High power protection is built into the LESRK500I with a 500 A amperage rating and a 200 kAIC interrupt rating, paired with a 600 V maximum voltage. This combination ensures fast, precise fault clearing for heavy-inductive loads, reducing arcing damage and downtime in motor circuits. In practice, manufacturers in conveyors, pumps, and fans benefit from fewer unexpected trips and safer, more reliable starts, even under demanding startup transients. Electrically isolated end caps simplify maintenance and replacement, enabling technicians to swap fuses safely without disturbing feed-through connections. The design also supports safer test and control wiring during commissioning and routine service, improving site safety and cutting maintenance time in challenging industrial environments. Measuring 13.38 in long and 2.88 in square cross-section with a 3.44 lb weight, the LESRK500I fits compact switchgear and motor-control panels where space is at a premium. Standard packaging and the Eaton Edison lineage help ensure straightforward installation, with existing Bussmann catalogs and the Edison full-line catalog supporting accurate part selection. Special features underscore its capability for high inrush protection and indicating readiness, enabling quick fault identification and targeted protective action. This helps plant engineers design safer motor circuits and streamline preventive maintenance by clearly spotting faults without lengthy diagnostic dances. Certified UL Listed and CSA Certified, the LESRK500I meets essential regulatory expectations for industrial control gear in 600 V systems. Review the Eaton specification sheet for detailed electrical ratings and installation guidelines, and leverage the included catalogs to validate compatibility with existing panels and control schemes.
