FAQs
Yes. LPJ-90SPI uses bolted blade end x bolted blade end connections, designed for straightforward panel mounting and easy integration into standard Bussmann/Class J assemblies.
The fuse is rated for 90 A, 600 Vac (600 Volt AC) with an interrupt rating up to 300 kAIC, and it provides a 10 second response at 500% for startup transients, making it suitable for inrush-heavy motor loads.
It is recommended for motor drives, pumps, and conveyors in industrial environments where reliable inrush protection and current limiting are essential to minimize nuisance trips and protect downstream equipment.
The LPJ-90SPI is CE marked and RoHS compliant, ensuring global regulatory alignment for multinational deployments and helping with compliance reporting.
By reducing nuisance trips, providing robust motor protection, and enabling standardized installation, the LPJ-90SPI lowers downtime, extends motor life, and simplifies spare-part management across sites.
