Fault-current protection device and method for switching switch contacts of the fault-current protection device

摘要

Residual current device (1) for detecting fault currents in a low-voltage network with a protective conductor (PE), a neutral conductor (N) and at least one phase conductor (L; L1, L2, L3), the residual current device (1) comprising a protective conductor (2), a Neutral conductor (4) and at least one phase conductor (3, 3 ', 3 ") for electrical connection to the low-voltage network, the residual current device (1) further comprising a protective conductor switching contact (5) for interruptible and interruptible interruption of the protective conductor (2) Residual current device (1), at least one phase conductor switching contact (6, 6 ', 6 ") for interruptible and interruptible interruption of at least one phase conductor (3, 3', 3") of the residual current device (1) and a neutral switching contact (7 ) for switching on and off the neutral conductor (4) of the residual current device (1), wherein at least one switching means (8, 9, 9 ', 9 ", 10) is provided in order to connect the switching contacts (5, 6, 6 ', 6 ", 7). It is inventively provided that the protective conductor switching contact (5) independently of the neutral contact (7) and the at least one phase-switching contact (6, 6 ', 6 ") is switchable.
