Question 321Electricity & Electronics - QMED

The correct answer is D) low voltage protection. The low voltage protection circuit is a safety feature that is designed to prevent the motor from starting or running if the voltage supplied to the circuit falls below a certain threshold. This is important to protect the motor from damage that can occur due to low voltage conditions, such as brownouts or power surges. The other answer choices are not correct because: A) Reduced voltage starting is a different type of motor control that gradually increases the voltage to the motor during startup to reduce the high inrush current. B) Low voltage release is a feature that shuts off power to the motor if the voltage drops too low, rather than preventing it from starting. C) Resistance starting is a method of reducing the starting current of a motor, but does not involve low voltage protection.
