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

The Cutler Hammer TR1-1/4R is a Class RK5 low-voltage time-delay fuse designed to provide reliable circuit protection for motor circuits and other applications requiring withstand of temporary inrush currents. It features a 250V AC voltage rating and a 1A current rating, engineered to interrupt up to 200,000 amperes at its rated voltage. The fuse is constructed as a single-barrel device with a compact diameter of 0.56 inches and a lightweight design weighing 0.05 lb. This Tri-Onic series fuse complies with industry standards for current-limiting fuses, ensuring enhanced equipment protection. It is typically applied in industrial control panels, motor branch circuits, and transformer protection where a high degree of interrupting capacity and time-delay characteristics are required.
