An arc control device including arc splitters and a cassette including a first part and a second part and an insulating material are also provided. The arc splitters are disposed in a positive-locking manner in an interior of the cassette, the contact arm and a part of the conductor rail including the stationary contact extending into the interior of the cassette, and the current loops being disposed in a positive-locking manner at outer walls of the cassette. An assembly of the cassette, the arc splitters and the conductor rail is received in a positive-locking manner by inner surfaces of a switching device enclosure.
