Feature → Business Impact → Application: Time-delay, dual-element design enables short-term overload tolerance without nuisance trips, improving uptime and reducing unplanned maintenance in motor drives and control circuits. Application: Ideal for motor protection in pumps, fans, and conveyors where inrush current is common and selective coordination is needed. Feature → Business Impact → Application: 7 A rating with 600 Vac and 300 kAIC interrupt capability provides strong fault protection with ample clearance for aggressive fault currents. Application: Suitable for industrial power distribution and machine control panels requiring high current interruption margins. Feature → Business Impact → Application: Dual-element current-limiting technology offers rapid fault interruption once thresholds are exceeded, reducing damage to downstream electronics and minimizing downtime in automation systems. Application: Fits control panels and motor starters where space is constrained but protection performance must not be compromised. Feature → Business Impact → Application: Ferrule end connections enable quick replacement and reliable bolting in standard electrical enclosures, improving install speed and field serviceability. Application: Retrofit or new installations in machine builders and panel shops. Feature → Business Impact → Application: Compliance with CE Marked and RoHS standards ensures regulatory alignment and easier supplier qualification for global projects. Application: Assemblies destined for European and RoHS-demanding deployments benefit from certified reliability. Feature → Business Impact → Application: Time-sense protection with low footprint reduces total installed cost and simplifies spare-part inventories. Application: Industrial automation cabinets and low-profile motor control centers.

FAQs
Yes. LPJ-7SPI uses ferrule end x ferrule end terminations, which are compatible with common control-panel bus bars and terminal blocks. Its compact dimensions (0.81 in by 0.81 in cross-section and 2.25 in height) fit tight panel spaces, while the dual-element design supports quick field replacement without extensive rewiring.
The LPJ-7SPI is rated 7 A with a 600 Vac maximum voltage and a 300 kAIC interrupt rating at 600 Vac (100 kAIC Vdc). These ratings provide strong short-circuit protection for motor loads and durable operation in high-current inrush conditions, ensuring downstream components are shielded while maintaining reliable starting sequences.
Yes. As a time-delay, dual-element current-limiting fuse, LPJ-7SPI accommodates moderate to high inrush currents typical of motor start-up. Its time-delay characteristic reduces nuisance trips, enabling smoother startup and longer motor life in conveyors, pumps, and fans without sacrificing protection.
LPJ-7SPI is CE Marked and RoHS Compliant, meeting essential European safety and environmental requirements. This supports regulatory acceptance in European markets and helps with supplier qualification on projects demanding RoHS and CE compliance for electrical protection devices.
The LPJ-7SPI offers reliable protection with reduced nuisance trips due to its time-delay feature, lowering unplanned downtime and maintenance costs. Its high interrupt rating and durable construction shorten service intervals, while easy ferrule-end replacement minimizes field labor and spare-parts inventory for OEMs and panel shops.
