Cutler Hammer TR1-4/10R - TR Fuse 1A 250V (RK5 Class, 200kA AIC)

The Cutler Hammer TR1-4/10R is a low-voltage current-limiting fuse from the Tri-Onic family, engineered to provide reliable overcurrent and short-circuit protection for electrical circuits. It features a 1A current rating and a 250V AC voltage rating, with a high 200kA interrupting capacity at its rated voltage to safely clear severe fault conditions. The fuse is constructed as a single-barrel unit with a 0.56-inch diameter and a Class RK5 rating, which offers a high degree of current limitation and time-delay characteristics. This component is designed for use in industrial control panels, motor branch circuits, and feeder circuits where robust circuit protection is required.
