Time-delay, dual-element design delivers current-limiting protection that tolerates motor inrush while preserving fault clearance. This results in fewer nuisance trips and extended motor life in conveyor systems and pumps used across manufacturing floors. The 0.1 A amperage rating enables precise safeguarding of control panels and sensing circuits, reducing mis-trips and extending the life of sensitive automation equipment in instrumentation and control applications. With a high interrupt rating—300 kAIC at 250 Vac and 100 kAIC at 125 Vdc—faults are cleared rapidly, protecting downstream drives and minimizing collateral damage in industrial machinery. The RK1 class designation and non-indicating construction simplify replacement and panel integration, supporting compact layouts in motor starters and control enclosures. Standard packaging (10 per pack) and a 2 in length ensure straightforward procurement and stocking for maintenance teams and OEMs. These features translate to measurable improvements in uptime, safety, and total cost of ownership for electrical protection systems across manufacturing and process industries.

FAQs
To install the LPN-RK-1/10SP, ensure the fuse is the correct amperage (0.1 A) and that the circuit voltage matches 250 Vac or 125 Vdc as rated. Mount in a standard Bussmann RK1 fuse holder or fuse block, insert with proper polarity, and secure with the enclosure hardware. Verify tight connections and test continuity after installation to confirm protection is in place and ready for operation.
Key ratings include an amperage rating of 0.1 A, voltage rating of 250 Vac / 125 Vdc, and interrupt ratings of 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc. The fuse is time-delay and dual-element, designed for motor protection with current-limiting characteristics to handle inrush without nuisance tripping.
Yes. The time-delay, dual-element design provides inrush tolerance while still delivering fast fault clearance, making it well suited for motors, conveyors, and drives that experience short startup surges. This helps reduce unnecessary downtime and wear on electrical equipment while maintaining robust protection.
The LPN-RK-1/10SP is CE Marked, indicating EU safety compliance. It is a Class RK1 fuse, aligning with Bussmann RK1 standards for protection in low-voltage circuits. These validations support regulatory alignment and reputable protection performance in industrial applications.
