Special features
Non-indicating, High in-rush current motor protection
Feature → Business Impact → Application. Non-indicating design reduces visual clutter in control panels while still delivering dependable protection; maintenance requires planned checks rather than on-panel indicators, improving workflow efficiency in retrofit projects. High inrush current motor protection with a 200 kAIC interrupt rating minimizes nuisance trips and protects wiring and drives during startup transients, increasing line uptime in packaging and material handling lines. Class RK1 construction paired with 12 A at 600 V provides reliable selectivity for typical industrial motors, pumps, and conveyors, enabling safer cascaded protection and simpler coordination with upstream breakers. UL Listed and CSA Certified qualifications validate compliance with electrical safety standards, reducing approver time in procurement and audits. The 5 inch length and standard packaging support straightforward installation in Edison fuse holders, enabling quick substitutions during panel modernization without extensive rewiring. Industry context shows that non-indicating fuses paired with organized maintenance programs can lower total cost of ownership while preserving critical machine availability.

FAQs
The LESRK12 is designed for motor protection in industrial drive systems, including pumps, conveyors, and fans. It supports 12 A circuits at 600 V and offers high inrush tolerance with a 200 kAIC interrupt rating, making it well-suited for control panels and machine starters where reliable protection and minimal nuisance trips are essential.
LESRK12 provides 12 A amperage rating, 600 V voltage rating, and a 200 kAIC interrupt capacity. It is UL Listed and CSA Certified, with Class RK1 construction, ensuring compliance with common safety and performance requirements for industrial motor protection.
Yes. The LESRK12 is designed for standard 600 V motor circuits and integrates with Edison fuse holders. Its non-indicating, standard-length form factor simplifies installation and field retrofits, allowing consistent panel upgrades without extensive rewiring.
Installation is straightforward in standard Edison fuse blocks rated for 600 V. Because the fuse is non-indicating, maintenance planning should rely on preventive checks and coordination with motor starters or status-monitoring schemes. The fuse’s high interrupt rating supports robust protection while reducing the risk of downstream damage from faults.
