KLNR225 - 225Amp Fuse

KLNR225 - 225Amp Fuse

The KLNR225 is a 225A Class RK1 fast-acting, current-limiting fuse designed for your applications where quick response to overloads and short circuits is a key part of the protection scheme. Its single-element silver-link design provides fast-acting operation, while the current-limiting design helps reduce equipment damage caused by the heating and magnetic effects of short-circuit currents. It uses a non-indicating knife-blade configuration and is designed for installation in a compatible fuse block, clip, or holder; the supplied specifications identify the LFR25400 Series holder.

Key Features and Benefits

• 225A continuous current rating for electrical equipment specifically designed around a 225-amp fuse.
• The Class RK1 configuration provides a clearly defined fuse class for replacement and equipment-matching.
• Fast-acting (F) operation delivers fast overload and short-circuit protection.
• The KLNR series uses a single-element silver-link design.
• Current-limiting construction helps reduce damage associated with the heating and magnetic effects of short-circuit currents.
• Knife-blade construction provides the physical format specified for KLNR225.
• Non-indicating design means this catalog number does not include an indication feature.
• Installs using a compatible fuse block, clip, or holder.

Material Compliance and Certifications

The supplied manufacturer information identifies KLNR225 as a Class RK1 fuse. It confirms its fast-acting opening characteristic, current-limiting family style, single-element silver-link design, electrical ratings, and knife-blade construction.

Where It Works Best

The KLNR225 225A fuse is best suited to equipment specifically requiring a 225A Class RK1 fast-acting, current-limiting fuse with knife-blade construction. The manufacturer specifically points to variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications that can benefit from the KLNR/KLSR series' fast-acting characteristics.
