Question 224Electricity & Electronics - Assistant Engineer

The correct answer is A) low voltage protection. The low voltage protection circuit is designed to prevent automatic restarting of the motor after a power failure. This type of circuit will not allow the motor to restart automatically once power is restored, as it is intended to protect the system from potentially dangerous or damaging conditions that could arise from an uncontrolled restart. The other options are incorrect because: B) overload lockout refers to a circuit that prevents the motor from restarting after an overload condition, C) reduced voltage restart allows the motor to restart at a lower voltage, and D) low voltage release is a circuit that disconnects the motor from the power source when the voltage drops below a certain level.
