LESRK50I - 50 Amp Fuse

LESRK50I - 50 Amp Fuse

The Eaton Edison LESRK50I fuse combines a 50A amperage rating, 600V voltage rating, and 200 kAIC interrupt rating in a compact 5.5-inch fuse body. For anyone matching a replacement fuse to your existing electrical equipment, those details matter—and so does getting the catalog number right. The LESRK50I measures 5.5 inches long by 1.06 inches high by 1.06 inches wide and weighs 2.6 lb. Eaton also highlights high in-rush current motor protection as a special feature, while UL Listed and CSA Certified status provides additional certification information for specification review.

Key Features and Benefits

• 50A current rating: Provides a precise specification point when matching a fuse to equipment requiring a 50-amp rating.
• 600V voltage rating: Clearly identifies the rated voltage for compatibility checks.
• High in-rush current motor protection: Eaton lists this as a special feature of the LESRK50I.
• UL Listed and CSA Certified: Both certifications are included in the manufacturer's specifications.

Material Compliance and Certifications

The Eaton Edison LESRK50I is specified as UL Listed and CSA Certified. The manufacturer lists its compliance designation as Not Applicable. No additional material-compliance designation was provided for this catalog number, so we did not infer one.

Where It Works Best

The LESRK50I 50A 600V fuse is a good fit for equipment or circuits that require a 50A rating, 600V rating, 200 kAIC interrupt rating, and high in-rush current motor-protection feature. When replacing an existing fuse, match the catalog number, amperage, voltage, interrupt rating, physical dimensions, and other equipment requirements rather than relying on appearance alone. Because Eaton's supplied information gives conflicting descriptions of the indicator feature, confirm that characteristic independently when indicator functionality matters to the application.
