Eaton LPN-RK-2SP Fuse - CE Marked RK1 Time-Delay
Part Number: LPN-RK-2SP
Quick Summary
Eaton LPN-RK-2SP fuse protects motor circuits in industrial automation applications. Inrush surges and nuisance trips can disrupt startups and erode uptime, making reliable protection essential. CE marking signals global compliance, while the Class RK1, dual-element time-delay design provides robust current-limiting performance across 250 Vac and 125 Vdc. With ferrule-end connections, a compact 2 in length, and non-indicating status, the LPN-RK-2SP integrates cleanly into standard control panels, helping shorten installation time and reduce service calls. This fuse combines safety, performance, and ease of procurement to support manufacturing reliability and total cost of ownership goals, while offering a clear path to motor protection and panel protection strategy.

Bussmann series Low-Peak 250 V LPN Class RK1 time-delay fuses,1/10-60 A data sheet no. 1003
Time-delay, dual-element protection delivers robust current-limiting performance while absorbing normal motor inrush. This reduces nuisance trips during startup and supports smooth operation in conveyors, pumps, and machine tools. The 2 A rating paired with 250 Vac and 125 Vdc operation makes it a versatile choice for mixed-voltage panels, lowering stocking needs and simplifying procurement. High interrupt ratings of 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc enable rapid fault interruption, safeguarding downstream components and reducing repair costs after faults. Class RK1 compatibility and ferrule-end connections streamline retrofits and new installations alike, while the compact 2 in length, 0.56 in width, and 0.56 in height fit compact control enclosures. Standard packaging of 10 pieces per pack supports efficient field replenishment. Non-indicating status helps keep panel boards uncluttered, while high inrush motor protection is a highlighted feature for demanding industrial drives.

FAQs
Yes. The LPN-RK-2SP uses ferrule-end x ferrule-end connections and fits within a standard 2 in length housing. With ferrule-end terminals and a compact footprint (0.56 in x 0.56 in), it installs easily in common control panels and motor control centers, minimizing wiring changes and panel rework.
The fuse is time-delay with dual elements and offers 2 A rating, 250 Vac and 125 Vdc voltage ratings, and 300 kAIC interruption at 250 Vac or 100 kAIC at 125 Vdc. It is designed to tolerate motor inrush while providing rapid fault interruption, reducing nuisance trips and protecting downstream equipment.
Yes, the LPN-RK-2SP is CE marked, indicating compliance with applicable European standards. For other global certifications, confirm panel-level approvals and regional requirements, as additional certifications may be needed depending on the installation location and end-use environment.
Ideal for motor protection in control panels, motor drives, conveyors, pumps, and machine tools. Its time-delay characteristic handles startup surges, while the current-limiting capability protects wiring and contactors from excessive fault currents, improving uptime and reducing unplanned downtime.
With non-indicating status, rely on external diagnostics or panel monitoring to confirm fuse health, reducing false indicators in the field. Its durable RK1 class design and dual-element construction extend replacement intervals, lowering maintenance costs and ensuring consistent protection across compressors, fans, and drives.
