Bussmann LPJ-2-1 Dual Element Time Delay Fuse

The Bussmann LPJ-2-1 is a two-pole, Low-Peak LPJ dual-element time-delay fuse designed for Class J protection in electrical power systems. As part of the Bussmann LPJ family, it combines dual-element construction with current-limiting, time-delayed performance to tolerate brief inrush currents while delivering fast clearance during faults. It is rated for up to 600 VAC and 300 VDC, with a high interrupting capacity (up to 300 kA at 600 VAC and 100 kA at 300 VDC), and is offered as a non-indicating fuse in a 2-pole configuration (LPJ-2SP). Typical applications include protecting power distribution panels, motor drives, and other equipment with significant inrush currents where adherence to Class J protection and low-peak characteristics are important. The LPJ line is documented in Eaton Bussmann product catalogs and listings, including LPJ-2SP references and related dual-element, time-delay data.
