This unit is designed as an inexpensive protection of sensitive electronic equipment against destructive overvoltage. It is directly in front of the device to be protected, or better, the distribution power strip, in which several devices are connected, integrated. Critical to the effectiveness, however, is that a protective conductor is connected to the socket used Regular shutdown of the connected devices but it should better not be used. Even a continuous load with the specified current rating I would not recommend, 2/3 should be enough. For particularly valuable devices I'd probably give a more perfect solution preference.
