1. An actuation device, for actuating a circuit breaker, comprising:
a circuit arrangement and a plurality of resistor devices;
a plurality of first switching elements of the circuit arrangement are connected to a respectively assigned first voltage source and a respectively assigned resistor device and have a switching input that is connected to an actuation logic unit; and
wherein the actuation logic unit further comprises:
a superordinate actuation input and a plurality of sensor inputs;
wherein the actuation logic unit is designed to actuate the first switching elements in a clocked manner during the switching-on or the switching-off process of the circuit breaker;
wherein the respective first voltage sources have an identical voltage;
wherein the circuit arrangement has a second switching element that is connected to an assigned second voltage source and an assigned resistor device, and has a switching input; and
wherein the actuation logic unit is designed to actuate this second switching element in an unclocked manner during the switching-on or the switching-off process of the circuit breaker.
