A surge protector like this one manufactured by the reputable brand Mora is an appliance or device designed to protect electrical devices from voltage spikes as well as current 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.
