Bussmann by Littelfuse LPJ-600SP Class J Fuse

LPJ-600SP is Eaton Bussmann's Class J low-peak, dual-element time-delay fuse rated for 600 A and 600 VAC (300 VDC). This non-indicating, bolt-on device uses bolted blade-end terminations and delivers a high interrupting rating of 300 kAIC at 600 VAC and 100 kAIC at 300 VDC, making it suitable for large-power feeders and motor-control circuits where short, high inrush currents must be tolerated without sacrificing protection. As a time-delay, dual-element current-limiting fuse, the LPJ-600SP provides reliable protection against sustained overcurrents while allowing brief surges, helping to minimize nuisance blows in equipment with inrush. The LPJ family, known for Class J protection, is designed for high-current applications in industrial power distribution, and the 600SP variant specifies a 600 A, 600 VAC/300 VDC rating with non-indicating operation, aligning with installations that require fast, dependable fault clearing without an indicator display.
