Eaton Corporation Bussmann LPJ-70SPI Low-Peak Fuse

LPJ-70SPI is Eaton Bussmann series Low-Peak Class J dual-element, time-delay fuse with permanent fuse indication. This 70 A LPJ device uses blade-end terminations and fits standard LPJ fuse holders, measuring 4.63 inches in length, 1.13 inches in height, and 1.13 inches in width with a typical weight around 0.35 lb. It is rated for 600 V and carries an interrupt rating up to 300 kAIC at 600 VAC, making it suitable for protecting power distribution and equipment circuits from short-duration overloads. The SPI suffix denotes the indicating variant, which provides open-fuse indication (EasyID) and requires a minimum of 75 VAC to operate the indication circuitry; the indicating feature itself is not rated for DC. The fuse body is RoHS compliant and the part is UL Listed and CSA Certified for use in compliant systems. In practical terms, LPJ-70SPI offers reliable, time-delayed protection with a visible blown-fuse indication in industrial and commercial applications where rapid interruption of fault currents and straightforward fuse status monitoring are important.
