Eaton LPJ-35SPI Fuse - Class J Time-Delay, 600 Vac, 300 kAIC
Part Number: LPJ-35SPI
Quick Summary
The Eaton LPJ-35SPI fuse protects motor drives and control panels from overcurrent with reliable, time-delay protection. Users often face nuisance trips during motor startup and high inrush, leading to unexpected downtime and maintenance costs. CE marked and RoHS compliant, this Class J, dual-element current-limiting device delivers robust protection at 600 Vac with a 300 kAIC interrupt rating, while supporting easy integration into standard control architectures. Built for industrial protection, it aligns with ferrule-end connections and offers indicating or non-indicating options, helping you optimize reliability and total cost of ownership across motor control centers and drive assemblies.

FAQs
Install the LPJ-35SPI using standard ferrule-end connections, ensuring the fuseholder aligns with Class J mounting guidelines. Verify the circuit is de-energized, insert the dual-element, current-limiting device with correct polarity, and confirm the indicating or non-indicating option chosen matches your control scheme. The 2.38 in length, 1 in height, and 1 in width fit common fuse blocks, facilitating quick retrofits or new panel builds.
The LPJ-35SPI combines time-delay operation with dual-element current-limiting, enabling controlled response during startup transients while still interrupting faults quickly. This reduces nuisance trips and protects motors against overcurrent without sacrificing startup performance, making it ideal for drives, conveyors, and pump applications where high inrush is common.
Yes. The LPJ-35SPI is CE marked and RoHS compliant, ensuring it meets European regulatory requirements for environmental and safety standards. This compatibility supports compliant procurement and installation across European facilities and aligns with multi-site engineering specifications.
A 300 kAIC interrupt rating indicates the fuse can interrupt extremely high fault currents without sustaining damage, protecting downstream equipment and improving safety during short-circuit events. This is particularly important in power-heavy motor circuits and switchgear where fault levels can spike rapidly.
Choose the LPJ-35SPI with the appropriate end configuration (ferrule end x ferrule end) and indicator preference to suit your monitoring needs. Pair it with compatible Bussmann LPJ data sheets and catalogs for proper coordination with upstream protection devices, enabling faster maintenance, reduced stocking complexity, and lower total cost of ownership across fleets.
