Special features
Non-indicating, High in-rush current motor protection
Non-indicating design keeps panels uncluttered, while the Class RK1 protection profile delivers reliable motor protection at the point of operation. This combination reduces troubleshooting time and provides consistent protection for all standard AC motors in small to mid-size drives. It’s ideal for motor starters, drives, and drive assemblies in conveyors, pumps, and packaging lines. High in-rush handling is enabled by a 200 kAIC interrupt rating, enabling reliable interruption of short circuits without nuisance trips. This improves uptime and reduces unplanned downtime in conveyors, pumps, and fans, where motor starts are frequent and load surges are common. 600 V voltage rating supports compatibility with common industrial power systems in North America and global installations, simplifying panel design and sourcing. Use in medium voltage motor drives and control circuits where safety margins and regulatory compliance are non-negotiable. UL Listed and CSA Certified endorsements reduce compliance risk and streamline specifications documentation for audits and supplier qualification. This makes it easier to specify LESRK2.5 in new builds and retrofit projects across manufacturing lines and process facilities. Standard packaging and a compact 5 in length with 0.81 in width and height fit typical Bussmann-style holders, enabling quick swaps and straightforward stocking. The 2.5 A rating with a 1.6 lb weight supports easy handling on the assembly line and in maintenance bays. Industry context: the Eaton Edison LESRK2.5 complements existing protection strategies, enabling safer, standardized, and maintainable electrical protection architectures across lines.
