TR10R - 10 Amp Fuse

TR10R - 10 Amp Fuse

When your electrical systems experience motor-startup surges or temporary overload conditions, having the right fuse in place can make a real difference. The TR10R is a 10-amp Class R time-delay fuse built for applications that need dependable overcurrent protection without unnecessary interruptions. Its current-limiting design helps reduce the amount of fault energy that can flow through a circuit during a short circuit, protecting connected equipment and minimizing downtime. This cartridge-style fuse features a compact footprint, making it easier to fit into crowded panels, disconnects, and control equipment. The time-delay functionality is especially useful in circuits with motors, transformers, or other equipment that naturally draw a higher inrush current at startup. Instead of opening too quickly during those brief surges, the TR10R is designed to ride through normal temporary spikes while still responding to true fault conditions. With a 200 kA interrupting rating at 250VAC, it is suited for demanding commercial and industrial electrical systems where high available fault current is present.
