Question 177Electricity & Electronics - 1st Asst/Chief

The correct answer is B) Allows the motor to come up to speed at reduced voltage before bypassing the starting resistors. The time delay (TR) coil in the circuit serves to delay the bypassing of the starting resistors until the motor has had a chance to come up to speed at a reduced voltage. This ensures a smooth, controlled acceleration of the motor rather than abruptly applying full voltage which could cause issues. The other answer choices are incorrect because they do not accurately describe the purpose of the TR coil in this type of motor control circuit.
