The Littelfuse Bussmann LPJ-45SP is a low-peak, Class J dual-element current-limiting fuse with a time-delay design. It is rated at 45 A and supports 600 VAC and 300 VDC, offering current-limiting protection with interrupting ratings up to 300 kA at 600 VAC and 100 kA at 300 VDC. This LPJ series fuse is meant for use in low-voltage circuits where brief surge currents occur, providing reliable short-circuit protection for power distribution and control applications that require fast-acting protection while tolerating inrush currents.
