Cutler Hammer TR2-1/4R - TR Fuse 2A (Class RK5, 200kA AIC)

The Cutler Hammer TR2-1/4R is a Class RK5 time-delay fuse from the Tri-Onic family, engineered to provide reliable circuit protection for motor circuits and transformers by handling temporary inrush currents without nuisance opening. It features a 250V AC voltage rating and a 2A current 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 device with a compact 0.56-inch diameter and a lightweight design of 0.05 lb for straightforward integration into compatible fuse holders. This fuse is built to meet industry standards for low-voltage protection applications, ensuring consistent performance in demanding environments. It is typically applied in industrial control panels, motor starter circuits, and transformer protection where durable, time-delay overcurrent protection is required.
