Eaton LPS-RK-15SPI fuse - Class RK1, 300 kAIC at 600 Vac
Part Number: LPS-RK-15SPI
Quick Summary
Eaton LPS-RK-15SPI fuse provides reliable overcurrent protection for industrial control panels and motor circuits. Industries struggle with nuisance fuse trips during inrush or startup, leading to downtime and costly repairs. The device is CE marked and conforms to Class RK1 protection, with RoHS verification available through Eaton's RoHS Search Tool. Its compact 5 in length with ferrule-end connections integrates easily into standard enclosures, while delivering a 15 A rating and a 300 kAIC interrupt capability at 600 Vac. This combination supports safer operation, faster fault isolation, and scalable protection for motor drives, power distribution, and automation panels, aligning with efficiency and maintenance goals.

Bussmann series Fuseology
Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, up to 600 A data sheet no. 1001
Feature: Time-delay, dual-element, current-limiting design. Business Impact: Enables reliable protection during motor startup and inrush events while limiting fault current to protect conductors and downstream devices. Application: Ideal for motor feeders, power supplies, and control circuits in industrial panels. Feature: High interrupt rating of 300 kAIC at 600 Vac (and 100 kAIC at 300 Vdc). Business Impact: Withstands severe short-circuit events, reducing equipment damage and unscheduled downtime. Application: Critical in high-energy panels and distributed power systems where fault currents exceed standard ratings. Feature: Class RK1 designation with ferrule end x ferrule end connections. Business Impact: Facilitates fast, reliable installations in standard Bussmann RK1 housings and existing panel architectures. Application: Retrofit or new-build control panels and machine centers requiring proven RK1 protection. Feature: Indicating vs non-indicating fuse options (With Indicator). Business Impact: Visual status indication accelerates maintenance planning and reduces investigative downtime. Application: Safety-critical panels where quick confirmation of fuse health matters. Feature: Compact form factor and standard packaging (5 in length, 0.81 in x 0.81 in, 1.6 lb; quantity 10). Business Impact: Simplifies logistics, stocking, and field replacements, lowering total cost of ownership. Application: OEMs and integrators stocking routine spare parts for industrial environments.

FAQs
The LPS-RK-15SPI uses ferrule-end x ferrule-end connections and fits standard RK1 assemblies. With a 5 in length and a compact 0.81 x 0.81 in footprint, it installs into typical panel boards quickly. Ensure the fuse is rated for 15 A and that panel bussing matches ferrule dimensions for secure termination.
Key ratings include 15 A amperage, 600 Vac voltage rating, and a 300 kAIC interrupt rating (100 kAIC at 300 Vdc). It is a time-delay, dual-element, current-limiting fuse designed for motor feeders and industrial power circuits, combining fast fault clearing with startup tolerance.
Yes. The time-delay, dual-element design handles inrush during motor start while limiting fault current, reducing nuisance trips and protecting conductors. Its RK1 class and high interrupt rating make it suitable for motor feeders and drive applications in industrial environments.
The LPS-RK-15SPI options include an indicating fuse. This provides a visual status cue, enabling faster on-site diagnostics and reducing time spent verifying protection status during maintenance or outages.
The product is CE marked, aligning with essential European safety standards. RoHS verification can be checked via Eaton's RoHS Search Tool, supporting compliance and procurement workflows. Catalogs and data sheets are available for detailed specifications and application guidance.
