The Ferraz Shawmut TRS10R fuse is a type of fuse that is used to protect electrical circuits from overcurrent. It is a time-delay fuse, which means that it is designed to allow a temporary overcurrent condition to exist before it opens (breaks the circuit). This feature helps to prevent nuisance tripping and allows for the proper operation of certain types of equipment. The TRS10R fuse has a current rating of 10 amps and a voltage rating of 600 volts. It is typically used in industrial and commercial applications.
