摘要： A switch unit for a DC circuit is disclosed, which includes a first switch contact, and a second switch contact, which is movable between a first position, wherein the first switch contact contacts the second switch contact, and a second position, wherein the second switch contact is separated from the first switch contact. A positioning element to position an arc chute on the switch unit, the arc chute comprises a plurality of substantially parallel metal plates, the positioning element arranged to guide an arc, which is created between the first switch contact and the second switch contact, into the arc chute in an arc displacement direction in order to be extinguished. At least one gas emitting element, wherein at an interruption operation of the circuit breaker at its nominal current, the arc between the first switch contact and the second switch contact vaporizes a portion of the gas emitting layer.

摘要： An arc chute for a DC circuit breaker is disclosed which includes at least one stack of a plurality of substantially parallel metal plates, the at least one stack defining a first axis A in parallel to a stacking direction; an arc space adapted to allow an arc to extend along the first axis, wherein a second axis traversing in parallel to the metal plates the at least one stack and the arc space substantially orthogonal to the first axis. Further, an arc-chute housing having at least one side wall, the at least one side wall being substantially parallel to the second axis, wherein the distance between the at least one sidewall and the metal plates is, for example, less than 5 mm, such as less than 2 mm.
