The AOUE1+2 line is a group of Class I+II Surge Protective Devices. They are intended as a protecti-on against indirect and low intensity direct hits of lightning strokes. In standard three phase TN-C grid, they provides protection to LPL III, IV requirements given in EN 62305 with total lightning current introduced into electrical installation of 37.5 kAand totallightning stroke current 75 or 100kA based on physical conguration and mutual position of grounding point of lightning rod, grounding point of the electrical installation and place of SPD installation.
