Amp Fuse

The KLNR110 is a 110A Class RK1 fast-acting current-limiting fuse designed for your applications where quick response to overloads and short circuits is a key part of the protection strategy. Rated for a maximum of 250VAC and 125VDC, it carries an AC interrupting rating of 200,000A at 250VAC and a DC interrupting rating of 20,000A at 125VDC, and it replaces an existing fuse. Don't stop after matching the 110A rating. The Class RK1 designation, fast-acting characteristic, voltage limits, interrupting rating, physical configuration, and mounting requirements should all match the equipment specifications.

Key Features and Benefits

• 110A continuous current rating for equipment requiring a 110-amp Class RK1 fuse.
• The fast-acting (F) opening characteristic provides a fast response to overload and short-circuit conditions.
• Current-limiting Class RK1 design helps control damaging short-circuit current.
• KLNR/KLSR fuses use a single-element silver-link design.
• Rated for up to 250VAC in AC applications.
• Also rated for up to 125VDC where the equipment and circuit requirements match.
• Knife-blade construction provides the specified physical format for KLNR110.
• Non-indicating configuration with no built-in indication feature.

Material Compliance and Certifications

The supplied manufacturer information identifies KLNR110 as a Class RK1 current-limiting fuse and specifies a single-element silver-link design for the KLNR/KLSR family. The manufacturer also discusses the current-limiting capability of UL Class RK1 fuses in its application guidance.

Where It Works Best

The KLNR110 110A fuse suits electrical equipment designed for a 110A Class RK1 fast-acting, current-limiting fuse with matching electrical and physical requirements. The manufacturer's application guidance specifically calls out variable speed drives, rectifiers, and other equipment containing surge-sensitive components as examples where KLNR/KLSR fast-acting protection may be appropriate.
