Abstract
A residual current circuit breaker has a summation current transformer that has primary windings as well as a secondary and a tertiary winding, the secondary winding forming a circuit with an electronic trigger unit that is independent of the network voltage, and the tertiary winding forming a circuit with an electronic trigger unit that is dependent on the network voltage. The residual current circuit breaker may have an electronic control unit designed to actuate a switch upon predefinable actuation by the network voltage-dependent electronic trigger unit, and the switch, when in the actuated state, may interrupt contact of the secondary winding with the network voltage-independent electronic trigger unit and establishes contact of the tertiary winding with the network voltage-dependent electronic trigger unit.
