FAQs
Yes. The LPS-RK-10SPI uses ferrule-end terminations (ferrule end x ferrule end), which aligns with standard RK1 fuse holders and panel buses. Its 5 in length and dual-element construction suit common industrial enclosures, enabling straightforward removal and replacement in existing Bussmann RK1 layouts. Ensure mating hardware supports ferrule conductors of the appropriate gauge and follow Eaton's mounting guidelines for safe, reliable operation.
Key ratings include a 10 A amperage rating, a 600 Vac maximum voltage, and an interrupt rating of 300 kAIC at 600 Vac (100 kAIC at 300 Vdc). The device is designed as a time-delay, current-limiting fuse with a dual-element configuration, providing reliable protection for circuits prone to startup surges. This combination supports safe operation in demanding industrial environments.
Time-delay RK1 fuses excel in motor control, conveyors, and power-distribution panels where startup inrush and short-circuit hazards coexist. The 10 A rating and 600 Vac capability enable selective coordination with upstream protection devices, reducing full-system outages while preserving downstream components. Use in control cabinets and machine enclosures to extend component life and simplify maintenance in manufacturing settings.
CE marking on the LPS-RK-10SPI indicates conformity with European safety standards; Bussmann RK1 products typically align with industry installation codes. Specific SIL or IP ratings are not listed in the data, and RoHS status is accessible via Eaton's RoHS tool. For procurement, verify your regional compliance requirements and consult the latest Eaton datasheet to confirm certifications for your application.
Using the LPS-RK-10SPI reduces maintenance and downtime by limiting nuisance trips during motor start-ups while delivering fast fault clearing during faults. Its compact 5 inch form, standard ferrule terminations, and clear indicator options help technicians quickly locate blown fuses, simplifying replacement. Over time, this translates into fewer outages, lower maintenance costs, and longer equipment life in industrial facilities.
