KLSR025 - 25Amp Fuse

KLSR025 - 25Amp Fuse

When your equipment calls for a 25A Class RK1 fast-acting fuse, matching the amperage is only the beginning. The KLSR025 is a fast-acting, current-limiting industrial cartridge fuse rated for 600VAC maximum and 250VDC maximum. The manufacturer specifically identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications for the KLSR family. This non-indicating fuse uses an industrial cartridge format and installs in a compatible fuse block, clip, or holder; the LFR60030 Series is the corresponding holder series.

Key Features and Benefits

• 25A continuous current rating for equipment requiring this specific fuse amperage.
• Class RK1 design provides a defined fuse class for accurate replacement matching.
• Fast-acting (F) opening characteristic delivers quick response to overloads and short circuits.
• Uses a single-element silver-link design.
• Current-limiting construction helps reduce damage caused by the heating and magnetic effects of short-circuit currents.
• Rated for a maximum of 600VAC.
• Suitable for systems requiring up to 250VDC, depending on the equipment's full electrical requirements.
• Industrial cartridge construction provides the specified physical format for compatible installations.
• Non-indicating design for applications that do not require integral fuse-status indication.
• Mounts using a compatible fuse block, clip, or holder.

Material Compliance and Certifications

The supplied manufacturer information specifically identifies a single-element silver-link design for the KLSR Series. It also confirms the KLSR025 as a Class RK1, fast-acting, current-limiting fuse with industrial cartridge construction.

Where It Works Best

The KLSR025 25A fuse is best suited to electrical equipment specifically designed for a 25A Class RK1 fast-acting, current-limiting fuse with the corresponding voltage and interrupting requirements. The manufacturer identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications where the KLSR Series' fast-acting characteristics can be useful. Its current-limiting design is intended to reduce equipment damage associated with the heating and magnetic effects produced by short-circuit currents.
