Eaton LPNRK10SPNP fuse - Class RK1, Time-delay 10A
Part Number: LPNRK10SPNP
Quick Summary
Eaton LPNRK10SPNP fuse provides time-delay, current-limiting protection for large distribution switchboards and motor control centers. Engineers often grapple with nuisance trips during motor startup and brief fault currents that disrupt production. RoHS compliant and built as a Class RK1 device, it meets modern regulatory expectations; for broader certification coverage, consult the manufacturer for UL/CSA listings. As part of the Eaton Bussmann family, it supports standardized stocking and straightforward cross-reference across panels. For panel builders and systems integrators, the compact 4.25 x 3.25 x 1.5 in form factor and nickel-plated caps deliver reliable protection plus ease of installation and maintenance planning.

Eaton Specification Sheet - LPNRK10SPNP
Time-delay, current-limiting protection reduces nuisance trips during motor startup and transient faults, improving line uptime and protecting costly drives. This leads to measurable production gains in large distribution switchboards and motor control centers, where startup surges are routine. The result is fewer unplanned outages and smoother commissioning. Nickel-plated caps provide enhanced corrosion resistance and reliable contacts in harsh or vibratory environments, extending fuse life and reducing maintenance costs. Class RK1 compatibility ensures easy cross-reference and stocking with the Bussmann series, streamlining procurement and panel design. RoHS compliant construction supports global installations and regulatory compliance, mitigating supply-chain risk. The 4.25 in length, 3.25 in height, and 1.5 in width deliver a compact footprint for crowded panels, while standard packaging simplifies logistics and field replacement. Non-indicating status aligns with conventional panel protection, letting external indicators or upstream controls manage diagnostics.

FAQs
The LPNRK10SPNP is designed for large distribution switchboards, power panelboards, and motor control centers. It follows the Bussmann series LPN-RK design, uses a Class RK1 construction, and fits standard Bussmann-style panels with a 4.25 in length, 3.25 in height, and 1.5 in width footprint. Ensure the system is RoHS compliant and verify clearance for 10 A protection.
Key specs include a 10 A amperage rating, time-delay current-limiting fuse type, non-indicating status, and nickel-plated caps. It is RoHS compliant and packaged in a standard format suitable for integration into large electrical assemblies and motor control centers.
Time-delay fuses tolerate brief inrush currents during motor starts and transient faults, reducing nuisance trips while still providing short-circuit protection. They are ideal in motor control centers and large switchboards where startup surges are common and precise protection coordination with upstream devices is required.
Yes, the LPNRK10SPNP is RoHS compliant. For additional certifications such as UL/CSA listings, refer to manufacturer documentation or contact Eaton for the current certification status, as the provided data lists RoHS but does not specify UL/CSA marks.
Nickel-plated caps enhance contact reliability and reduce corrosion-related maintenance. The Class RK1 design simplifies stocking and cross-referencing, lowering spare-part inventory. The time-delay rating minimizes downtime from startup surges, translating to improved equipment availability and potential energy savings in continuous-operation environments.
