KLSR015 - 15Amp Fuse

KLSR015 - 15Amp Fuse

When your equipment calls for a 15A Class RK1 fast-acting fuse, the KLSR015 delivers a specific set of electrical and physical characteristics. This current-limiting industrial cartridge fuse is rated for up to 600VAC and 250VDC, with an interrupting capacity of 200,000A at 600VAC and 20,000A at 250VDC. KLSR015 is non-indicating and is installed with a compatible fuse block, clip, or holder; the LFR60030 Series is the corresponding holder series. For replacement work, matching the 15A rating is only part of the job—confirm the fuse class, voltage, interrupting capacity, opening characteristic, cartridge format, and holder requirements against the equipment specifications.

Key Features and Benefits

• 15A continuous current rating for equipment requiring this specific amperage.
• Class RK1 design provides the defined electrical and physical characteristics associated with this fuse class.
• Fast-acting (F) opening characteristic provides quick overload and short-circuit response.
• Uses a single-element silver link, a defining construction feature stated for the KLSR Series.
• The current-limiting design helps reduce equipment damage from the heating and magnetic effects of short-circuit currents.
• Rated for electrical systems up to 600VAC.
• Also carries a 250VDC maximum voltage rating for compatible DC applications.
• Industrial cartridge construction gives technicians a clear physical format to verify during replacement.
• Non-indicating design for applications that do not require integral fuse-status indication.
• Mounts through a compatible fuse block, clip, or holder.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLSR Series as using a single-element silver-link design. For KLSR015 specifically, the provided specifications confirm its Class RK1 classification, fast-acting operation, current-limiting family style, industrial cartridge format, and AC/DC electrical ratings.

Where It Works Best

The KLSR015 best matches electrical equipment designed for a 15A Class RK1 fast-acting, current-limiting fuse with the corresponding 600VAC or 250VDC requirements. The manufacturer specifically points to variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications where the fast-acting characteristics of KLSR fuses can provide useful protection. Its current-limiting design also aims to reduce equipment damage from the heating and magnetic effects produced by short-circuit current.
