The Fuse Switch Is Tripped And Cannot Be Pushed Up

There are many possible reasons why Isolator switch trips and cannot be pushed up. Here are some troubleshooting steps and solutions:

1. Possible reasons‌

Circuit overload‌: When the current in the circuit exceeds the rated current of the fuse switch, the switch will automatically trip to prevent overheating and fire. This is usually because too many high-power electrical appliances are used at the same time‌.
Short circuit‌: Direct contact between the phase line and the neutral line or ground line in the circuit will cause a short circuit, causing the switch to trip. Short circuits may be caused by aging wires, damaged insulation, or internal electrical failures‌.
Leakage‌: Electrical equipment failure, aging lines, etc. may cause leakage, and the fuse switch trips to protect the circuit. When there is leakage, the reset button of the leakage protection switch usually pops out‌.
Fuse switch failure‌: The internal contacts of the switch are aging, poorly contacted or damaged, and cannot be closed normally, which will also cause tripping and failure to push up‌.

2. Troubleshooting steps‌

Disconnect all electrical appliances‌: First turn off all electrical appliances, including lamps and devices on sockets, to reduce the circuit load‌.
Try to reset the switch: Check if the reset button of the fuse switch or leakage protection switch pops up. If it pops up, press the reset button and try to push the switch again.
Check the appliances one by one: If you still cannot push the switch after resetting, you can plug in the appliances one by one, and try the switch each time to determine which appliance caused the trip.
Check the circuit problem: If the above steps cannot solve the problem, it may be a problem with the power line. At this time, you should disconnect the power line and try to push the switch again. If all appliances can be pushed up normally, it means that there is no problem with the appliances, and the problem lies in the power line, which requires professional inspection.

3. Precautions

When troubleshooting and solving problems, do not force the fuse switch to avoid the risk of electric shock.
If you are not sure where the problem is or cannot solve it yourself, it is recommended to contact a professional electrician for inspection and repair to ensure safe use of electricity.

Through the above steps, you can usually find out the reason why the fuse switch trips and cannot be pushed up, and take corresponding solutions.
