Starters in motor control primarily consist of

• A. A contactor and an overload protection device
• B. A timer and a fuse
• C. A switch and a resistor
• D. A diode and transformer

Answer: (A)

In motor control, a starter is built around a heavy-duty switch and protective device. The contactor acts as the main switch that carries the motor’s high current and is operated by a low-current control circuit, allowing safe remote start and stop. The overload protection device senses excessive current or overheating and opens the circuit to prevent damage to the motor windings. Together, they provide both reliable starting and essential protection, which is why this pairing is the standard starter arrangement. A timer and fuse lacks the necessary remote switching and proper motor protection; a switch paired with a resistor would waste energy and isn’t suitable for starting a motor; and a diode with a transformer serves different control functions, not the fundamental starter purpose.
