Eaton LPS-RK-30SP Fuse - Time-Delay, Class RK1
Part Number: LPS-RK-30SP
Quick Summary
LPS-RK fuse from Eaton provides time-delay, current-limiting protection for power distribution circuits and motor loads. Engineers often grapple with nuisance tripping during inrush or fault events when using standard fuses, especially in drives and automation panels. This device is CE marked, and Eaton offers RoHS verification via its RoHS Search Tool to help with regulatory compliance. By combining a 30 A rating, a dual-element time-delay design, and high interrupt ratings, it supports reliable protection with reduced downtime. Its ferrule-end termination and electrically isolated end caps also simplify safe installation and straightforward field replacements, improving maintenance efficiency and panel safety.

FAQs
The LPS-RK-30SP is designed with ferrule-end x ferrule-end connections and a 5 inch length, making it compatible with standard fuse blocks, panelboards, and OEM enclosures that accommodate RK1 classified fuses. It supports safe, straightforward installation in control cabinets and motor drive panels, reducing retrofit complexity and downtime.
Key ratings include a 30 A current rating, voltage ratings of 600 Vac / 300 Vdc, and interrupt ratings of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc. It is a time-delay, dual-element fuse, offering reliable protection during motor inrush and short-term overloads while maintaining fast fault clearing.
Yes. Its time-delay, dual-element design minimizes nuisance tripping during startup surges common in motor drives and CNC equipment, while its high interrupt ratings ensure safe interruption of fault currents. This makes it well-suited for motor protection and other inrush-heavy loads in industrial settings.
The LPS-RK-30SP is CE marked, indicating compliance with European safety standards. For environmental and regulatory verifications, Eaton provides a RoHS verification resource (RoHS Search Tool) to confirm RoHS-related compliance for the product family and related components.
With a robust 30 A rating and high interruption capacity, the LPS-RK-30SP helps minimize unplanned downtime by reducing nuisance trips. Its non-indicating design simplifies panel integration, and the ferrule-end construction supports reliable long-term connections, contributing to lower maintenance labor costs and improved system availability.
