KLNR025 - 25Amp Fuse

KLNR025 - 25Amp Fuse

When your equipment calls for a 25A Class RK1 fast-acting fuse, the details beyond amperage matter. The KLNR025 is a 25-amp current-limiting fuse with a single-element silver-link design engineered for fast-acting overload and short-circuit protection. The current-limiting design also helps reduce equipment damage associated with the heating and magnetic effects of short-circuit currents. Because this is a fast-acting fuse—not a time-delay fuse—extra care is needed around motors, transformers, solenoids, and other inductive loads that can produce normal inrush current.

Key Features and Benefits

• 25A continuous current rating for equipment specifically requiring a 25-amp fuse.
• Class RK1 configuration provides a defined fuse class for accurate replacement matching.
• Fast-acting (F) operation provides quick overload and short-circuit protection.
• A single-element silver-link design supports the KLNR Series' fast-acting characteristics.
• Current-limiting construction helps reduce equipment damage caused by the heating and magnetic effects associated with short-circuit currents.
• Rated for a maximum of 250VAC and 125VDC, giving the fuse clearly defined AC and DC operating limits.
• Manufacturer application guidance specifically includes variable speed drives, rectifiers, and other equipment containing surge-sensitive components.
• Industrial cartridge construction is intended for installation using a compatible fuse block, clip, or holder.
• The non-indicating design means this model does not provide built-in fuse-status indication.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLNR025 as a Class RK1 current-limiting fuse and describes its single-element silver-link design. The manufacturer also discusses this fuse family in connection with the current-limiting capability of UL Class RK1 fuses. However, the supplied information does not provide an individual certification or listing number for KLNR025, so you should not assume one.

Where It Works Best

The KLNR025 25A fuse suits electrical equipment designed for a 25A Class RK1 fast-acting, current-limiting fuse with matching voltage, interrupting, construction, and mounting requirements. Manufacturer guidance highlights variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications where the fast-acting characteristics of the KLNR/KLSR family can be useful.
