| Zusammenfassung: | A residual-current-operated protective arrangement includes a residual-current-operated protective device that has a core and an evaluation coil. A control device is provided that has a detection unit for detecting an electric current flowing through the evaluation coil. The residual-current-operated protective arrangement has a test winding that is inductively coupled to the evaluation coil via the core and the control device has a testing unit for impressing a predetermined test current into the test winding. |
