Industrial LPJ-100SP Fuse

The LPJ-100SP is a 100 A, Low-Peak Class J fuse from Eaton’s Bussmann LPJ series, designed for protection of circuits up to 600 VAC or 300 VDC. This time-delay, dual-element current-limiting device delivers fast response to overcurrents while tolerating brief inrush events, with an interrupting rating of 300 kA at 600 VAC and 100 kA at 300 VDC. The fuse is non-indicating and UL listed, CSA certified, and features a bolt-on body for secure installation in panels or switchgear. Its physical form is about 4.625 inches long and 1.109 inches in diameter, weighing roughly 0.3 lb. The LPJ-100SP is designed to coordinate with upstream LPJ devices in protection schemes, helping achieve selective protection in multi-fuse circuits. Common applications include industrial control panels and power distribution circuits requiring Class J protection with high-voltage ratings.
