Eaton LPJ-7SP Fuse - Class J Time-Delay, 300 kAIC
Part Number: LPJ-7SP
Quick Summary
Eaton LPJ-7SP fuse provides fast time-delay protection for electrical systems in industrial drives and motor circuits. This design reduces nuisance trips during motor starts and inrush events that can derail production schedules. CE marking and RoHS compliance help meet global safety and environmental standards, easing cross-border deployment. The Class J, dual-element current-limiting construction delivers reliable fault protection without false alarms, while ferrule end connections simplify installation in existing Bussmann-series panels. The compact form factor fits crowded control panels, reduces wiring complexity, and supports standard packaging for easy stocking. With a non-indicating indicator and high interrupt capability, the LPJ-7SP helps extend equipment life, lower maintenance costs, and improve overall line reliability.

Time-delay, dual-element current-limiting design delivers inrush tolerance and dependable fault protection, reducing nuisance trips and protecting motors, drives, and associated circuitry in conveyors and pumps. This translates to meaningful uptime gains and longer equipment life, while enabling predictable startup sequences and safer electrical environments. Class J construction and ferrule-end terminations simplify panel integration in standard control architectures, lowering installation risk and speeding commissioning in retrofit projects. The fuse’s non-indicating style minimizes panel clutter and avoids unnecessary visual indicators, helping technicians focus on critical diagnostics. With a 300 kAIC interrupt rating at 600 Vac and 100 kAIC at 300 Vdc, the LPJ-7SP provides robust fault clearing for power distribution and machine control across harsh industrial environments. The compact 2.25 in length and 0.81 in square footprint support dense panel layouts, enabling cost-efficient protection at the point of use. CE and RoHS compliance ensure global applicability and supply-chain confidence for OEMs and MROs alike.

FAQs
LPJ-7SP uses ferrule end-to-end terminations, a compact Class J footprint, and a non-indicating body. It fits standard control panels and retrofit installations, simplifying field termination and minimizing space. Ensure wiring complies with 600 Vac and 300 Vdc ratings and that the fuse is appropriately sized for the motor or drive load to avoid nuisance trips.
The LPJ-7SP provides 300 kAIC interrupt rating at 600 Vac and 100 kAIC at 300 Vdc, with a voltage rating of 600 Vac / 300 Vdc. This combination supports robust fault clearing for power and control circuits in industrial environments.
Yes. The time-delay, dual-element current-limiting design is specifically intended for inrush-tolerant protection, reducing nuisance trips during motor start-up while still delivering current-limiting protection during faults, which helps protect drive electronics and motors.
The LPJ-7SP is CE marked and RoHS compliant, supporting global regulatory requirements for safety, environmental impact, and electrical performance. This helps manufacturers and integrators meet international product-safety and sustainability standards without regional redesigns.
By reducing nuisance trips and extending motor life, the LPJ-7SP lowers unplanned downtime and maintenance costs. Its compact size and standard ferrule connections shorten installation time, while its high interrupt rating improves protection reliability, contributing to lower total cost of ownership in motor control panels.
