Cutler Hammer TR1-8/10R - TR Fuse 1A (200kA AIC, RK5 Class)

The Cutler Hammer TR1-8/10R is a low voltage current-limiting fuse from the Tri-Onic family, engineered to provide reliable circuit protection in industrial applications. 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 is built to the RK5 classification, offering a high degree of current limitation and energy let-through control. This design complies with industry standards for time-delay characteristics, allowing it to withstand harmless transient overloads while providing fast response to short-circuit faults. It is typically applied in the protection of motor circuits, transformers, and feeder circuits where a high degree of protection and coordination is required.
