Abstract

A switching device including a switching chamber, in which a stationary switching piece is arranged opposite a movable switching piece, where the stationary switching piece is placed on a plastic carrier part and this component combination of stationary switching piece and plastic carrier part is configured as an exchangeable switching piece assembly.

First claim

The invention claimed is:

1. A switching device comprising:
a switching chamber;
a movable switching piece;
a stationary switching piece arranged in the switching chamber and opposite the moveable switching piece; and
a plastic carrier part having mutually parallel recesses arranged on mutually parallel sides and externally disposed along a longitudinal edge of said mutually parallel sides, said mutually parallel recesses accommodating arc splitters, and the stationary switching piece being fitted to the plastic carrier part;
wherein a component combination of the stationary switching piece when fitted to the plastic carrier part comprises an exchangeable switching piece assembly.

2. The switching device as claimed in claim 1 , wherein the plastic carrier part includes two mutually parallel sides, which are interconnected by a first connecting side.

3. The switching device as claimed in claim 2 , further comprising:
a second connecting side arranged at a distance from and parallel to the first connecting side such that, between the first and second connecting sides, a recess is formed, into which one arm of a U-shaped stationary switching piece is inserted.

4. The switching device as claimed in claim 1 , further comprising:
an arc quenching bucket; and
two mutually parallel guide slots arranged on the mutually parallel sides for accommodating the arc quenching bucket.

5. The switching device as claimed in claim 1 , wherein the plastic carrier part is manufactured from a high-temperature thermoplastic material.

6. The switching device as claimed in claim 1 , wherein the plastic carrier part is manufactured from Duroplast.

7. The switching device as claimed in claim 1 , wherein the switching device is a contactor.

8. The switching device as claimed in one of claim 1 , wherein the switching device is a power circuit-breaker.

9. The switching device as claimed in one of claims 1 wherein the switching device is a compact motor feeder.
