What else can I help you with?
What are the possible cause that motor compressor trip?
there is a possibility that parts of motor windings has partial damage.
How does a thermal overload control a circuit when the phase short to ground?
If you are describing a circuit breaker then its electromagnetic trip component will operate in the event of a line*-to-ground (*not 'phase'!) short circuit. The thermal overload component will only operate in the event of a sustained overload.
What would cause a circuit breaker heating element to trip off?
There are two conditions that would cause a breaker to trip off. One is an overload of the circuit and the other is a short circuit on the circuit. The heating element within the breaker is what monitors for circuit overloads.
What is transient overload?
Sustained overload is overload that is continuous, or permanent. A resistive load is a good example. This is the kind of overload you get from simply plugging too many items into a circuit. Transient overload is overload generated by a reactive load, a momentary short circuit, or other temporary condition. An example of a reactive load is the compressor of an air conditioner starting. This kind of overload can be caused by a reactive load being added to an already moderately loaded circuit.
If a suction side valve is damaged what will happen?
You will lose capacity and efficiency. The compressor may also run HOT and cycle on its internal overload protection device.
What will cause a star delta panel to trip in delta?
On a star delta starter a motor overload or a motor going to ground and cause a short circuit will cause the overload protection to trip. These overloads have to be reset before the motor can be restarted.
What terminal in a hermetic compressor is the internal overload located?
In a hermetic compressor, the internal overload protector is typically located on the compressor's start winding terminal. This overload device is designed to interrupt the electrical current if the compressor overheats, helping to prevent damage from excessive temperature. It ensures the compressor operates safely and efficiently.
Can a breaker be bad and not trip when there is an electrical overload?
Yes, a breaker can be faulty and fail to trip when there is an electrical overload.
The compressor overload should be set at at how many amps?
The compressor overload should generally be set to trip at around 10-15% above the rated running amps of the compressor motor. This helps protect the compressor from overheating and potential damage during prolonged overcurrent conditions. It is recommended to refer to the manufacturer's specifications for the exact amp rating.
What is the purpose of the internal overload protector in the compressor motor?
No
What are the possible cause that motor compressor trip?
there is a possibility that parts of motor windings has partial damage.
What happens if a compressor is shorted to ground?
If a compressor is shorted to ground, it can cause an electrical overload and potentially damage the compressor or other components in the system. This can lead to the compressor not functioning properly or failing altogether. It is important to address any electrical issues promptly to prevent further damage to the system.
Why does the compressor keep turning off in your air conditioner?
More than likely it's the internal overload on the compressor kicking it out.
Why is there a delay in restarting a compressor that has kicked off due to an overload?
Sequencer is out of sequence
Why is there a delay in a compressor that has kicked off due to an internal overload?
Sequencer is out of sequence
Why does a circuit breaker trip?
A circuit breaker trips when there is an overload of electrical current flowing through the circuit, which can cause overheating and potentially start a fire.
What is wrong if your AC blows cool for about a minute and then the outside shuts off and the fan just blows hot air?
It could be any one of the following: 1. The fan motor is overheating and is shutting down on overload, which will cause the compressor to shut down via the high pressure switch. 2. The compressor is getting too hot and is shutting down via the thermal overload switch. You need to determine if the fan and the compressor both come on at the outdoor unit. If you are getting cold air inside the house, the compressor is probably running. It generally takes longer than 1 minute for the fan to go out on overload unless the bearings are shot, then the fan motor could seize up and shut the compressor down on overload. You should have this checked by an HVAC tech.
