Eaton LPN-RK-25SP fuse - Class RK1, 25 A, 300 kAIC

Time-delay, dual-element design provides robust protection for motor loads by tolerating brief overloads and inrush currents. The business impact is fewer nuisance trips and safer start-up sequences, which translates into higher equipment uptime and lower maintenance intervention. This is especially beneficial in pump, fan, and conveyor applications where motors see repeated surges during start and load changes. With a 25 A amperage rating and 250 Vac/250 Vdc voltage rating, the LPN-RK-25SP is compatible with a wide range of control circuits and motor starters. The application impact is straightforward wiring and predictable protection curves for panel builders, reducing design time and minimizing rework in new installations. The fuse offers a high interrupt rating of 300 kAIC at 250 Vac and 100 kAIC at 250 Vdc, ensuring safe disconnection in the event of a short circuit. For operators, this means improved safety margins and faster fault clearance, which is critical in power-dense production lines. Class RK1 designation and ferrule-end x ferrule-end connection simplify selection and installation. At 2 in length and 0.56 in width, the device fits compact enclosures, while the 0.5 lb weight keeps panel load minimal and supports easy replacement during maintenance. Non-indicating design paired with noted features like 'high in-rush current motor protection' reduces visual clutter while still providing clear protection when tested or measured electrically. The data sheet’s '8 sec at 500%' response profile helps engineers model protection alongside operation envelopes. In practice, adopting this fuse can yield measurable efficiency gains, lower risk of unexpected outages, and a consistent protection strategy across machine fleets, contributing to total cost of ownership improvements.
