KLSR100 - 100Amp Fuse

KLSR100 - 100Amp Fuse

When your equipment calls for a 100A Class RK1 fast-acting fuse, matching the amperage is only part of getting the replacement right. The KLSR100 is a 100-amp, fast-acting, current-limiting fuse featuring a single-element silver-link design, knife-blade construction, and ratings up to 600VAC and 300VDC. The KLSR100 is non-indicating and mounts in a compatible fuse block, clip, or holder; the specified PG holder is the LFR60100 Series. Before replacing an existing fuse, confirm the 100A rating, Class RK1 requirement, voltage, interrupting capacity, fast-acting characteristic, knife-blade configuration, and equipment specifications.

Key Features and Benefits

• 100A continuous current rating for electrical equipment specifically requiring a 100-amp fuse.
• Class RK1 design provides a clearly defined fuse class for replacement and application matching.
• Fast-acting (F) opening characteristic provides fast overload and short-circuit protection.
• Built with the KLSR Series' single-element silver-link design.
• Current-limiting construction helps reduce damage caused by the heating and magnetic effects associated with short-circuit currents.
• Rated for operation in compatible circuits up to 600VAC.
• Also rated up to 300VDC when used within the specified DC requirements.
• Knife-blade construction provides the specified physical connection style for this 100A model.
• The non-indicating design means it has no built-in blown-fuse indicator.
• Designed for installation using a compatible fuse block, clip, or holder.

Material Compliance and Certifications

The supplied manufacturer information identifies a single-element silver-link design for KLSR Series fuses. It does not provide a complete, product-specific material composition for the KLSR100, so do not assume additional body, terminal, filler, or other construction materials based on the information provided.

Where It Works Best

The KLSR100 100A fuse best matches equipment designed around a 100A Class RK1 fast-acting, current-limiting fuse with compatible voltage, interrupting, and physical requirements. Manufacturer guidance specifically identifies variable speed drives, rectifiers, and equipment containing surge-sensitive components as examples where the fast-acting characteristics of KLSR fuses can be useful. The current-limiting design also helps reduce equipment damage associated with the heating and magnetic effects of short-circuit currents.
