LESRK3I - 3 Amp Fuse

LESRK3I - 3 Amp Fuse

The LESRK3I is a 3-amp, 600V AC Class R fuse built around a time-delay, current-limiting design. It has an indicating configuration, a 200 kA interrupting rating at 600V AC. If you're replacing an existing fuse, those details matter just as much as the 3A rating. Check the fuse class, voltage, interrupting rating, time-delay characteristic, indicator configuration, and physical size against the requirements of your equipment. The LESRK3I gives you a clearly defined set of specifications, making it easier to determine whether you're looking at the correct fuse rather than relying on amperage alone.

Material Compliance and Certifications

No material-compliance information or certification listings were provided in the supplied specifications for the LESRK3I. Rather than assume a certification that may not apply to this exact part number, any required compliance or certification status should be confirmed from authoritative product documentation.

Where It Works Best

The LESRK3I is for equipment or circuits requiring a 3A, 600V AC Class R fuse with a time-delay, current-limiting design, indicating configuration, and 200 kA interrupting rating.

For a replacement, compare more than the amperage printed on the fuse. Make sure the Class R designation, 600V AC rating, time-delay characteristic, interrupting rating, cartridge style, indicating configuration, and 5.0 x 0.81 x 0.81-inch physical size all match the equipment requirements. That extra check can make the difference between finding a fuse with the same amp rating and finding the correctly specified LESRK3I fuse for the application.
