Abstract
A ground fault circuit interrupter has a residual current transformer (,) which is connected via evaluation and tripping electronics (,) to a open circuit shunt release (,), the open circuit shunt release (,) via a breaker mechanism (,) actuating the main contacts (,) in the leads (L,, L,, L,) to be monitored, the line voltage supply of the evaluation and/or tripping electronics (,) and/or the open circuit shunt release (,) being connected electrically separably to a least two leads (L,, L,, L,, N) via auxiliary contact apparatus (,). In this way the line voltage supply for the evaluation and/or the tripping electronics (,) and the open circuit shunt release (,) can be interrupted independently of the line-side or load-side terminal with respect to the main contacts (,) and is still ensured when one or two leads (L,, L,, L,, N) are interrupted.
