Abstract (en)
[origin: EP0140093A2] 1. Circuit arrangement for the direct-current operation of contactors, in which arrangement the control voltage is applied to the exciter coil (11) of the contactor (4) via a contactless electronic switching stage (12, 13), characterized in that the control line to the electronic switching stage (12, 13) can be short-circuited by means of a thyristor (17), the thyristor (17) being triggered via a sealed switching contact (16) which can be switched by the magnetic field of the current in the load circuit.
