A metal oxide arrester (MOA) is an electrical device that is designed to protect electrical systems and equipment from surges caused by lightning, switching operations, and other sources of overvoltage. The MOA technology utilizes a metal oxide varistor (MOV) element that provides low impedance paths for high voltage surges, thereby diverting the excess energy to the ground.
