KLNR200 - 200Amp Fuse

KLNR200 - 200Amp Fuse

When your equipment calls for a 200A fast-acting Class RK1 fuse, the catalog number is only the first step in verifying the replacement. The KLNR200 combines a 200A continuous current rating with fast-acting operation and the current-limiting characteristics of the KLNR series. Before replacing a fuse based on amperage alone, confirm that the equipment also requires Class RK1, fast-acting operation, the applicable voltage and interrupting ratings, and the correct physical configuration.

Key Features and Benefits

• 200A continuous current rating for equipment specifically designed to use a 200-amp fuse.
• Class RK1 design provides a defined fuse class to match equipment requirements.
• Fast-acting (F) operation provides fast overload and short-circuit protection.
• KLNR series construction uses a single-element silver link.
• Current-limiting design helps reduce equipment damage caused by the heating and magnetic effects associated with short-circuit currents.
• Knife-blade construction provides the physical format specified for the KLNR200.
• Non-indicating configuration—this catalog number does not incorporate an indication feature.
• Designed for installation using a compatible fuse block, clip, or holder.

Material Compliance and Certifications

The supplied manufacturer information confirms that the KLNR200 is a Class RK1 fuse and identifies its fast-acting operation, current-limiting family style, single-element silver-link design, electrical ratings, and knife-blade construction. The manufacturer also discusses the series in the context of applications requiring the current-limiting capability of UL Class RK1 fuses.

Where It Works Best

The KLNR200 200A fuse is a strong match for electrical equipment specifically designed around a 200A Class RK1 fast-acting, current-limiting fuse with knife-blade construction. The manufacturer specifically identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as examples where the KLNR/KLSR series' fast-acting characteristics can be useful. For AC installations, confirm the equipment requirements against the 250VAC maximum and 200,000A interrupting rating at 250VAC. For DC service, verify compatibility with the 125VDC maximum and 20,000A interrupting rating at 125VDC.
