Air break switches are used to isolate high voltage electrical circuits. They are generally used in power distribution systems.They use air is the breaking medium. These witches are normally used for outdoor application and are supported on porcelain insulators. Arcing horns are used for quenching the arc from magnetizing currents. The switches may be of single (center break) or double break construction. The movement action may be rotating or tilting type. They are meant for isolation purpose only and not for interrupting currents flowing in live circuits. This page shows the catalog of companies which manufactures/markets the air break switches.
