<p>The device according to the invention includes parts of the traditional assembly of combined fuses like a specified handle for disconnecting the fuse switch, a fuse switch axis, a coil for electromagnetic disconnecting, an electromagnetic sliding circuit breaker, a standard contact mesh as well as part of a disconnecting spring. These parts are by their dimension preferably depending on the additional integration of a varistor and are therefore generally slightly narrower. The device according to the invention also includes a surge arrestor for direct lightning surges with preferably power gas self-extinguishable arrestor, which generally includes an earthing sheath, a metal enclosure, an external contact for faster ignition, a transformer for high ignition voltage which transforms the quickly rising impulse on the additional internal electrode of the gas arrestor, ignition small gas arrestor and ignition varistor.</p> |
