Ahas no low voltage protection and the motor may be damaged if the voltage drops below a certain level

Bincorporates low voltage release because the motor will stop when voltage falls below a certain value and automatically start when normal voltage resumes

Cincorporates low voltage protection because the motor will stop when voltage falls below a certain value but must be manually restarted when normal voltage resumes

Dincorporates low voltage protection because the motor will stop when voltage falls below a certain value and automatically start when normal voltage resumes

AI Explanation

The correct answer is A) has no low voltage protection and the motor may be damaged if the voltage drops below a certain level. The illustrated manual starter circuit for a motor shown in figure "A" does not incorporate any low voltage protection. This means that if the voltage supplied to the motor drops below a certain threshold, the motor will continue to run without any automatic shutdown or protection. This could potentially damage the motor if the voltage drops too low for an extended period of time. The other answer choices describe circuits that have some form of low voltage protection, which is not the case for the manual starter circuit shown in figure "A".
