Mersen TR175R - TR Series Fuse 175A (RK5 Class 250V)

Mersen TR175R is a low-voltage current-limiting fuse designed for comprehensive circuit protection in industrial power distribution systems. This 175A rated fuse provides reliable overcurrent protection with a 250V AC voltage rating and features a 200kA interrupting capacity at 250V for high-fault current applications. Constructed as a single-barrel RK5 class fuse with a 1.56-inch diameter, it employs time-delay characteristics to prevent nuisance tripping from motor starting currents and other temporary overloads. The TR175R meets industry standards for current-limiting fuses and is commonly deployed in motor branch circuits, feeder circuits, and industrial control panels where selective coordination and equipment protection are critical requirements.
