Eaton LPJ-12SPI Fuse - Class J RoHS, CE Certified
Part Number: LPJ-12SPI
Quick Summary
LPJ-12SPI fuse is a Class J time-delay, dual-element device that protects motors and control circuits in industrial panels. It addresses the common challenge of nuisance tripping during motor startup by combining selective, fast-acting protection with a controlled inrush response. This fuse carries RoHS compliance and CE marking, supporting global deployment and regulatory alignment. With a 12 A rating and a 300 kAIC interrupt rating at 600 Vac, it delivers robust short-circuit protection while staying compatible with 600 Vac control schemes. Using this part simplifies procurement for compliance-heavy applications and supports reliable plant uptime while enabling efficient motor protection and circuit protection strategies.

LPJ-12SPI employs a time-delay, dual-element current-limiting design to protect motors and control circuits without nuisance trips during startup. This selective protection approach lets motors ramp into operation while rapidly clearing faults, reducing downtime in demanding applications such as conveyors, presses, and packaging lines. By balancing inrush tolerance with short-circuit resilience, it supports more reliable machine performance in modern automation cells. With a 12 A rating and a 300 kAIC interrupt rating at 600 Vac, the LPJ-12SPI provides a strong fault-clearance margin for high-current events typical in industrial power distribution. The 600 Vac, 300 Vdc voltage rating allows use in mixed AC/DC panels, while ferrule-end terminations ensure a robust, vibration-resistant connection. This combination reduces panel heat and improves long-term reliability in motor feeders and drive sections. The part's RoHS compliance and CE marking simplify global procurement and regulatory compliance for multinational plants. The Class J designation identifies the fuse geometry and application range, while the dual-element construction supports sustained protection in heavy-duty environments. For maintenance teams, available indicators aid quick status checks without opening enclosures, helping to maintain uptime in critical line-side protections. Installing LPJ-12SPI is straightforward in standard Bussmann LPJ fuse holders thanks to the ferrule-end connections and the compact 2.25 in length with 0.81 in width and height. Its standard packaging and compatibility with the LPJ series streamline stocking and replacement, reducing on-site downtime and support costs in routine panel revisions. By aligning with the Bussmann LPJ family, this fuse benefits from tested compatibility with common control panels, switchgear, and motor starters, including the ability to coordinate with upstream protection devices. Engineers can specify a single LPJ-12SPI for multiple lines, achieving economies of scale and simplifying spares inventories.

FAQs
LPJ-12SPI features ferrule-end terminations and a compact 2.25 in length, designed to fit standard Bussmann LPJ fuse holders. The 0.81 in width and height ensure reliable, vibration-resistant connections in motor feeder panels. Installation is straightforward, with a robust termination that tolerates industrial enclosures and panel dynamics while preserving low contact resistance for long service life.
LPJ-12SPI provides a time-delay, dual-element current-limiting design rated at 12 A, with a 300 kAIC interrupt capacity at 600 Vac. This combination supports high inrush typical of motor starts while delivering fast fault clearing for short-circuit events. It reduces nuisance trips during startup and protects downstream equipment, switchgear, and drives in industrial environments.
Yes. The LPJ-12SPI is RoHS compliant and CE marked, enabling global procurement without regional compliance hurdles. These certifications help streamline regulatory approvals, particularly for multinational facilities and projects that must meet European and RoHS requirements, while maintaining consistent protection across lines.
Ideal for motor feeders, drives, and machine control circuits in industrial automation, the LPJ-12SPI supports high inrush loads and demanding duty cycles. It is well-suited for control panels, motor control centers, and drive architecture where reliable short-circuit protection and controlled inrush handling improve system uptime and equipment life.
The time-delay characteristic minimizes nuisance trips during motor starts, improving line availability. The high interrupt rating protects feeders and downstream devices, reducing replacement costs after faults. If an indicator option is used, maintenance staff can confirm fuse status quickly, lowering labor time during routine checks and spares stocking, which translates to lower total cost of ownership.
