Question: Which of the following components is used in a motor control circuit to maintain the motor starter in the 'energized' state after the momentary 'start' button is released?
Answer options:
- Overload relay contacts ✅ Auxiliary contacts (NO) of the motor starter
- Stop button (NC)
- Selector switch
Correct answer: Auxiliary contacts (NO) of the motor starter
Explanation: Auxiliary normally open (NO) contacts of the motor starter are wired in parallel with the momentary start button to provide a 'seal-in' or 'holding' circuit, maintaining power to the coil once the main contactor pulls in. Overload contacts and stop buttons break the circuit, and a selector switch is for manual selection, not sealing-in.
