Selecting a Class J fuse holder
Pick the holder by the fuse ampere rating first, because Class J fuse bodies change size at 30, 60, 100, 200, 400 and 600 A and the clips only fit one size. Then match the wire range to the conductor you are landing and check the terminal torque. An enclosed DIN rail holder keeps fingers off live parts in a control panel. An open reinforced holder is the low cost choice inside a bolted enclosure. Send the fuse size, wire size and pole count and we will pick the catalog number with you.
