KLSR200 - 200Amp Fuse

KLSR200 - 200Amp Fuse

A 200A rating may be the first thing you notice on the KLSR200, but a correct fuse match goes well beyond amperage. The KLSR200 is a Class RK1 fast-acting, current-limiting fuse built around a single-element silver-link design for overload and short-circuit protection. When replacing a fuse, verify the 200A rating, Class RK1 designation, fast-acting characteristic, voltage and interrupting ratings, and physical configuration against the equipment requirements rather than matching on amperage alone.

Key Features and Benefits

• 200A continuous current rating for equipment specifically designed around a 200-amp fuse requirement.
• Class RK1 fuse classification helps establish the electrical and physical requirements to check when selecting a replacement.
• Fast-acting (F) operation provides fast overload and short-circuit protection.
• Uses the KLSR Series' single-element silver-link design.
• Current-limiting construction reduces equipment damage caused by the heating and magnetic effects of short-circuit currents.
• Maximum voltage rating of 600VAC.
• Also rated for DC service up to 300VDC, when properly applied.
• Knife-blade construction provides the specified connection format for this 200A model.
• The non-indicating design means the fuse does not include a blown-fuse indicator.
• Mounting is specified as a 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 does not provide a complete, product-specific material breakdown for the KLSR200, so do not assume materials for the fuse body, terminals, filler, and other components based on the silver-link description.

Where It Works Best

The KLSR200 200A fuse is best suited to electrical equipment specifically requiring a Class RK1, fast-acting, current-limiting fuse with the KLSR200's electrical and physical characteristics. The manufacturer specifically identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as examples where fast-acting KLNR/KLSR fuses can be used. Its current-limiting design is intended to reduce damage associated with the heating and magnetic effects of short-circuit currents.
