The varistor is used to protect the windings of electric motors from voltage peaks.
The varistor is applied where transient voltage peaks might damage the windings of electric AC motors.
The varistors are connected in parallel to the motor winding. They limit voltage peaks at the terminal of the motor winding.
- suitable for all multipolar motors in star or delta connection format
- compact housing for mounting in the motor terminal block
- very fast reaction time
- high energy consumption, good damping of transients
- optional polarity
