Cutler Hammer TRS20R - Class RK5 Fuse 20A 600V (200kA AIC)

The Cutler Hammer TRS20R is a Class RK5 low-voltage current-limiting fuse designed to provide reliable circuit protection in industrial power distribution systems. This 600V AC-rated fuse features a 20A current rating with a 200kA interrupting capacity at 600V, ensuring robust short-circuit protection. Constructed as a single-barrel design with a 0.56-inch diameter, the TRS20R utilizes time-delay characteristics to prevent nuisance tripping from motor starting currents and other temporary overloads. It complies with industry standards for RK5 class fuses, providing coordinated protection with upstream devices. Typical applications include motor branch circuits, transformer protection, and feeder circuits in industrial facilities and commercial buildings where selective coordination is required.
