    摘要: Switching contacts of a switching device are provided to ensure optimum service life. An optimum switching point, in terms of the load of one of the switching contacts, is determined depending on a current path that is measured during the switching process and the switching point is shifted by a delay time from switching operation to switching operation. The optimal switching point is preferably determined by self-calibration of the switching device.

    摘要: A switching device in which destructive stress on the contact carrier when short-circuit forces occur when ON is prevented. Stops on the arcing chamber limit the opening movement of the contact bridge before the contact spring is compressed to its block dimension.
