FAQ
Microbreak module overtemperature alarm or overtemperature power off protection

a、Check whether the load current actually passed by the micro-break is too large, and whether the coefficient of the rated value and the actual value exceeds the normal configuration redundancy; 

b、Please contact the supplier.

The switch module does not work when the switch is controlled remotely

In this case, the device may be disconnected from the network. Check whether the power box is effectively connected to the Internet.

After installation and power-on, the main circuit will trip out immediately after closing
Instantaneous trip trip is generally caused by excessive line leakage, line short circuit (line misconnection will also cause leakage protection), need to re-check the line before the above situation can be closed.
After the device is installed, the status indicators are off

a. Check whether the 220VAC input of the P25 power module is properly connected and supplies power.

b. Check whether the 6-pin pins between switch modules are properly connected, and troubleshoot problems such as pins not inserted, position deviation, deformation, and short circuit.

After the first installation and power-on, the main circuit will normally trip after closing

a, because the line current exceeds the limit of overcurrent protective tripping, check whether the actual total current of the measured main circuit or branch output exceeds the switch rating or the pre-set power limit;

b, the use of leakage protection microbreak equipment, the actual leakage value of the equipment or line is unstable, when the leakage current exceeds the limit threshold cause leakage protection trip; 

c, because the input voltage is too high and protective tripping, check whether the actual voltage of the measured main input port exceeds the product threshold (single-phase 263V, three-phase 456V).

The device displays online but cannot effectively control the switch module (the UART light of the module is not on or blinking for a long time).

aCheck whether the address of the smart microbreak module used in matching has been set (the address can be set manually), whether the setting is correct (to avoid duplicate addresses), and whether the 6PIN pin connection has short circuit, open circuit and other problems; 

bAfter confirming that the communication and address are normal, try to restart the communication module and observe whether it is restored; 

c, communication failure, please contact the supplier.

After the first installation and power-on, when the main circuit or branch is closed by manual operation of the push rod, the push-rod clamp will not move

The ON/OFF key on the module can be switched on and off, and the electric control can be restarted after several times.

After the first installation and power-on, the shunt will normally trip after closing

The branch will automatically protect the line current limit, and check whether the actual total current of the measured branch output exceeds the nominal value of the branch or the preset power limit.
