The Cutler Hammer TR3/10R is a Tri-Onic time-delay, current-limiting fuse designed to provide reliable branch circuit and feeder protection for motor circuits and transformers. It features a 3A current rating and a 250V AC voltage rating, with a high 200kA interrupting capacity at 250V to safely clear severe short circuits. The fuse is constructed as a single-barrel unit with a 0.56-inch diameter and is built to the RK5 classification, offering a dual-element design that provides both overload and short-circuit protection. This fuse complies with industry standards for low-voltage protection devices and is typically applied in industrial control panels, motor starter circuits, and transformer protection where sustained overloads and high fault currents are present.
