Semitec Zenamic MOVs

The Metal Oxide Varistor Zenamic has large surge current handling capabilities, allowing for the absorption of transient overvoltage in a compact size. Peak current surges of up to 6500A (8/20 s) and peak power surges of up to 565J (10/1000 s) respectively can be limited by these fast-acting devices.


  • Lower Clamping Voltage for better surge protection
  • Fast response to high speed transient/surge voltage
