what are the function of the surge protector
to protect the electrical device from voltage flactuation
to protect electrical devices from voltage spikes
is the device designed to limit extra voltage
A surge protector (or surge suppressor or surge diverter) is an appliance or device designed to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or shorting to ground any unwanted voltages above a safe threshold.
