Abstract

Es wird ein Erdungsschalter (10) insbesondere für eine Mittelspannungsschaltanlage beschrieben, der mit einem Festkontakt (11) und einem beweglichen Kontakt (12) versehen ist, wobei der bewegliche Kontakt (12) von einer geöffneten in eine geschlossene Stellung und umgekehrt bewegbar ist. Erfindungsgemäß weisen der Festkontakt (11) und der bewegliche Kontakt (12) Abbrandkontakte (21, 28) auf.

Figure imgaf001
A grounding switch (10) is described, in particular for a medium-voltage switchgear, which is provided with a fixed contact (11) and a movable contact (12), wherein the movable contact (12) can be moved from an open to a closed position and vice versa. According to the fixed contact (11) and the movable contact (12) burn-off contacts (21, 28).
