    wobei das Gehäuse (11) zwei verschiedene Zusatzteile (22) umfasst, wobei jeder Zusatzteil (22) wenigstens eine mittlere Aufnahme (23) begrenzt, und dadurch dass die Klemme (14), die in der wenigstens einen mittleren Aufnahme (23) eines der zwei Zusatzteile (22) montiert ist, zu einer der zwei Reihen gehört und die Klemme (14), die in der wenigstens einen mittleren Aufnahme (23) des anderen der zwei Zusatzteile (22) montiert ist, zu der anderen der zwei Reihen gehört, wenn die zwei Zusatzteile (22) ihre Funktionskonfigurationen einnehmen.
  2. Elektrische Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die wenigstens eine Auflagefläche fest mit einer Klammer (24) verbunden ist, die von dem Gehäuse (11) sowie der Kontaktfeder (16) unabhängig ist und Befestigungselemente umfasst, die so konfiguriert sind, dass sie die Klammer (24) auf der Kontaktfeder (16) montieren können, insbesondere in reversibler Art.
  3. Elektrische Einrichtung nach einem der Ansprüche 1 oder 2, dadurch gekennzeichnet, dass die Montageelemente (25, 26) des wenigstens einen Zusatzteils (22) auf dem Hauptteil (20) so ausgestaltet sind, dass die Befestigung des wenigstens einen Zusatzteils (22) eine relative Verschiebung zwischen dem Zusatzteil (22) und dem Hauptteil (20) gemäß einer zweiten Richtung (D2) erfordert, die quer zu der ersten Richtung (D1) ausgerichtet ist.
  4. Elektrische Einrichtung nach Anspruch 3, dadurch gekennzeichnet, dass die erste Richtung (D1) und die zweite Richtung (D2) parallel zu der Ebene ausgerichtet sind, in der Befestigungselemente (12) des Gehäuses (11) auf einer Stütze außerhalb der elektrischen Einrichtung, wie etwa eine Stützschiene eines Schaltschranks, positioniert sind, falls die elektrische Einrichtung ein Schütz ist oder ein Gehäuse eines Schützes, falls die elektrische Einrichtung ein Hilfsblock ist.
  5. Elektrische Einrichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass die Montageelemente (25, 26) des wenigstens einen Zusatzteils (22) auf dem Hauptteil (20) erste Montageglieder (25), die fest mit dem Hauptteil (20) verbunden sind, und zweite Montageglieder (26) umfasst, die fest mit dem Zusatzteil (22) verbunden sind, wobei die ersten und zweite Montageglieder (25, 26) durch Einrasten miteinander zusammenwirken.
  6. Elektrische Einrichtung nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, dass das Gehäuse (11) eine Schutzabdeckung (19), die in einem Teil ausgebildet ist, das von dem Hauptteil (20) und von dem wenigstens einen Zusatzteil (22) unabhängig ist, und Zusammenbauelemente (27, 28) umfasst, die eine abnehmbare Befestigung der Schutzabdeckung (19) auf dem Hauptteil (20) und auf dem wenigstens einen Zusatzteil (22), welcher die Funktionskonfiguration einnimmt, in einer Betriebskonfiguration sicherstellt, in der die Schutzabdeckung (19) den Hauptteil (20) und den wenigstens einen Zusatzteil (22) ganz oder teilweise abdeckt, sodass ein manueller Zugriff auf die Direktsteckklemmen (14), die von dem Hauptteil (20) und von dem wenigstens einen Zusatzteil (22) getragen werden, untersagt wird.
  7. Elektrische Einrichtung nach Anspruch 6, dadurch gekennzeichnet, dass die Zusammenbauelemente (27, 28) der Schutzabdeckung (19) so konfiguriert sind, dass die Befestigung der Schutzabdeckung (19) eine relative Verschiebung zwischen der Schutzabdeckung (19) und dem Hauptteil (20) gemäß einer dritten Richtung (D3) erfordert, die quer zu der ersten Richtung (D1) ausgerichtet ist.
