Causes of circuit breaker tripping caused by air conditioning


1. The fuse in the air-conditioning special circuit is blown, or the power switch is in poor contact, or the power supply is missing phase. At present, many households only use one power supply, which may cause abnormal power supply due to abnormal operation of other appliances.

RCBO

2. The power supply used by the air conditioner is too low. When the voltage is lower than 10% of the 220V single-phase normal voltage, that is, 198v or less, the refrigeration compressor in the air conditioner is difficult to start up.


3, the dial knob on the temperature controller is not dialed to the appropriate position, such as dialing to a higher position, when the power is connected, the temperature in the air-conditioned room has not reached the upper limit of the set temperature, the compressor can not Start the run.

RCBO

4, high pressure relay action, such as condensing pressure is too high, so that the high pressure relay action, stop the compressor's operation.

RCCB

5, low-pressure relay action, such as the lack of refrigerant in the refrigeration system, resulting in the compressor suction pressure is too low, so that the low pressure relay action, stop the compressor's operation.


6. When the current of the compressor and fan motor is too large, the overload protection relay is operated to cut off the power supply.
