Abstract
Monitoring circuit for monitoring a voltage, comprising a coil, which is incorporated in a first current branch to be connected to the voltage to be monitored, and an auxiliary relay, the actuating winding of which is incorporated in a second current branch connected in parallel to the first current branch. In the first current branch a first make contact of the auxiliary relay is connected in series with the coil. In the second current branch a first resistor is connected in series with the actuating winding of the auxiliary relay. A series circuit consisting of a second resister and a second make contact of the auxiliary relay is connected in parallel to the actuating winding of the auxiliary relay.
