# # Industrial Reversing Starter Power and Control Schematic
This technical diagram, identified as **3394.png**, illustrates the **force and control circuits** for a reversing 3-phase motor. The "Circuito de Força" uses contactors **K1 and K2** to swap line phases, while the control logic incorporates an **emergency stop (EM)** and electrical interlocking. This setup ensures safe directional changes and thermal overload protection via **RT 1** for industrial motor applications.
