Non-indicating, High in-rush current motor protection
High inrush tolerance combined with a 15 A rating and Class RK1 construction delivers reliable motor protection without compromising startup torque. The business impact is clear: fewer nuisance trips during start-up translate to reduced downtime and smoother line operation. This is especially valuable in conveyor systems, pumps, and machine tools where motors frequently cycle on and off. The 200 kAIC interrupt rating and 600 V operating voltage ensure safe fault current clearing, protecting conductors and downstream devices in demanding industrial drives such as packaging lines and processing equipment. The non-indicating design simplifies maintenance and diagnostics, reducing panel downtime and spare-parts management while delivering consistent protection. CSA Certified and UL Listed across markets support regulatory compliance, ease procurement, and enable use in multinational projects. Standard packaging and a compact footprint facilitate quick panel integration and straightforward field replacement, reducing installation time and labor costs. Overall, LESRK15 delivers predictable protection, improved uptime, and a lower total cost of ownership for OEMs and end users alike.

FAQs
LESRK15 is designed for motor protection in industrial control panels and motor starters where 15 A protection is required and where 600 V maximum operating voltage is suitable. Its Class RK1 construction supports standard motor protection schemes, and its non-indicating design simplifies replacement in existing bundles and panels. It pairs well with AC motors used on conveyors, pumps, fans, and machine tools, reducing nuisance trips during inrush while preserving start-up torque.
LESRK15 is engineered for high inrush tolerance typical of short-start duty motors. Its 15 A rating and Class RK1 characteristics allow the fuse to momentarily accommodate surge currents without tripping, protecting the motor windings and drive circuitry. This results in smoother motor starts, reduced electrical noise, and fewer process interruptions in packaging lines, pumps, and material-handling equipment.
Yes. The LESRK15 fuse is CSA Certified and UL Listed, reflecting compliance with North American safety standards. It is rated for 600 V and provides a 200 kAIC interrupt rating, which supports safe operation in industrial environments. These certifications help OEMs meet regulatory requirements, simplify procurement, and facilitate multi-site installations with consistent protection.
Install LESRK15 in standard fuse blocks used for motor protection in control panels. Its Class RK1, non-indicating design is compatible with common panel layouts and spare-parts inventories. With a compact footprint (5 in length, 0.81 in width and height) and 1.6 lb weight, it fits in crowded OEM enclosures and minimizes panel depth. Ensure conductor sizing and wiring torques follow supplier guidelines for reliable protection.
LESRK15 offers predictable protection with reduced nuisance trips, lowering unplanned downtime and maintenance visits for motor-driven lines. Its rugged 200 kAIC interrupt rating improves fault clearance reliability, reducing downstream damage and panel wear. Certifications streamline cross-border deployments, while its non-indicating design lowers diagnostic complexity, helping maintenance teams complete replacements faster and with fewer spare parts.
