Smart plugs with surge protection

 

— a protective system that protects the load connected to the smart socket from voltage fluctuations in the network. Usually, relatively small and short-term power surges are extinguished by the outlet itself; if the protection capabilities are not enough, the power is automatically turned off, protecting the load from damage. Such protection is especially important for sensitive electrical appliances such as televisions or audio equipment; it will not be able to replace a full-fledged voltage regulator, however, for more or less stable networks in which fluctuations rarely occur, it is usually quite enough.
