Are all surge suppressors created equal?
No. While the same suppression component, known as Metal Oxide Varistor (MOV), is used in most surge suppressors as the primary clamping component, the supporting circuitry, circuit board design, wiring techniques, and product features can result in product qualities that range from highly effective to ineffective and dangerous. While not always true, generally “you get what you pay for.” If you are purchasing from a reputable source you will generally have a selection of high, medium and lower quality devices. Nevertheless, the cheaper devices are made that way by sacrificing either protective or safety features.
