Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, up to 600 A data sheet no. 1001
Time-delay, dual-element design provides selective fault handling, absorbing short surges without nuisance trips and reducing unplanned downtime in motor circuits and conveyors. This translates to faster line restart times, improved equipment availability, and lower maintenance costs in automated production lines. The current-limiting feature reduces fault energy, protecting downstream devices and enabling smaller conductor sizing where appropriate, which lowers total installed cost in control panels and machine tools. The high interrupt rating of up to 300 kAIC at 600 Vac ensures safe interruption in panels feeding large loads, enhancing safety and reliability for main feeders and transformer-equipped systems. Ferrule-end connections simplify installation with common terminal hardware, while an optional indicator aids quick fault localization during maintenance. Electrically isolated end caps reduce shock risk during service, supporting safer, faster commissioning and testing in industrial settings. All of this aligns with RK1-class performance and CE compliance to meet modern automation standards.

FAQs
LPS-RK-60SPI uses ferrule-end terminations that are compatible with standard crimped ferrules and panel bus bars. When installing, verify ferrule diameter and crimp quality, tighten terminals to the manufacturer’s torque specifications, and ensure proper insulation to prevent arcing. This design simplifies replacement in crowded control panels and reduces service time during maintenance.
Key specs include a 60 A amperage rating, 600 Vac voltage rating, and a 300 kAIC interrupt capability at 600 Vac (100 kAIC at 300 Vdc). The time-delay, dual-element construction accommodates short, transient motor surges without nuisance trips, while still providing rapid fault clearance under fault conditions.
Yes. The product is designed for industrial control panels, motor drives, and power distribution devices. Its RK1 class profile, 60 A rating, and robust interrupt capacity make it well-suited for panels requiring high reliability, selective coordination, and quick fault isolation in automation environments.
The LPS-RK-60SPI fuse is CE marked, indicating compliance with European safety standards. It is built to RK1 class specifications and features a dual-element time-delay current-limiting design, supporting safe operation and regulatory alignment in modern automation projects.
The time-delay, current-limiting design reduces nuisance trips and energy waste, while the high interrupt rating enhances protection for upstream equipment. This translates to shorter maintenance windows, faster fault diagnosis with indicator options, and overall lower total-cost-of-ownership for panel assemblies and automated lines.
