KLNR030 - 30Amp Fuse

KLNR030 - 30Amp Fuse

The KLNR030 is a 30A Class RK1 fast-acting, current-limiting fuse designed for your electrical equipment where quick response to overloads and short circuits is a key part of the protection strategy. Its current-limiting design also helps reduce equipment damage associated with the heating and magnetic effects of short-circuit currents. One detail matters most when choosing a replacement: this is a fast-acting fuse, so do not treat it as interchangeable with a time-delay fuse just because the amperage and voltage appear similar.

Key Features and Benefits

• 30A continuous current rating for equipment designed around a 30-amp Class RK1 fuse.
• Fast-acting (F) opening characteristic provides rapid overload and short-circuit protection.
• The Class RK1 fuse design gives buyers a clearly defined fuse class to match equipment requirements.
• Uses the KLNR Series' single-element silver-link design.
• Current-limiting construction helps reduce damage caused by the heating and magnetic effects of short-circuit currents.
• Handles applications up to 250VAC and 125VDC, subject to the equipment's specific electrical requirements.
• Manufacturer guidance identifies variable speed drives, rectifiers, and other surge-sensitive equipment as suitable examples for this fuse family's fast-acting characteristics.
• Industrial cartridge construction supports installation in an appropriate fuse block, clip, or holder.
• The non-indicating design keeps the configuration straightforward when built-in fuse-status indication is not required.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLNR030 as a Class RK1 current-limiting fuse and specifies a single-element silver-link design. The manufacturer documentation also discusses the KLNR/KLSR family in the context of applications requiring the current-limiting ability of UL Class RK1 fuses. However, the supplied specifications do not provide an individual UL listing or certification number specifically for KLNR030, so one should not be inferred from the information provided.

Where It Works Best

The KLNR030 30A fuse best matches electrical equipment that requires a 30A, Class RK1, fast-acting current-limiting fuse with matching voltage and interrupting requirements. The manufacturer's application guidance specifically calls out variable speed drives, rectifiers, and other equipment containing surge-sensitive components, where fast-acting protection can be particularly relevant.
