TR110R - 110 Amp Fuse

TR110R - 110 Amp Fuse

The TR110R Class R Fuse is made for your electrical systems that take a beating every day. Rated for 110 amps, this time-delay fuse helps protect equipment from overloads and short circuits without opening during normal startup surges. That’s especially important for motors, compressors, and other equipment that naturally pull extra current when powering on. Its current-limiting design helps cut fault current fast, which can help reduce damage to connected equipment if a short circuit happens. In busy industrial or commercial environments, that extra layer of protection can make a real difference in keeping systems running and avoiding unnecessary downtime. The knife-blade style construction allows for a solid fit in compatible Class R fuse holders, making it a practical choice for maintenance teams, electricians, and facility operators who need dependable overcurrent protection.
