Overview
The Gould Shawmut Ferraz Trionic TR10R time-delay fuse is a Class RK5 current-limiting cartridge fuse engineered for overcurrent protection in motor and transformer circuits. This lot includes 4 individual TR10R fuses rated at 10 amperes and 250VAC/160VDC, each measuring 2 inches in length with a 9/16-inch diameter ferrule terminal. The TR10R fuse features time-delay characteristics that safely accommodate harmless inrush currents typical of motor starting and transformer energization, making it ideal for branch circuits, feeders, and service entrance equipment.
