An "air break switch' is a switching device that uses air as the dielectric. Air Break Switches (ABS) are widely installed throughout distribution networks for use as both isolation or switching points.
They are usually employed in out door installations. Special Arcing Horns are provided to quench the arc which occurs when the current is interrupted. These switches are usually operated by a handle which is located at the ground level. Their operation can also be mechanised.
