Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, 70-600 A data sheet no. 1002
Feature → Business Impact → Application: Time-delay, dual-element, current-limiting design reduces nuisance trips and improves selective coordination in motor and power circuits, delivering stable protection with minimized arc energy and faster fault clearance. This translates to lower maintenance downtime and extended equipment life in manufacturing lines and process plants, where reliability directly affects output. Application: Ideal for control panels and feeder loads in industrial automation. Feature → Business Impact → Application: Class RK1 construction and blade-end connections enable quick upgrades in existing RK1 footprints, reducing installation time and field errors during panel modernization. Application: Replacement in standard Bussmann RK1 assemblies across machine builds and industrial facilities. Feature → Business Impact → Application: High interrupt rating (300 kAIC at 600 Vac, 100 kAIC at 300 Vdc) provides robust protection for high-energy faults, enabling safer startups and lower incident costs in conveyors, presses, and packaging lines. Feature → Business Impact → Application: Electrically isolated end caps enhance safety during maintenance, limiting touch potential and simplifying service work in crowded electrical rooms. Feature → Business Impact → Application: 600 Vac / 300 Vdc rating and 13.38 in length support compatibility with established power distribution schemes, enabling seamless stocking and predictable lead times for procurement teams. Feature → Business Impact → Application: Non-indicating status reduces component complexity and is compatible with externally monitored protection schemes where indicators are integrated at the system level. Overall, this fuse supports cost-efficient, compliant protection across energy-intensive applications while aligning with CE and RoHS compliance expectations.

FAQs
The LPS-RK-600SP uses blade end x blade end connections and belongs to the Class RK1 family, making it compatible with standard RK1 panel layouts. Its 13.38 inch length, 2.88 inch width, and 2.88 inch height match common footprint requirements, enabling straightforward upgrades and minimal field modification during installation.
Key specs include a 600 A amperage rating, 600 Vac / 300 Vdc voltage rating, dual-element time-delay construction, and a 300 kAIC interrupt rating at 600 Vac (100 kAIC at 300 Vdc). The fuse is non-indicating and features a 1 piece packaging with electrically isolated end caps for safe handling.
Yes. The time-delay, current-limiting RK1 fuse is designed to handle motor fault currents and inrush events while providing selective coordination with upstream protection. Its high interrupt rating and dual-element construction help prevent nuisance blowing during startup transients, supporting reliable motor protection in automated lines and conveyors.
The LPS-RK-600SP is CE-marked, ensuring compliance with European safety directives. For regulatory substance limits, RoHS compliance guidance is available via Eaton’s RoHS Search Tool, helping procurement verify environmental conformity in global supply chains.
The non-indicating design reduces display complexity, while the time-delay, current-limiting features minimize nuisance trips, lowering downtime and service visits. Its robust 600 A / 600 Vac rating and easy RK1 replacement path contribute to reduced spare parts inventory and faster recovery for high-demand lines, delivering measurable uptime and cost savings over time.
