KLNR002 - 2Amp Fuse

KLNR002 - 2Amp Fuse

The KLNR002 is a 2A Class RK1 fast-acting, current-limiting fuse for your electrical equipment that requires a quick response to overload and short-circuit conditions. Its single-element, silver-link design provides the fast-acting characteristics of the KLNR Series. In contrast, the current-limiting design helps reduce equipment damage associated with the heating and magnetic effects of short-circuit currents. The fuse uses an industrial cartridge format, is non-indicating, and mounts in a compatible fuse block, clip, or holder. Because KLNR002 is fast-acting rather than time-delay, inrush current matters: the manufacturer cautions that KLNR/KLSR fuses used with inductive loads such as motors, solenoids, and transformers may require significant oversizing to avoid opening during harmless inrush.

Key Features and Benefits

• 2A continuous current rating for circuits and equipment specifically designed around a 2-amp Class RK1 fuse.
• The fast-acting (F) opening characteristic provides a quick response to overload and short-circuit conditions.
• Current-limiting construction helps reduce damage caused by the heating and magnetic effects associated with short-circuit currents.
• Uses the manufacturer's single-element, silver-link design for fast-acting protection.
• Well suited to certain surge-sensitive equipment, with variable speed drives and rectifiers specifically identified by the manufacturer.
• The Class RK1 configuration provides buyers with an essential compatibility specification when replacing an existing fuse.
• Industrial cartridge construction for equipment designed around the corresponding fuse format.
• Non-indicating design for installations where a built-in visual fuse-status indicator is not required.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLNR002 as a Class RK1 current-limiting fuse. It documents its 2A continuous rating, AC and DC voltage limits, interrupting ratings, fast-acting opening characteristic, industrial cartridge format, and mounting method.

Where It Works Best

The KLNR002 2A fuse is a strong match for equipment specifically designed for a 2A, Class RK1, fast-acting, current-limiting fuse. Manufacturer guidance cites variable speed drives, rectifiers, and other equipment with surge-sensitive components as examples where the fast-acting characteristics of the KLNR/KLSR Series can be useful. The manufacturer also notes that these fuses may be used as input or output fuses around surge-sensitive components.
