Feature → Business Impact → Application: The LPN-RK-5SP uses a time-delay, dual-element design to tolerate inrush currents while preserving protective limits, reducing nuisance trips and unplanned downtime in motor control and power distribution circuits. This translates to improved line uptime and longer equipment life in machine bays and control cabinets. Application: ideal for compressors, conveyors, pumps, and automation panels where inrush events are common. Feature → Business Impact → Application: With a 5 A amperage rating and a 250 Vac / 125 Vdc voltage rating plus 300 kAIC/100 kAIC interrupt capability, it provides robust fault current protection without sacrificing selectivity, enabling safer panel layouts and easier coordination with upstream protection. Application: protection for feeders and control circuits in OEM equipment. Feature → Business Impact → Application: Class RK1, ferrule end x ferrule end connections, and electrically isolated end caps simplify installation and maintenance, reducing field rework and improving safety during fuse replacement. Application: retrofit projects and new build-outs in electrical protection schemes. Feature → Business Impact → Application: Non-indicating design minimizes maintenance inputs while providing clear circuit protection information through panel indicators, supporting clean maintenance logs and audit readiness. Application: industrial control panels requiring minimal visual intrusion. Feature → Business Impact → Application: Pack quantity and standard packaging streamline stocking and procurement, enabling just-in-time inventory for maintenance teams and distributors. Application: high-volume automotive or packaging machinery lines with frequent fuse replacements.

FAQs
The LPN-RK-5SP uses ferrule end x ferrule end connections and a compact 2 in length with a 0.56 in width/height, enabling straightforward drop-in replacement in standard control panels. Its electrically isolated end caps simplify safe maintenance and reduce the risk of accidental contact, while maintaining compatibility with Bussmann series protection schemes.
This fuse is rated for 5 A with a voltage rating of 250 Vac / 125 Vdc, and provides an interrupt rating of 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc. The time-delay, dual-element design supports inrush tolerance while maintaining current-limiting protection, making it suitable for motors and other inductive loads in protective assemblies.
Yes. The time-delay, dual-element characteristics of the LPN-RK-5SP allow it to absorb initial surge without nuisance tripping, while still delivering rapid interruption during fault conditions. This makes it well-suited for motor control circuits, conveyors, pumps, and other inductive loads common in automation equipment.
The LPN-RK-5SP is CE Marked, signaling compliance with European safety directives. It is classified as Class RK1, confirming its fuse family and performance characteristics. These certifications support regulatory compliance for European installations and help ensure consistent protection across systems.
With a robust 300 kAIC interrupt rating and non-indicating design that reduces maintenance inputs, the LPN-RK-5SP minimizes unscheduled trips and simplifies spare parts management. Its compact form and ferrule-ended connections speed up installation, lowering commissioning time and contributing to reduced downtime and total cost of ownership in fielded protection schemes.
