The PAN11 is a Plug-in Switch, which can be placed between a wall outlet for Schuko plug and electric devices with a resistive load up to 3000W, plugged in by cord. In addition, this intelligent plug-in switch is able to detect the voltage, measure the electric power taken by this load (in Wh) and meter the electrical energy consumed (in kWh) as well as detect a possible overload (3010 ~ 3300W) of the connected electrical device. When detecting an overload, the module is deactivated and the LED will flash for 30 seconds.
