operATion
In case of overcurrent, device thermal protection interrupts power supply to connected devices.
The thermal protection will interrupt only one conductor, the other one will be kept connected to the
respective input terminal pin.
To activate again the device, press the restore button; in case of short-circuit or overload, restart will not
be possible.
Turned on led indicates the presence of power supply voltage and active protection.
Turned off led indicates a protection intervention and this must be replaced (the load is kept powered, but
without protection).
Indicator led
Restore button
The led stays off also in case of mains failure.
