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

Cutler Hammer TR1/10R is a low voltage current-limiting fuse designed for providing reliable overcurrent protection in industrial electrical systems. This 1A, 250V AC fuse features a 200kA interrupting rating at 250V and carries a Class RK5 rating, ensuring superior short-circuit protection and compatibility with standard rejection-style fuse holders. Constructed as a single-barrel device with a 0.56-inch diameter, the Tri-Onic time-delay design helps prevent nuisance tripping from motor starting currents and other temporary overloads while maintaining a compact form factor. Engineered to meet industry standards for safety and performance, this fuse is commonly applied in motor branch circuits, transformer protection, and industrial control panels where coordinated protection schemes are required.
