Cutler Hammer TR1-1/8R - Class RK5 Fuse 1A 250V (200kA AIC)

The Cutler Hammer TR1-1/8R is a Class RK5 low-voltage current-limiting fuse from the Tri-Onic family, engineered to provide reliable overcurrent protection for industrial electrical circuits. It features a 1A current rating and a 250V AC voltage rating, with an impressive 200,000A interrupting capacity at its rated voltage to safely clear high-level faults. The fuse is constructed as a single-barrel unit with a compact 0.56-inch diameter and a robust design that ensures stable performance. It complies with industry standards for RK5 class fuses, offering time-delay characteristics to prevent nuisance blowing from motor starting currents. This fuse is typically applied in the protection of motor circuits, transformers, and other electrical equipment where high interrupting capacity and time-delay features are required.
