Eaton LPS-RK-200SPI fuse - 600 Vac, 300 kAIC
Part Number: LPS-RK-200SPI
Quick Summary
Eaton LPS-RK-200SPI fuse protects critical electrical loads in industrial panels and motor drives. In busy facilities, nuisance trips and slow surge response can drive maintenance costs and uptime risk. This CE Marked, Bussmann Series RK1 time-delay fuse uses dual elements to deliver current-limiting protection at 600 Vac with a 300 kAIC interrupt rating, improving selectivity and safety. The 200 A rating and blade-end connection support scalable protection for MCCs, switchgear, and distribution panels. By combining robust protection with easy installation and clear compliance, it helps engineers minimize downtime and total cost of ownership in demanding environments.

FAQs
Install the LPS-RK-200SPI using blade-end x blade-end connections within compatible enclosures. Ensure the circuit is de-energized and verify 600 Vac rating and 200 A current path. Use the electrically isolated end caps for safe handling during installation and replacement, and confirm the fuse indicator option if monitoring is required.
The fuse provides 300 kAIC interrupt rating at 600 Vac, with a secondary rating of 100 kAIC at 300 Vdc. It is a 200 A, time-delay, current-limiting device designed for high-energy industrial circuits and motor protection in control panels.
Yes. The dual-element, time-delay design tolerates inrush and short surges common in motors, while delivering current-limiting protection to prevent damage to feeders and drives. With a 200 A rating and RK1 class construction, it suits MCCs, switchgear, and motor control centers in harsh industrial environments.
The product is CE Marked, confirming compliance with European safety standards. It adheres to Bussmann RK1 series design principles and uses standard RK1 protection, facilitating compliance within Europe and aligned industrial projects.
The fuse supports an indicator variant for status monitoring, enabling quick verification of fuse health in panels. Combined with easy blade-end installation and a compact form factor, this reduces maintenance time, minimizes downtime, and improves lifecycle planning for protection schemes.
