Starting winding of a single phase motor of a refrigerator is disconnected from the circuit by means of a___________?
Correct answer: A. magnetic relay
- A. magnetic relay
- B. thermal relay
- C. centrifugal switch
- D. none of the above
Explanation
Domestic refrigerator compressors commonly use a magnetic current relay to disconnect the starting winding after the motor accelerates. A centrifugal switch is generally unsuitable because the compressor motor is enclosed and has no accessible shaft mechanism.
