KLSR030 - 30Amp Fuse

KLSR030 - 30Amp Fuse

The KLSR030 is built for your applications that require a 30A Class RK1 fast-acting, current-limiting fuse. Rated for a maximum of 600VAC and 250VDC, it combines a single-element silver-link design with fast-acting operation to provide overload and short-circuit protection. The KLSR030 comes in a non-indicating industrial cartridge format and mounts in a compatible fuse block, clip, or holder; the LFR60030 Series is the corresponding holder series. For replacement work, don't stop at the 30A rating—confirm the fuse class, opening characteristic, voltage, interrupting capacity, physical configuration, and equipment requirements before matching.

Key Features and Benefits

• 30A continuous current rating for circuits designed around this specific fuse amperage.
• Class RK1 fuse configuration for applications requiring this defined fuse class.
• Fast-acting (F) operation provides quick response to overload and short-circuit conditions.
• Built around a single-element silver link, as specified for the KLSR Series.
• The current-limiting design helps reduce equipment damage from the heating and magnetic effects of short-circuit currents.
• Handles systems rated up to 600VAC.
• Also rated for up to 250VDC.
• Industrial cartridge construction gives the KLSR030 its specified physical format.
• Non-indicating design suits installations that do not require integral fuse-status indication.
• Installs using a compatible fuse block, clip, or holder.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLSR Series as using a single-element silver-link design and confirms the KLSR030's Class RK1, fast-acting, current-limiting configuration. The manufacturer provides no complete product-specific material composition beyond the silver-link information.

Where It Works Best

The KLSR030 30A fuse suits electrical equipment designed for a 30A Class RK1 fast-acting, current-limiting fuse with the corresponding voltage, interrupting, physical, and mounting requirements. The manufacturer specifically points to variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications where the fast-acting characteristics of the KLSR Series can be useful. Its current-limiting construction also helps reduce damage caused by the heating and magnetic effects of short-circuit currents.
