Time-delay, dual-element current-limiting design reduces nuisance trips by tolerating motor inrush while still delivering fast fault interruption, decreasing unplanned downtime and maintenance costs in motor-driven applications. This results in improved equipment availability and predictable protection in conveyors, pumps, and presses. Its 17.5 A rating and 600 Vac operating voltage cover common motor control scenarios in automated lines, enabling safer, reusable protection across multiple panels. The 300 kAIC interrupt rating at 600 Vac provides robust short-circuit protection in high-current fault conditions, supporting safer panel designs and regulatory compliance. Ferrule-end connections simplify field installation and ensure reliable contact integrity, while compact dimensions (2.25 in length, 0.81 in width and height) assist in tight control cabinet layouts. The unit’s Class J, time-delay, dual-element construction is compatible with low-voltage branch circuit fuses and motor protection schemes, reducing total cost of ownership. Its RoHS and CE compliance further support European manufacturing requirements and environmental responsibility.

FAQs
The LPJ-17-1/2SPI uses ferrule-end connections and is designed for low-voltage branch circuits in motor control panels. It supports Class J protection with a 17.5 A rating and a 600 Vac maximum, making it suitable for standard motor drives, conveyors, and line-start equipment within automation configurations.
The time-delay aspect tolerates inrush currents common to motors while still limiting fault current, reducing nuisance trips during startup. The dual-element design speeds interruption of actual faults, which minimizes unplanned downtime and extends equipment life by preventing cascading faults in drives and power distribution networks.
Yes. The LPJ-17-1/2SPI is CE marked and RoHS compliant, ensuring compliance with European safety directives and environmental standards. This supports straightforward integration into European manufacturing lines and reduces compliance risk for regulated facilities.
Ideal applications include motor protection in control panels, drive systems, and power distribution within manufacturing and processing facilities. Its Class J rating, 600 Vac operation, and 300 kAIC interrupt capacity make it suitable for moderate to high fault currents in automated lines, while its ferrule ends ease field and panel mounting.
The LPJ-17-1/2SPI provides predictable protection with reduced nuisance trips, leading to lower maintenance windows and higher line availability. Its robust interrupt rating and compliance features support longer service intervals, standardized spares, and streamlined procurement, delivering total cost of ownership savings across automation projects.
