Eaton LPJ-2-1/2SP Fuse - Class J Time-Delay Current-Limiting
Part Number: LPJ-2-1/2SP
Quick Summary
The Eaton LPJ-2-1/2SP fuse provides time-delay protection for motors and control circuits in industrial gear. Engineers often battle nuisance trips and mis-specified protection that leads to motor damage and downtime. CE marking and RoHS compliance, together with Class J and a dual-element current-limiting design, deliver reliable, safe operation. This fuse streamlines protection in panel builds and reduces total cost of ownership, with compatibility for ferrule-term connections and standard packaging. Designed for control panels, motor starters, and in-line circuits, it accepts 2.5 A loads at 600 Vac and handles peak current surges with time-delay protection.

FAQs
Install the LPJ-2-1/2SP with ferrule end terminations for quick, secure connections. Confirm the circuit is within the 2.5 A rating and 600 Vac voltage range. Use proper panel mounting practices and ensure compatible bus bar spacing to prevent overheating. The dual-element design supports reliable protection in motor control centers and inline circuits.
The time-delay, dual-element current-limiting design accommodates motor inrush without nuisance tripping, while providing fast interruption for faults. This enables smoother motor start-up, protects winding insulation, and reduces wear on contactors, delivering improved motor life and reduced downtime in conveyors, pumps, and fans.
Yes. The LPJ-2-1/2SP fuse is CE marked and RoHS compliant, aligning with regulatory requirements for European setups and environmentally responsible manufacturing. This simplifies compliance documentation for panel builds and helps with supplier qualification processes in regulated industries.
LPJ-2-1/2SP offers 300 kAIC interrupt rating at 600 Vac and 100 kAIC at 300 Vdc, with an amperage rating of 2.5 A and voltage ratings of 600 Vac / 300 Vdc. It uses a time-delay, current-limiting design and features dual elements for reliable fault interruption in demanding electrical protection schemes.
With a compact 0.1 lb weight and standard packaging, replacement and stocking are straightforward, reducing downtime during maintenance. The 2.5 A rating plus high interrupt capability supports longer motor life and fewer nuisance trips, delivering lower total cost of ownership in production lines and automated systems.
