Cooper Bussmann LPJ-60SPI 60A Class J Time Delay Fuse

Product Description

The COOPER BUSSMANN LPJ-60SPI is a Class J time delay cartridge fuse rated at 60 amps for use in industrial and commercial electrical systems. It features a dual-element design that tolerates temporary inrush currents while still providing fast, reliable overcurrent protection under fault conditions. The fuse body measures 27 mm in diameter and 60.30 mm in length, fitting standard Class J fuse holders. At 0.18 pounds, it is a compact component with a high interrupting rating of 100 kA at DC and 300 kA at AC (RMS), making it suitable for demanding service environments where high available fault current is a concern.

This fuse is used in panel boards, motor control centers, and other Class J fuse holder applications in residential, commercial, and industrial settings. The indicating feature signals when the fuse has opened, helping electricians quickly identify a blown fuse during troubleshooting without removing it from the holder. Its general-purpose classification makes it a common choice for branch circuit and feeder protection in a wide range of electrical distribution equipment.
