Eaton LPS-RK-450SP Fuse - Class RK1
Part Number: LPS-RK-450SP
Quick Summary
Eaton LPS-RK-450SP fuse is a Class RK1 time-delay device used for overcurrent protection in industrial control panels and motor circuits. When fuses trip unexpectedly, downtime, maintenance costs, and production delays rise, impacting overall plant reliability. This CE Marked and RoHS-compliant solution supports global installations while delivering predictable protection for critical loads. With a 450 A rating and high interrupt capability, it safeguards feeders and drives while fitting standard blade-end hardware. The design emphasizes reliability and installation ease, aligning with industry best practices for risk reduction and long-term operating efficiency. By pairing robust protection with common Bussmann catalog compatibility, it supports maintenance programs and asset availability in manufacturing, process automation, and HVAC environments.

Bussmann series Fuseology
Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, 70-600 A data sheet no. 1002
Time-delay, dual-element design provides selective interruption of overloads while limiting peak current, reducing arc energy and extending fuse life. This translates to lower maintenance costs and fewer unplanned outages in motor circuits and power feeders. In real-world installations, the dual-element approach helps avoid nuisance trips during inrush events, improving uptime for conveyors, pumps, and fans. The 450 A amperage rating and 600 Vac voltage rating cover a wide range of industrial loads, enabling one device to protect multiple feeders with consistent performance. Interruption ratings of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc ensure reliable operation in high-energy environments, supporting system selectivity and faster restoration after faults. Blade end x blade end connections and an electrically isolated end cap simplify installation and replaceability, reducing commissioning time and risk. The non-indicating fuse design minimizes external indicators, streamlining panel layouts and inventory management with standard packaging. These features collectively deliver measurable gains in reliability, safety, and total cost of ownership across industries that demand disciplined protection strategies.

FAQs
This fuse uses blade end x blade end connections and a standard packaging format, enabling straightforward drop-in replacement in Eaton Bussmann RK1 installations. Its electrically isolated end caps reduce risk during field servicing, allowing safer updates in motor control centers and switchgear without rewiring.
It is a time-delay, dual-element, current-limiting fuse rated for 450 A with 600 Vac and 300 kAIC interrupt rating at 600 Vac (100 kAIC at 300 Vdc). This combination supports motor starting inrush, short-circuit events, and protects upstream feeders while maintaining feed-through protection in MCCs.
Yes, the LPS-RK-450SP is CE Marked, ensuring compliance with European safety standards. It is RoHS compliant as part of Eaton’s global compliance program, enabling use in diverse international facilities and reducing regulatory risk during expansion.
Ideal for industrial panels, motor starters, MCCs, and power feeders where reliable overcurrent protection is required. The dual-element time-delay design is well-suited for loads with inrush currents and transient faults, while the high interrupt ratings support protection in high-energy circuits.
The fuse’s high interrupt capability and reduced nuisance trips translate to increased uptime and fewer unplanned outages. Its standard form factor and compatibility with Bussmann catalogs simplify stocking and replacements, lowering maintenance time and inventory costs in manufacturing, process automation, and HVAC environments.
