What is quenching an arc? - Standex Electronics

Quenching the arc refers to the stoppage of the arc and/or metal transfer. If you are having to break high voltages care must be advised to minimize the amount of current flowing at the time of contact opening to minimize the metal transfer. Minimizing the current will prolong the life of the contacts. ‹ What causes early switching failures?Get price
