Surge protectors contain a small disc called an MOV (metal oxide varistor). MOVs don't clamp down when there is a sustained electrical overload, only for anomalies like spikes. Though MOVs can ...

The most common method is the use of a metal oxide varistor (MOV), which acts like a pressure relief valve to divert the surge to neutral and/or ground. However, shunt mode methods can be problematic.

Surge protection is another key feature, with the strip's 3-level protection circuit composed of a transient voltage suppressor (TVS), metal oxide varistor (MOV), and gas discharge tube (GDT ...
