The Eaton Cutler-Hammer GD3030N is a general-duty, 3-pole circuit breaker designed to protect 3-phase electrical circuits from overloads and short circuits. It is rated for 30 amperes at up to 480 volts, making it suitable for 3-phase commercial or industrial power distribution. Use it in panelboards or distribution setups where a GD-series 30A, 480V, 3P protection device is required to safely interrupt fault currents.
