The growing influence and presence of microprocessor based equipment and devices have greatly increased the risk of damage or malfunction due to AC power and telecommunications line voltage surges and transients. These rapid increases in voltage can result from lighting strikes, power grid switching, large inductive loads (HVAC, motors, etc.), electrostatic discharge, and arcing from relays or switches.

Our MOV data sheets present our High Energy NS Series, as well as our Low Voltage ZM and ZR Series and our standard NR Series. Additionally, Voltage-Current MOV Characteristic Curves and complete technical and packaging specifications are available in our full catalog.
