FAQs
LESRK100I is designed for standard industrial motor protection roles and fits within common Edison fuse installations. It features electrically isolated end caps for safer wiring and reduced risk during maintenance. With a 7.88 in length and 1.11 in profile, it fits compact enclosures and integrates with typical 600 V motor circuits up to 100 A and 200 kAIC. Ensure enclosure space accommodates the non-indicating indicator and standard packaging quantity.
The LESRK100I is rated for 100 A, 600 V, with a 200 kAIC interrupt rating. These specs indicate the device can safely interrupt short-circuit faults up to 200 kA at 600 volts, while protecting motors and drives up to 100 A during inrush and startup events. This combination supports reliable motor protection in demanding industrial applications without nuisance trips.
Yes. The LESRK100I is designed for high inrush conditions typical of motors in conveyors and pumps. Its 200 kAIC interrupt rating and 600 V operating range help prevent nuisance trips during startup while providing robust protection against short circuits. For best results, select device size based on the motor full-load current and startup surge profile.
This fuse is UL Listed and CSA Certified, signaling compliance with key North American safety standards. These certifications simplify customer approvals, enable smoother OEM deployments, and support in-situ regulatory audits. When paired with 600 V operation and 200 kAIC interrupt rating, it aligns with industry norms for motor protection in industrial facilities.
LESRK100I contributes to ROI through reduced downtime from reliable inrush protection and a lower risk of motor damage during faults. With a non-indicating design and standard packaging, installation and stocking are straightforward, decreasing maintenance time and spare-part complexity.
