Eaton LPN-RK-8/10SP Fuse - Class RK1 Time-Delay
Part Number: LPN-RK-8/10SP
Quick Summary
The Eaton LPN-RK-8/10SP fuse is a time-delay protection device for industrial control circuits. Nuisance trips during motor starts and surge events can compromise uptime, especially in compact panels. CE Marked and Class RK1 compliant, with dual-element construction and electrically isolated end caps, it delivers robust protection in harsh environments. OEMs and panel builders gain predictable performance, reduced nuisance tripping, and easier component replacement, helping streamline maintenance and spare-part management while meeting stringent safety and compliance requirements. By combining a compact 2 in body with a 0.8 A rating and high interrupt ratings, it fits tight installations without sacrificing protection.

Bussmann series Low-Peak 250 V LPN Class RK1 time-delay fuses,1/10-60 A data sheet no. 1003
Time-delay, dual-element design provides inrush tolerance and current-limiting protection, reducing nuisance trips during motor starts and surge events. This translates to improved panel uptime and longer equipment life in demanding environments; ideal for industrial control panels and power-distribution blocks. The 0.8 A amperage rating paired with a 250 Vac/125 Vdc voltage rating enables cross-region compatibility, supporting European and US panel designs while maintaining tight protection. Interrupt ratings of 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc ensure robust fault protection for high-energy systems, minimizing collateral damage and maintenance costs. The compact 2 in length, along with 0.56 in width and height, supports dense panel layouts and easier replacement in crowded enclosures. Electrically isolated end caps simplify safe installation and service, reducing wiring errors. Non-indicating design lowers status-monitoring complexity in harnessed assemblies, while CE compliance ensures global deployment. These features combine to deliver reliable, economical circuit protection for OEMs and integrators.

FAQs
Install the fuse in a compatible Bussmann/LPN RK1 fuse holder, ensuring the 2 in body fits the enclosure and is properly seated. Connect to the circuit per the panel diagram, verify voltage rating (250 Vac / 125 Vdc), and confirm the electrically isolated end caps are secure. Use proper PPE and observe clearance to prevent arcing; replace only with identical LPN-RK-8/10SP units.
Amperage rating is 0.8 A; voltage rating is 250 Vac / 125 Vdc. Interrupt ratings are 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc. The fuse provides time-delay protection with a response time of about 8 seconds at 500% overload, making it suitable for controlled inrush events and short-term surges in motor and control circuits.
Yes. The LPN-RK-8/10SP is a dual-element, time-delay fuse designed to tolerate motor inrush while protecting circuits from sustained faults. Its Class RK1 family and 0.8 A rating provide a balanced level of protection for small motors and control circuits, reducing nuisance trips during startup while delivering reliable interruption during faults.
The fuse is CE marked and belongs to the Class RK1 protection family, with non-indicating indicators and electrically isolated end caps. These features support global deployment in compliant systems and safer maintenance procedures, aligning with common international electrical protection standards.
The dual-element, time-delay design reduces nuisance trips and protects against costly motor faults, leading to fewer panel resets and less downtime. Its compact form factor and standardized RK1 family simplify stocking and replacements, improving spare-parts management. Overall, expect lower maintenance costs and improved uptime in protected industrial circuits.
