How does the automatic recovery function operate?

The device continuously monitors circuit voltage. If the voltage exceeds the configured threshold, the load disconnects. When voltage normalizes within the set range, the load reconnects automatically.

Which types of conductors are supported for connection?

The device can be connected using both copper and aluminum wires.
