KLNR001 - 1Amp Fuse

KLNR001 - 1Amp Fuse

The KLNR001 is a 1A Class RK1 fast-acting, current-limiting fuse designed for circuits that require a quick response to overloads and short circuits. The manufacturer specifically identifies variable speed drives and rectifiers among the equipment that can benefit from this type of protection. For inductive loads with significant inrush current, the manufacturer cautions that KLNR fuses may need to be greatly oversized to avoid opening during harmless inrush, potentially limiting their role in those applications to short-circuit protection. That distinction matters when determining whether the KLNR001 is the correct fuse for your equipment.

Key Features and Benefits

• 1A continuous current rating for equipment specifically designed around a 1-amp Class RK1 fuse.
• The fast-acting opening characteristic provides a quick response for applications requiring fast overload and short-circuit protection.
• The current-limiting design helps reduce equipment damage from the heating and magnetic effects of short-circuit current.
• Class RK1 fuse configuration provides an important compatibility point when matching an existing fuse or equipment specification.
• The manufacturer describes the KLNR Series as using a single-element, silver-link design.
• Industrial cartridge construction fits equipment designed for the corresponding fuse format.
• Non-indicating design for applications that do not require a visual fuse-status indicator.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLNR/KLSR Series as Class RK1 current-limiting fuses and provides the KLNR001's electrical ratings, fast-acting opening characteristic, industrial cartridge construction, and mounting information.

Where It Works Best

The KLNR001 1A Class RK1 fuse best matches equipment that requires a 1A, fast-acting, current-limiting Class RK1 fuse in an industrial cartridge configuration. Manufacturer guidance specifically points to variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications where the fast-acting characteristics of the KLNR/KLSR Series can be useful.
