Eaton LPS-RK-17-1/2SPI Fuse - CE Marked RK1 Class

Time-delay dual-element design provides both rapid fault interruption and surge tolerance, enabling safer, more predictable electrical protection for motor drives, heavy machinery, and protective control panels in challenging industrial environments. This combination improves selectivity by allowing brief transients to pass without tripping, while still shutting down sustained faults that threaten equipment, causing unplanned outages and costly downtime. In industrial control panels, compact footprints and compatibility with RK1 class devices simplify retrofits, while CE compliance and 600 Vac capability support broad integration across OEM builds. Current-limiting capability confines fault current to downstream components during faults, preserving wiring insulation, protecting contactors, relays, and sensitive electronics from damaging surge energy. With a 300 kAIC interrupt rating at 600 Vac, upstream breakers and feeders stay within safe margins, enhancing personnel safety, minimizing arc flash exposure, and improving overall system reliability. That performance translates to fewer component failures, quicker fault isolation during maintenance, and more predictable mean time between failures across production lines. The 17.5 A amperage rating aligns with common protection schemes for small to mid-size industrial loads, enabling straightforward cross-reference with existing panels and engineering standards. 600 Vac and 300 Vdc voltage ratings cover primary and auxiliary circuits in most control systems, reducing the need for adapters or multiple fuse types during upgrades. These specifications simplify bills of materials, shorten engineering cycles in OEM projects, and support scalable protection as equipment capacity grows. Physical form factor supports fast, drop-in replacement in RK1 basings, holders, and standard enclosures, minimizing downtime during servicing and spare parts management. Five-inch length and 0.81 inch width and height match typical Bussmann RK1 footprints, allowing straightforward field replacements without custom enclosures. Packaging of ten per order streamlines stocking for maintenance teams, procurement workflows, and site-wide consistency across multiple machines. CE marking demonstrates regulatory alignment for European and global installations, while RK1 classification confirms proper coordination within cascaded protection schemes and standards. Comprehensive catalogs and data sheets, including the Low Voltage Branch Circuit Fuse chapters, support formal approvals, training, and engineering sign-offs. Availability of indicator options and variations, plus standard versus indicator variants, aids condition monitoring, remote fault reporting, and asset health programs.
