Time-delay, dual-element design reduces nuisance trips during motor inrush, enhancing system uptime. By differentiating peak and continuous currents, it protects wiring and drives without sacrificing start-up performance. This translates to fewer unplanned shutdowns in conveyors, pumps, and fans. With a 300 kAIC interrupt rating at 600 Vac, LPJ-150SPI quickly clears faults, protecting feeders and downstream equipment and reducing the risk of cascading failures in large drives and critical loads. The indicating option speeds fault location for maintenance teams, minimizing downtime and service costs. Its 2.25 inch body length and bolted blade end connections enable secure mounting in standard enclosures, while standardized packaging supports efficient stocking and faster replacement. CE marking and RoHS compliance ensure regulatory alignment, supporting cross-border procurement and sustainable engineering practices. Overall, LPJ-150SPI enhances reliability, supports scalable automation architectures, and lowers total cost of ownership in industrial facilities.

FAQs
LPJ-150SPI uses bolted blade end connections and a compact 2.25 inch body, so install it in standard Class J fuse blocks or holders designed for dual-element, time-delay fuses. Ensure proper panel clearance and alignment to avoid binding during replacement. If your panel supports the indicating version, select that option to speed fault location.
The fuse employs a time-delay, dual-element design that tolerates motor inrush without tripping. It provides a 10-second response window at around 500 percent overload, enabling reliable motor start-up while still protecting circuits from sustained faults. This balance reduces nuisance trips and supports smooth operation of drives and conveyors.
Yes. LPJ-150SPI is rated for 600 Vac with a 150 A current rating and a 300 kAIC interrupt rating at 600 Vac, plus a 100 kAIC rating at DC. This combination protects feeders and downstream equipment in high-energy control circuits, while delivering fast fault clearance in short-circuit events.
LPJ-150SPI carries CE marking and RoHS compliance, signaling conformity with European product safety and environmental standards. These certifications facilitate cross-border procurement, support regulatory acceptance in global installations, and help ensure that motor protection devices meet both performance and sustainability requirements.
Deploying LPJ-150SPI typically reduces downtime by minimizing nuisance trips during motor start-up, especially in conveyors and pumps. The indicating version speeds fault location, shortening maintenance windows. Combined with robust protection and long service life, this results in lower maintenance costs, fewer damaged downstream components, and a faster return on investment for industrial protection schemes.
