Metal Oxide Varistor (MOV)

### SELECTING THE PROPER MOV VOLTAGE RATING:

1. Determine the required voltage rating.
First, the maximum steady-state operating voltage of the circuit must be determined. Care must be taken to use the upper tolerance limit of the voltage source, e.g., for a 220VAC line,a 10% high line condition should be assumed, resulting in 242 Volts. Once the level is determined, refer to the column in the data table headed "Maximum Continuous Voltage" and select a group having the nearest greater value to this level.
