Abstract

An electric switching arrangement disposable in an arcing chamber, the electric switching arrangement including a busbar having a termination surface, a moving contact, a fixed contact carrier having a contact facing carrier, and a fixed contact disposed on the fixed contact carrier at a distance from the termination surface and coupled to the termination surface. The electric switching arrangement further including a ferromagnetic switch arc splitter non-positively disposed on the fixed contact carrier.

Claims (19)

1. An electric switching arrangement disposable in an arcing chamber, the electric switching arrangement comprising:

a busbar having a termination surface;

a moving contact;

a fixed contact carrier having a contact facing carrier;

a fixed contact disposed on the fixed contact carrier at a distance from the termination surface and electrically coupled to the termination surface; and

a ferromagnetic switch arc splitter disposed on the fixed contact carrier,

wherein the arc splitter includes an elongated base element having a mounting window, at least one baffle plate, and a discharge horn, the at least one baffle plate being disposed at a front portion of the elongated base element at a distance from the termination surface and the discharge horn being disposed at a rear portion of the elongated base element in a vicinity of the termination surface.

2. The electric switching arrangement as recited in claim 1 , further comprising a receiving tab disposed on the contact facing carrier and projecting towards the termination surface from a cross strut disposed on the fixed contact carrier,

wherein the mounting window includes an upper edge and a lower edge, the upper edge including an upper placement surface disposed above the receiving tab and the lower edge including a lower placement surface disposed below the receiving tab, wherein a distance between the upper and lower placement surfaces is less than a thickness of the receiving tab.

3. The electric switching arrangement as recited in claim 2 , wherein a surface of the cross strut is disposed a first distance below a reference surface, the reference surface being defined by a contact portion of a surface of the receiving tab, and

wherein a first of the at least one baffle plate includes a catch, the catch being disposed a second distance below the reference surface, the second distance being greater than the first distance.

4. The electric switching arrangement as recited in claim 3 , wherein the first distance is a length of the strut.

5. The electric switching arrangement as recited in claim 3 , wherein the second distance is a length of the catch.

6. The electric switching arrangement as recited in claim 3 , wherein a second of the at least one baffle plate includes a respective catch.

7. The electric switching arrangement as recited in claim 6 , further comprising a quenching plate stack disposed in the arcing chamber.

8. A method for mounting the switch arc splitter as recited in claim 3 , the method comprising the steps of:

sliding the switch arc splitter onto the receiving tab;

elastically deforming a front portion of the switch arch splitter towards the reference surface via a force exerted from below the reference surface so that the catch is displaced onto a plane defined by a surface of the cross strut; and

displacing the catch to lie on the surface of the cross strut via a force exerted in a plane defined by the reference surface towards the cross strut.
