Final Answer :
True
Explanation :
The control circuit is an essential part of both the contactor unit and the overload unit. Both units work together to ensure that the motor is protected from overload and can perform its functions efficiently. The control circuit is responsible for activating the contactor and overload unit, and monitoring the motor's performance. Therefore, both units need to have the control circuit to function correctly.
