Feature → Business Impact → Application: Time-delay, dual-element design provides controlled response to inrush, reducing nuisance tripping and improving overall equipment uptime in pump and conveyor circuits. This leads to lower maintenance costs and higher line availability in manufacturing lines. Application: ideal for motor-driven loads in automation panels where start-up surges can trip fast fuses, yet reliable protection is essential for motors and drives.

FAQs
To install LPJ-12SP, ensure the panel is de-energized and space the ferrule ends to fit standard bus bars or fuse clips. Verify the ferrule-end x ferrule-end configuration, align with the circuit protection scheme, and secure with appropriate clamps. Check that the 2.25 in length fits your enclosure depth and that wiring gauge adheres to the 12 A rating for safe operation.
LPJ-12SP is a 12 A Class J time-delay fuse with dual-element current-limiting. It is rated for 600 VAC and 300 VDC, with a 300 kAIC interrupt rating at 600 VAC and 100 kAIC at 300 VDC. The response time is 10 seconds at 500% overload, providing protection for motors while tolerating inrush; connections are ferrule-end x ferrule-end.
Yes. The LPJ-12SP combines time-delay behavior with current-limiting dual elements, allowing it to endure motor start-up surges while limiting damage from short-circuit faults. This makes it well-suited for motor drives, conveyors, and other equipment with brief inrush spikes, reducing unnecessary shutdowns without compromising safety.
LPJ-12SP is CE marked and RoHS compliant, ensuring conformity with European regulatory requirements and electronics recycling standards. This combination supports global deployment in industrial automation projects and helps meet procurement standards for regulated environments.
The LPJ-12SP’s dual-element design reduces nuisance trips, lowering unplanned downtime and maintenance costs. Its compact form factor and ferrule-end connections simplify installation and replacement in established fuse blocks, enabling predictable lifecycle costs and a quick return on investment through improved system reliability.
