- This energy gets lost unexploited; also the motor is exposed to hig-her thermal stress
- Other thermal protection devices fail to detect continuing unbalances which can lead to damage or destruction of the motor
- The CM range three-phase monitors with phase unbalance monito-ring can reliably detect this critical situation
- Phase sequence Changing the phase sequence during operation or a wrong phase sequence prior to startup causes a change of the rotational direction of the connected device
