FAQs
The LPN-RK-80SPI is a Class RK1 dual-element, time-delay fuse designed for standard RK1 holders used in Bussmann/Eaton protection schemes. It measures 5.88 in long with 1.1 in width and height, and features electrically isolated end caps for safer installation. Ensure the panel or enclosure supports 250 Vac circuits and that the holder is rated for the device’s interrupt capability (300 kAIC at 250 Vac).
Key specs include an 80 A amperage rating, 250 Vac (also 250 Vdc) voltage rating, and a 300 kAIC interrupt rating at 250 Vac, with 100 kAIC at 250 Vdc. It is a time-delay, current-limiting fuse with dual elements, designed to tolerate inrush while protecting wiring and components from short circuits.
Yes. The 80 A, 250 Vac rating combined with time-delay, dual-element design and high interrupt capability makes it well-suited for motor starters, conveyors, and other motor control applications where inrush is common. Its Class RK1 compatibility and CE marking help ensure compliance in common industrial panel builds.
The LPN-RK-80SPI is CE marked, reflecting compliance with European safety and environmental directives. It is a Class RK1 fuse with a dual-element, time-delay design and electrically isolated end caps for safe handling. For broader RoHS considerations, utilize Eaton’s RoHS search tool as needed to verify current status in your region.
Using the LPN-RK-80SPI minimizes unplanned downtime by tolerating inrush events while quickly interrupting faults, reducing downstream damage. Its 5.88 in length and standard RK1 form factor simplify installation, while the 80 A rating supports typical mid-range loads, delivering reliability, safety, and improved maintenance intervals for long-term cost savings.
