Mersen/Ferraz Shawmut Fuse: 10 A, 600V AC, 2-1/4 in L x 13/16 in dia Fuse Size, Cylindrical Body

Time-delay, indicating UL Class J fuses tolerate temporary inrush currents without opening, which prevents nuisance-blowing from motor and equipment startups. Also called slow-blow Class J fuses, they open to disconnect an electrical circuit when exposed to sustained loads and short circuits. They have a visual indicator to make it easier to identify blown fuses for replacement.

UL Class J fuses have a high interrupting rating for protecting against short circuits and are ideal for IEC motor starter applications. These 600VAC fuses are not interchangeable with any other UL fuse class. They are current-limiting to prevent electrical damage by disconnecting circuits before they're exposed to the full magnitude and duration of an overcurrent.
