The Cutler Hammer TR4/10R is a Class RK5 low-voltage current-limiting fuse from the Tri-Onic family, engineered to provide reliable overcurrent and short-circuit protection for industrial electrical systems. It features a 4A current rating and a 250V AC voltage rating, with an impressive 200kA interrupting capacity at 250V to safely clear high-level faults. The fuse is constructed as a single-barrel unit with a 0.56-inch diameter and is built to meet industry standards for current-limiting protection. This compliance ensures enhanced system safety by significantly reducing let-through current and energy during fault conditions. Typical applications include the protection of motor circuits, transformers, and feeder circuits in industrial control panels and power distribution equipment.
