A manual motor starter is an electromechanical device used to manually control and protect electric motors. Its main functions include:
1. Switching: It allows the manual switching of the motor on and off.
2. Overload Protection: It protects the motor from damage due to overload conditions by automatically cutting off the power when the current exceeds a preset level.
3. Short Circuit Protection: Some manual motor starters include protection against short circuits, though this is often provided by separate fuses or circuit breakers.
4. Phase Loss Protection: In some cases, manual motor starters can protect against phase loss in three-phase systems, preventing the motor from operating under potentially harmful conditions.
