Eaton LPJ-2-1/4SP Fuse - Class J, CE RoHS Compliant
Part Number: LPJ-2-1/4SP
Quick Summary
The Eaton LPJ-2-1/4SP fuse provides time-delay protection for motor starters and power circuits. Nuisance trips during inrush or mis-specified protection can drive uptime losses and maintenance costs, so reliable coordination matters. With CE marking and RoHS compliance, this Class J fuse aligns with regulatory and environmental requirements, while its dual-element current-limiting design delivers dependable motor protection. Its compact footprint, non-indicating status, and high in-rush protection help reduce spare parts and simplify service life. Designed for industrial environments, it supports predictable performance across motor control and power-distribution panels.

FAQs
LPJ-2-1/4SP uses ferrule-end connections and a compact footprint, making it readily interchangeable with standard Class J fuses in motor starter panels. The 0.81 in length and 0.81 in width fit typical DIN-rail and cabinet layouts, while the 2.25 A rating suits small to medium motor control loads. This facilitates quick swaps during maintenance and retrofit projects without voltage or wiring rework.
The fuse features time-delay operation and a dual-element current-limiting design, which accommodates motor inrush without triggering unnecessary trips. It preserves circuit protection while allowing accelerated equipment startup, reducing downtime due to fuse nuisance trips in applications such as pumps, fans, and conveyors.
This LPJ fuse is CE Marked and RoHS Compliant, signaling adherence to European electrical standards and restricted hazardous substances. For manufacturers, this simplifies regulatory approvals and supports sustainability goals, while end users benefit from compatible, compliant equipment across global installations.
The LPJ-2-1/4SP is rated at 2.25 A with voltage ratings of 600 Vac and 300 Vdc. It provides an interrupt rating of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, ensuring robust fault clearance for motor control circuits and power distribution panels in harsh industrial environments.
Using LPJ fuses reduces downtime from nuisance trips thanks to its time-delay, dual-element design, while its non-indicating status minimizes false indicators during inspections. The standard ferrule-end construction and compact size ease replacements and stock management, delivering lower maintenance costs and predictable ROI in motor protection schemes.
