Description

technical field [0001] The invention relates to an electromechanical module according to claim 1 . Background technique [0002] So-called hybrid switching devices are known which have both mechanical switches and semiconductor switches. Such a switching device is known, for example, from WO 2015 / 028634 A1. Such switching devices differ considerably from purely mechanical switching devices, which in practice leads to completely different requirements on the electromechanical structure. [0003] In a hybrid switchgear, the deposition of current through the switchgear typically connects multiple mechanical contact pairs in series. This usually results in higher resistance and higher self-heating. At the same time, the power semiconductors are the central components that are crucial for switching off the current through the hybrid switching device. However, higher ambient temperatures shorten the service life of semiconductor switches. Failure of the semiconductor switch m...
