The Metal Oxide Varistor or MOV is a voltage dependent, nonlinear device that provides excellent transient voltage suppression. The Metal Oxide Varistor is designed to protect various types of electronic devices and semiconductor elements from switching and induced lightning surges.
What is a surge protector?
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.
What is the difference between a power strip and a surge protector?
A surge protector will also protect your electronic devices from a power spike. In order to tell the difference between a power strip and a surge protector, you have to look for an electric rating. A surge protector will have a rating in Joules of energy, as well as the maximum voltage it can take from a power spike.
