Patent ID: 8863539

Claim:
A control apparatus configured to control a refrigerating apparatus including a compressor and a first circuit breaker, the first circuit breaker configured to interrupt a current flowing through the compressor when the current becomes greater than a predetermined current and configured to be closed in response to an operation by a user, the current flowing from a power supply through the compressor to cause the compressor to work, the control apparatus comprising: a voltage measuring unit configured to measure a voltage of the power supply; and a control unit configured to trip a second circuit breaker disposed in series with the first circuit breaker so that the current from the power supply flowing through the compressor is interrupted, when the measured voltage of the power supply becomes lower than a predetermined voltage, and close the second circuit breaker after the voltage of the power supply becomes higher than the predetermined voltage, the predetermined current corresponding to a current greater than the current flowing through the compressor when the voltage of the power supply is equal to the predetermined voltage.
