KLNR080 - 80Amp Fuse

KLNR080 - 80Amp Fuse

When you're replacing an 80A Class RK1 fuse, amperage is only part of the match. The KLNR080 is an 80A fast-acting, current-limiting fuse with a single-element silver-link design engineered for fast overload and short-circuit protection. Its current-limiting design also reduces equipment damage caused by the heating and magnetic effects of short-circuit currents. For replacement work, matching the 80A rating, Class RK1 configuration, fast-acting response, voltage ratings, interrupting ratings, and physical format gives you a much more reliable compatibility check than amperage alone.

Key Features and Benefits

• 80A continuous current rating for equipment specifically designed around an 80-amp Class RK1 fuse.
• Class RK1 fuse configuration provides a key compatibility point when matching an existing fuse or equipment requirement.
• Fast-acting (F) operation provides fast overload and short-circuit protection.
• Built around the KLNR/KLSR family's single-element silver-link design.
• 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 KLNR080.
• Designed for installation using a compatible fuse block, clip, or holder.
• Non-indicating design with no built-in indicating feature.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLNR080 as a Class RK1 current-limiting fuse and specifies a single-element silver-link design for the KLNR/KLSR family. The manufacturer also discusses the series in applications that require the current-limiting ability of UL Class RK1 fuses.

Where It Works Best

The KLNR080 80A fuse best matches electrical equipment that requires an 80A Class RK1 fast-acting, current-limiting fuse with the corresponding voltage, interrupting, and knife-blade requirements. The manufacturer specifically identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as examples where the series' fast-acting protection can be useful. Its current-limiting design is intended to reduce damage associated with the heating and magnetic effects produced by short-circuit currents.
