Eaton LPS-RK-200SP-TP Fuse - RK1 Class, Time-Delay
Part Number: LPS-RK-200SP-TP
Quick Summary
The Eaton LPS-RK-200SP-TP fuse is a time-delay, current-limiting blade-end device designed for electrical protection in industrial panels and motor drives. In modern automation environments, engineers often contend with nuisance trips and improper selectivity that disrupt uptime and increase service costs. Key standards include RoHS compliance and the RK1 class designation, with voltage ratings of 600 V and 300 Vdc and high fault-current interrupt performance. Its compact 9.63 in length and blade-end connections help streamline panel layouts, while the tin-plated construction supports durable, maintenance-friendly operation—reducing total cost of ownership.

Eaton Specification Sheet - LPS-RK-200SP-TP
Time-delay, current-limiting operation reduces nuisance inrush and supports selective coordination in distribution networks. This approach limits peak surge energy and minimizes unnecessary trip events, lowering maintenance costs and unplanned downtime. The LPS-RK-200SP-TP is well-suited for motor drives, machine control panels, and feeder blocks in manufacturing and process industries. High interrupt ratings—100 kAIC at 300 Vdc and 300 kAIC at 600 Vac—deliver robust fault protection. That capability helps safeguard feeders and switchgear against high fault currents, preserving downstream equipment. It fits in standard Bussmann RK1 assemblies and can be integrated into existing protection schemes without extensive rewiring. 200 A amperage rating balances protection and continuity for medium-size feeders and localized motor circuits. When paired with time-delay action, it prevents nuisance trips during startup while maintaining fast isolation during faults. This makes it suitable for industrial controls, HVAC, and packaging lines where reliability counts. Voltage ratings of 600 V and 300 Vdc allow compatibility across mixed AC and DC sources. That versatility simplifies panel design and reduces the need for multiple fuse types within the same enclosure. Installers appreciate consistent form factors and straightforward replacement within Eaton Bussmann's RK1 ecosystem. Tin-plated contacts and a standard, blade-end to blade-end connection streamline installation. RoHS compliance ensures environmental responsibility and regulatory alignment in modern facilities. With a compact 9.63 in length and standard packaging, it fits space-constrained panels and retrofit projects. Non-indicating fuse design keeps status simple, shifting monitoring responsibilities to the control system. Reliability and durability are enhanced by tin-plated metals and robust internal construction. The result is lower maintenance, predictable performance, and a lower total cost of ownership over the life of the installation.
