Why does the leakage circuit breaker trip when it heats up?

Heating means overload, so it will trip. Of course, this is also a kind of protection measure for electricity consumption by circuit breakers. Therefore, it is best to choose the circuit breaker on demand, too small and always tripping, too big.

It will not be protective. Hope it helps!

In two cases, the first may be a fever caused by overload. The second wiring screw is not compressed.

Summary. Hello dear, the leakage is always the cause of fever tripping is 1After tripping, first remove the power cord of the air conditioner from the leakage protection switch, test the power supply voltage of the input leakage protection switch, if it is normal, close the reset switch, and still trip in the case of no load, it is the internal fault of the leakage protection switch, if it does not look at the switch, it is a problem with the electrical appliance.

2.The leakage protection switch is overloaded due to small switching capacity, unconnected wires, overloaded electrical appliances, and high ambient temperature. 3.

The principle of replacing the leakage protection switch after the fault is not less than the original parameter, and the leakage current cannot be greater than the original parameter. 4.The fastening screws of the secondary lead-out line of the zero sequence transformer are loose or desoldered.

Changing a big leakage protection is not okay for a few days.

Yes, you can change it to a big leakage.

I see.

Summary. Hello dear, it is a pleasure to serve you! Improper installation may be caused by the leakage protector not being installed properly.

If the leakage protector is installed and the terminal post position is not firmly connected, then the wiring position of the pile head will be loosened, and after a long time, the terminal post position will appear heated, oxidized and other phenomena, resulting in the wire sheath being burned out, making the line undervoltage, resulting in the leakage protector always tripping. Thank you!

Dear, it's a pleasure to serve you. There are four reasons for the skip-shift rental type bucket gate: The leakage protector at home is poorly installed.

The quality of the leakage protection line is not up to standard. Improper operation by yourself. The leakage protector does not match the load.

The solutions are as follows: If the terminal posts of the leakage protector are not firmly connected during installation, it will cause the binding posts to heat up and oxidize for a long time.

Leakage protector tripping may be caused by defects in the leakage protector design, excessive ambient temperature, short circuit or open circuit, etc. 1. Design defects of leakage protector: leakage protector is a device for detecting voltage, which is installed in the circuit to detect whether the voltage exceeds the set safety range, and if it exceeds, the current in the circuit will be tripped.

If the design of the leakage protector is flawed, it will trip when the leakage protector detects that the voltage is outside the safe range. 2. The ambient temperature is too high: Since the leakage protector is an electrical equipment, its internal circuits and components will be affected by the ambient temperature.

If the ambient temperature is too high, it will cause the leakage protector to trip, which is blind because the voltage in the circuit may change, resulting in the leakage protector tripping. 3. Short circuit or open circuit: A short circuit in a wire may be caused by the damage to the wire itself, when the wire is broken or short-circuited, the voltage in the circuit will change, which may cause the leakage protector to trip.

What is the reason for the overheating of the leakage protector, check the cause first, and deal with it, there are generally the following reasons, one. The place where the line is connected with a virtual connection (that is, poor contact). Second, there is a problem with the leakage protector, and third, the electrical appliance is caused by too much load.

Check whether there is leakage, first rule out leakage, if there is no leakage, it may be that the protector has been used for a long time, aging is not good, just replace it with a new one.

Overheating is generally overloaded, check if there is a short circuit.

Due to the special nature of the design, the leakage circuit breaker can detect the presence of leakage in electrical equipment or circuits. When there is leakage in electrical equipment or circuits, the leakage circuit breaker will cut off the circuit in time to prevent potential safety hazards caused by leakage.

When the leakage circuit breaker heats up, it is mainly because the current exceeds the rated value, which causes excessive heat to be generated by the internal components of the circuit breaker. In this case, if the heating process lasts for too long, it will cause overheating and damage to the residual current circuit breaker.

When the temperature of the leakage circuit breaker exceeds the rated temperature, the thermal protection device may be triggered, at which point the leakage hail circuit breaker will automatically disconnect the circuit to protect the safety of the circuit and its equipment.

Therefore, the reason why the PIRC trips after heating up may be because the current in the circuit exceeds the rated value, resulting in excessive heating of the internal components of the PICB, which reaches the trigger temperature of the thermal protection device, thus triggering the trip protection measures.

If the leakage circuit breaker often has the problem of heating and tripping the brake, it is recommended to find the cause of the problem, which may be a short circuit or other fault in the electrical equipment or circuit, which needs to be repaired or replaced.

Summary. Hello, I'm glad to reply to you, the reasons why the leakage switch occasionally trips: 1. Caused by improper installation, due to the loose problem of the pile head lead, it should be connected firmly; 2. If the line voltage is too high, you can use a multimeter to check it, otherwise it is easy to cause a disaster; 3. If the wire is caused by moisture, the drying measures of the wire should be done.

4. If a certain load is exceeded, these situations will lead to exceeding the allowable safety current of the leakage protector, which is naturally prone to tripping. As soon as it is delivered, it will continue to trip, and it will not be delivered at all. There are also some leakage switches that do not meet the size of the specifications, because the wiring is loose, resulting in poor contact, which can also lead to direct tripping.

Choose leakage switch, if it is some inferior products, the materials and materials are not standardized, the insulation treatment at the wiring is improper, or the insulation level of the wire is not up to standard. I hope it will be helpful to you, and you can always find the teacher if you have any other questions in the future. I wish you all the best in your life.

The leakage switch needs to be turned down and re-plugged to restore power.

That's when the current is too high.

Do you use a lot of electrical appliances?

OK. Are there any traces of burning?

The air conditioner doesn't jump often in summer, and now it jumps if the air conditioner is not turned on.

There are too many lines and too complicated to check them all.

It must be inspected, and it is easy to have an accident if it is not checked.

It is recommended to contact an electrician to check it out for you.

Generally, a short circuit will jump down, but now it doesn't jump, the power goes out, and then it just hits down and hits again.

Mine, like you, jumped once in a while, and as a result, burned 6 later.

You ask an electrician to troubleshoot the problem for you.

What to burn? Burn it to boil.

My main gate and leakage are burning.

Until now, the cause has not been found.

It is to replace the use of higher current.

For example, if your maximum light current is 50A, but if you have 70 at home, it will basically not fall off for the time being, but it will burn and trip for a long time.

If the current is too large in an instant, it will jump, and then you can push it up after a while.

I always asked the electrician to come to the door.
