Function

The 3RT1965-5AD31 changeover operating mechanism allows a single contactor to control two separate electrical circuits. When activated, it mechanically and electrically changes the state of the contactor, switching the load from one circuit to the other. This function is crucial for applications such as:

• Motor Reversing: Safely reversing the direction of a three-phase motor.
• Bypass Systems: Switching between a main power source and a backup or bypass circuit.
• Generator Transfer Switches: Automating the transfer of power from the grid to a generator during an outage.
