Bussmann LPJ-400SP Low-Peak Fuse, Class J, 400 A, Dual, 600 V, Time Delay, 7.13 Inch Length

Description

Features

• Engineered with a robust 10-second time delay at 500% of its rated current, this Low-Peak fuse safely absorbs temporary inrush currents from heavy-duty machinery. This critical feature eliminates expensive nuisance tripping and facility downtime, ensuring seamless operation for large 600V industrial motors, transformers, and heavy manufacturing equipment.
• Boasting an industry-leading 300,000 Amp short circuit current rating (SCCR), this highly efficient current-limiting fuse stops massive fault currents in milliseconds. By significantly reducing thermal and magnetic forces during a high-fault event, it drastically lowers workplace arc-flash hazards, actively protecting your valuable downstream electrical panels, motor controllers, and personnel.
• Requiring up to 50% less mounting space than traditional Class R overcurrent devices, this compact cartridge fuse allows for significantly smaller, more cost-effective industrial panel designs. The specialized Class J footprint also physically prevents the dangerous accidental installation of lower-rated fuses, guaranteeing your commercial power distribution system maintains its exact safety rating.
• UL Listed and CSA Certified to handle rigorous continuous loads up to 400 Amps, this versatile Bussmann fuse provides absolute defense for both 600-volt alternating current and 300-volt direct current circuits. Trusting factory-tested, compliant hardware guarantees your facility effortlessly passes strict NEC electrical code inspections, delivering highly reliable protection for everything from variable frequency drives (VFDs) to main service disconnects.
