KLSR012 - 12Amp Fuse

KLSR012 - 12Amp Fuse

The KLSR012 is a 12-amp Class RK1 fast-acting, current-limiting fuse designed for your electrical equipment that requires quick overload and short-circuit response. Its single-element silver-link design gives the KLSR Series its fast-acting characteristics. In contrast, the current-limiting design helps reduce equipment damage caused by the heating and magnetic effects of short-circuit currents. When matching a replacement, don't stop at the 12A marking—fuse class, voltage, interrupting capacity, opening characteristic, physical construction, and holder compatibility must all match the equipment requirements.

Key Features and Benefits

• 12A continuous current rating for equipment specifically designed around this amperage.
• Class RK1 fuse configuration provides the defined physical and electrical characteristics of this fuse class.
• Fast-acting (F) operation provides quick response to overload and short-circuit conditions.
• Built around a single-element silver-link design, a key characteristic of the KLSR Series.
• The current-limiting design helps reduce equipment damage from the heating and magnetic effects of short-circuit current.
• Handles applications requiring up to 600VAC maximum.
• Rated for up to 250VDC maximum where the equipment and circuit requirements match.
• Industrial cartridge construction gives technicians an important physical characteristic to confirm when selecting a replacement.
• Non-indicating configuration for applications that do not require integral fuse-status indication.
• Designed for installation using a compatible fuse block, clip, or holder.

Material Compliance and Certifications

The manufacturer specifically identifies the KLSR Series as using a single-element silver-link design. The supplied specifications for KLSR012 also confirm its Class RK1 classification, current-limiting family style, fast-acting opening characteristic, industrial cartridge construction, and stated AC and DC ratings.

Where It Works Best

The KLSR012 12A fuse suits electrical equipment that requires a 12A Class RK1 fast-acting, current-limiting industrial cartridge fuse with matching voltage and interrupting requirements. The manufacturer identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as examples where the fast-acting characteristics of the KLSR Series can be beneficial. Its current-limiting design also helps reduce damage caused by the heating and magnetic effects of short-circuit current.
