KLNR070 - 70Amp Fuse

KLNR070 - 70Amp Fuse

A 70-amp rating may be the first thing you notice, but choosing the right replacement fuse means matching more than amperage. The KLNR070 is a 70A Class RK1 fast-acting, current-limiting fuse built around a single-element silver-link design for fast 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.

Key Features and Benefits

• 70A continuous current rating for equipment designed around a 70-amp Class RK1 fuse.
• Class RK1 configuration provides an important compatibility characteristic when identifying a suitable replacement.
• Fast-acting (F) operation provides fast overload and short-circuit protection.
• Uses the KLNR/KLSR family's single-element silver-link design.
• Current-limiting construction helps reduce equipment damage caused by the heating and magnetic effects of short-circuit currents.
• Industrial cartridge construction is intended for installation using an appropriate fuse block, clip, or holder.
• Non-indicating design means the KLNR070 does not include an indicating feature.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLNR070 as a Class RK1 current-limiting fuse and states that the KLNR/KLSR family uses a single-element silver link. The manufacturer also discusses the series in the context of applications requiring the current-limiting ability of UL Class RK1 fuses.

Where It Works Best

The KLNR070 70A fuse is a strong fit for electrical equipment specifically designed to use a 70A Class RK1 fast-acting, current-limiting fuse with matching voltage, interrupting, physical, and mounting requirements. The manufacturer specifically identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications where the fast-acting characteristics of KLNR/KLSR fuses can be useful. Their current-limiting design also reduces damage from the heating and magnetic effects of short-circuit currents.
