103335 Surge Protective Device Ex9UE1+2 12.5R 1PN 275

EAN: 8592765033369

The Ex9UE1+2 12.5 line is a group of Class I+II Surge Protective Devices. They are intended as a protection 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 kA and total lightning stroke current 75 or 100 kA based on physical confi guration and mutual position of grounding point of lightning rod, grounding point of the electrical installation and place of SPD installation. The design of Ex9UE1+2 12.5 is based on high energy Metal Oxide Varistors. Such design provides low response time and ensures characteristics for both classes I and II. The modular design with plug in inserts allows simple and quick replacement of function modules in case of MOV is beyond if its lifespan due to high intensity or often occurrence of overvoltage peaks.
