Abstract
A first voltage, which is dropped out onto a pull-down resistor that is coupled to a first power circuit breaker, is compared to an adjustable first reference voltage in order to determine a first comparative value. A second voltage, which is dropped out onto the pull-up resistor that is coupled to the second power circuit breaker, is compared to an adjustable second reference voltage in order to determine a second comparative value. Determination then occurs according to the first comparative value and second comparative value as to whether the first output pin of the first power circuit breaker and the second output switch of the second power circuit breaker are contacted to each other. The first output pin and second output pin are connected to one another by way of a node outside the power circuit breaker.
