Claim 13:
14. A power distribution apparatus, comprising
a circuit breaker, and
a reverse power connection preventing circuit comprising a diode and an actuation unit that are connected in series, provided within the circuit breaker,
wherein the diode is a two-terminal component having a first diode terminal and a second diode terminal, wherein the actuation unit has a first actuation unit terminal and a second actuation unit terminal, wherein the second diode terminal and first actuation unit terminal are connected, and wherein an undivided current path is provided between the first diode terminal and second actuation unit terminal, and
wherein, inside the circuit breaker, the diode and the actuation unit are configured to connect a positive input terminal and a negative input terminal of a circuit breaker, a positive electrode of the diode is connected to the negative input terminal of the circuit breaker, and a negative electrode of the diode is connected to the positive input terminal of the circuit breaker, with the undivided current path being provided between the positive input terminal of the circuit breaker and the negative input terminal of the circuit breaker and through the diode and actuation unit such that the diode is configured to conduct in a case where current flows from the negative terminal of the circuit breaker, through the diode from the positive electrode to the negative electrode, and to the positive terminal of the circuit breaker, the actuation unit is configured to either prevent closing of the circuit breaker when the diode conducts, or is configured to perform an alarm prompt when the diode is conducts, and the reverse power connection preventing circuit is connected between the positive input terminal and the negative input terminal of the circuit breaker.
