ABSTRACT:
A rating plug may be provided with an electrical coding such that unsuitable identification of the rating plug is not transmitted to the trigger unit, but rather the attempt to make use of such a rating plug leads to a signal. The signaling unit is arranged on the housing of the low-voltage power breaker, or on the trigger unit. Thus, if the rating plug is the wrong rating plug, wrong contact connection and a defective rating plug may be recorded.
