Abstract
A arcing chamber housing is disclosed for a circuit breaker with a double turning contact breaker. The arcing chamber housing (1) is composed of two housing modules (2, 3) and an extinguishing chamber (19) is arranged in the area of the fixed contact pieces (6, 7) to extinguish the arcs which are formed between the contact pieces of the double turning contact breaker. In order to obtain a arcing chamber housing (1) which is easy and economical to produce, with extinguishing chambers (19) which have a reproducible extinguishing behavior once the arcing chamber is assembled, the two housing modules (2, 3) are substantially L-shaped parts whose inner marginal surfaces (4, 5) face each other. The first parts (17, 18) of the housing, which correspond to the first branches of the L-shaped housing modules (2,3), are designed as extinguishing chambers (19). Also disclosed are the housing modules (2, 3) used to produce such a arcing chamber housing.
