Abstract (en)
Circuit arrangement has an output contact (D), which is connected to the integrating circuit (TR1,R2,R3,C3,TR2) and time-dependently suppresses a turn-on current surge at the output contact. The output contact is further connected to the discharge circuit (R4,R5,R6,R7,KOMP1), which discharges the output contact during the undershoot of the cut-off voltage at the output contact.
