A common misconception is that fuses and circuit breakers protect the motor from overheating. Alerich emphasizes that fuses protect the circuit wiring from short circuits, while protect the motor from drawing sustained excess current. Thermal Overload Relays
Step-down transformers that reduce high line voltage (e.g., 480V) to a safer control voltage (e.g., 120V) for the control panel components. 4. Advanced Control Methodologies
