Eaton Specification Sheet - LPNRK20SPNP
Time-delay, current-limiting protection minimizes nuisance trips during motor starts and inrush events, reducing downtime and extending downstream equipment life in large distribution switchboards and power panelboards. Nickel plated caps provide enhanced corrosion resistance, lowering maintenance needs and ensuring stable contact reliability in harsh environments. The Class RK1 designation guarantees compatibility with standard Bussmann series fuses, speeding procurement and installation in control cabinets. The 20 A rating supports safe protection of typical automation loads while offering headroom for startup surges, improving coordination with upstream devices. Non-indicating design keeps panels clean and straightforward to inspect during maintenance. RoHS compliance aligns with modern regulatory expectations, and standard packaging accelerates stocking and field replacements for retrofit and new builds. Overall, the LPNRK20SPNP integrates smoothly into Bussmann-led protection strategies, enabling predictable performance and lower total cost of ownership.

FAQs
The LPNRK20SPNP is designed for Eaton Bussmann series fuse blocks used in large distribution switchboards, power panelboards, and motor control centers. It fits standard RK1 protection footprints and 3x11 panel spaces, enabling straightforward retrofits or new installs. Ensure correct mounting in compatible fuse holders and verify panel ratings match the device specifications for safe, reliable operation.
Expect dependable protection with selective coordination in normal operation and during startup surges. The time-delay feature tolerates temporary inrush currents without tripping, while the current-limiting capability limits short-circuit energy, helping protect downstream transformers, drives, and wiring. This balance reduces downtime and extends component life in automation panels and motor control centers.
Yes, the LPNRK20SPNP is RoHS compliant, supporting regulatory alignment for modern plants. It is designed as a Class RK1 fuse, compatible with standard Bussmann series protection schemes. For other regional certifications (such as CE/UL listings), consult Eaton's specification sheet or contact the manufacturer to confirm availability and documentation for your facility’s compliance requirements.
RoHS compliance is documented for the LPNRK20SPNP. For additional certifications such as CE or UL listings, refer to Eaton's official specification sheet or contact Eaton directly. Certification availability can vary by lot and regional requirements, so confirm current listings with the manufacturer before large-scale deployments in regulated environments.
The fuse features nickel plated caps for improved durability, a standard 3 in length and 11 in height footprint, and standard packaging, all of which simplify stocking and installation alongside other Bussmann series devices. Compatibility with RK1 class fusing reduces integration risk in existing protection schemes and accelerates project timelines for retrofits and new builds alike.
