KLSR002 - 2Amp Fuse

KLSR002 - 2Amp Fuse

When your equipment calls for a 2A Class RK1 fast-acting fuse, matching the amperage is only part of the job. The KLSR002 is a current-limiting industrial cartridge fuse rated for 600VAC maximum and 250VDC maximum, with fast-acting operation intended to respond quickly to overload and short-circuit conditions. For replacement work, verify the fuse class, voltage, interrupting capacity, opening characteristic, cartridge format, and mounting requirements—not simply the 2-amp rating.

Key Features and Benefits

• 2A continuous current rating for 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.
• The current-limiting design helps reduce equipment damage from the heating and magnetic effects associated with short-circuit current.
• Rated for operation up to 600VAC.
• Supports DC applications up to 250VDC, subject to the equipment's specifications.
• The KLSR series uses a single-element silver-link design to provide fast-acting performance.
• Industrial cartridge construction provides the specified physical format for compatible fuse installations.
• Designed for installation using a fuse block, clip, or holder.
• Confirm the non-indicating configuration when matching an existing fuse.

Material Compliance and Certifications

The supplied manufacturer information specifically identifies the KLSR series as using a single-element silver-link design. The supplied KLSR002 specifications do not include additional product-specific material details—such as the complete body, terminal, filler, or other material composition—so those details should not be assumed.

Where It Works Best

The KLSR002 suits electrical equipment that requires a 2A Class RK1 fast-acting, current-limiting industrial cartridge fuse with the corresponding voltage, interrupting, and physical requirements. The manufacturer's application guidance highlights variable speed drives, rectifiers, and other equipment with surge-sensitive components as examples where the KLSR series' fast-acting characteristics can be useful.

For AC equipment, verify compatibility with the 600VAC maximum rating and 200,000A interrupting rating at 600VAC. For DC applications, check against the 250VDC maximum and 20,000A interrupting rating at 250VDC. Physical compatibility also matters: KLSR002 is an industrial cartridge fuse intended for a fuse block, clip, or holder, with the LFR60030 Series as the specified holder reference.
