KLSR001 - 1 Amp Fuse

KLSR001 - 1 Amp Fuse

The KLSR001 is a 1-amp Class RK1 fast-acting current-limiting fuse designed for your electrical equipment that requires a quick response to overloads and short circuits. Rated for up to 600VAC and 250VDC, it uses the KLSR series' single-element silver-link design. It comes in an industrial cartridge format for installation in a compatible fuse block, clip, or holder. One detail matters when selecting this fuse: fast-acting KLSR fuses can open on harmless inrush currents from inductive loads such as motors, solenoids, and transformers, so they should not be substituted for a time-delay fuse simply because the amperage and voltage appear to match.

Key Features and Benefits

• 1A continuous current rating for equipment specifically designed around a 1-amp Class RK1 fuse.
• Fast-acting operation provides quick response to overload and short-circuit conditions.
• The current-limiting design helps reduce equipment damage from the heating and magnetic effects of short-circuit currents, according to the manufacturer.
• Rated for a maximum of 600VAC, making the AC voltage rating an important part of replacement matching.
• Also rated for up to 250VDC.
• Single-element silver-link construction is a defining feature of the KLSR series.
• Industrial cartridge construction provides the specified physical format for compatible installations.
• Designed for mounting on a fuse block, clip, or holder.
• The supplied holder reference is the LFR60030 Series.
• Confirm the non-indicating design when matching an existing fuse.

Material Compliance and Certifications

The supplied manufacturer information identifies a silver link as part of the KLSR series' single-element construction. However, the manufacturer does not provide a complete product-specific material composition, so do not assume additional body, terminal, filler, or other material details for the KLSR001.

Where It Works Best

The KLSR001 best matches equipment that requires a 1A, Class RK1, fast-acting, current-limiting industrial cartridge fuse with the corresponding electrical and physical specifications. The manufacturer's application guidance specifically points to variable speed drives, rectifiers, and other equipment containing surge-sensitive components as examples where the KLSR series' fast response can be useful.

For AC service, confirm the equipment requirements against the 600VAC maximum and 200,000A at 600VAC interrupting rating. For DC service, verify compatibility with the 250VDC maximum and 20,000A interrupting rating at 250VDC. The fuse block, clip, or holder must also accommodate the specified cartridge format; the supplied holder reference is the LFR60030 Series.
