KLNR100 - 100Amp Fuse

KLNR100 - 100Amp Fuse

When your equipment calls for a 100A Class RK1 fast-acting fuse, the KLNR100 delivers a specific set of electrical and physical characteristics. The KLNR100 is a 100-amp current-limiting fuse rated for up to 250VAC and 125VDC, with a 200,000A interrupting rating at 250VAC and a 20,000A interrupting rating at 125VDC. For replacement work, don't rely on the 100A rating alone: confirm the Class RK1 designation, fast-acting characteristic, voltage and interrupting ratings, knife-blade format, and mounting requirements against the equipment specifications.

Key Features and Benefits

• 100A continuous current rating for equipment specifically designed around a 100-amp Class RK1 fuse.
• Fast-acting (F) operation provides fast overload and short-circuit protection.
• Class RK1 fuse with a current-limiting design.
• The KLNR/KLSR family uses a single-element silver link as part of its fast-acting design.
• Rated for a maximum of 250VAC and 125VDC.
• Current-limiting operation helps reduce equipment damage caused by the heating and magnetic effects of short-circuit currents.
• Knife-blade construction provides the physical format specified for KLNR100.
• Designed for installation using a compatible fuse block, clip, or holder.
• Non-indicating design—no built-in indicating feature.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLNR100 as a Class RK1 current-limiting fuse and describes the KLNR/KLSR family as having a single-element silver-link design. The manufacturer's information also covers applications that require the current-limiting ability of UL Class RK1 fuses.

Where It Works Best

The KLNR100 100A fuse is best for equipment that specifically requires a 100A, Class RK1, fast-acting, current-limiting fuse with the corresponding voltage, interrupting, mounting, and knife-blade requirements. The manufacturer specifically identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as examples where the fast-acting characteristics of the KLNR/KLSR family can be useful.
