As shown in the illustration, what is the purpose of the Time Delay (TR) coil in the circuit? EL-0104

Correct Answer: Option B — Allows the motor to come up to speed at reduced voltage before bypassing the starting resistors.

The Time Delay (TR) coil functions as a timing relay in reduced-voltage starting circuits. It allows the motor to accelerate to a predetermined speed using starting resistors or autotransformers before the timer expires, at which point the controller bypasses the resistors to apply full line voltage for normal operation.
