FAQs
LESRK10 is a standard RK1 class fuse designed for Edison Bussmann-style holders and other RK1-compatible fuse blocks. It installs in 600 V motor protection circuits and fits typical panel enclosures that accept RK1 fuses. Use with a compatible fuse holder and appropriate conductor sizing to ensure reliable fault clearing and safe operation.
LESRK10 provides a 200 kAIC interrupt rating and a 600 V voltage rating, with a 10 A amperage rating. This combination supports robust short-circuit protection for high inrush motors while maintaining compatibility with common 600 V industrial power distributions.
A non-indicating RK1 fuse like LESRK10 reduces visual indicators and panel complexity, lowering component costs. It remains highly reliable for motor protection in places where status is monitored remotely or where indication is provided by an upstream diagnostic system, while preserving fast fault clearance and compliance with RK1 coordination standards.
LESRK10 is UL Listed and CSA Certified, confirming safety and regulatory compliance for electrical protection devices. These certifications support procurement in North American markets, facilitate approval of motor protection panels, and ensure adherence to recognized safety and performance standards for short-circuit protection.
LESRK10 is ideal for motor protection in 600 V systems such as AC drives, conveyors, and fans with high inrush motors. Using a properly rated RK1 fuse reduces motor damage and downtime, improves fault-clearance reliability, and simplifies maintenance with readily available replacement parts, delivering predictable return on investment in automation installations.
