FAQs
LENRK500I is designed for 250 Vac and 125 Vdc systems with a 500 A current rating and a 200 kAIC interrupt capability. Its compact form (10.38 in long, 2.88 in high and wide) and standard packaging enable straightforward mounting in common control panels, with electrically isolated end caps for safer wiring and reduced risk during maintenance.
LENRK500I provides high-inrush motor protection through a 200 kAIC interrupt rating, permitting rapid, clean fault clearance without nuisance nuisance trips during startup. This supports motor longevity and uptime in applications such as conveyors and pumps, where short surges are typical yet faults must be reliably interrupted.
Yes. LENRK500I is UL Listed and CSA Certified, offering recognized safety assurances for industrial applications. This dual certification simplifies procurement, compliance reporting, and integration into systems that must meet strict regulatory requirements in North American facilities.
The non-indicating design reduces visual indicators inside panel doors, simplifying status reviews and reducing noise in crowded control rooms. It also lowers panel maintenance visibility concerns and pairs well with centralized monitoring strategies, while still delivering reliable protection and straightforward replacement when required.
