Abstract (en)
[origin: WO0103153A1] A switching contact arrangement (5) of a low voltage circuit breaker (1) has a stationary contact group (7) and a moving contact group (10) that interacts with the same. These contact groups (7, 10) have interacting main contacts (20, 22) and interacting intermediate contacts (21, 23) and arcing contacts (26, 32). The two contact groups (7, 10) are also provided with an arcing horn (25, 31) for conducting an arc into an arcing chamber (6).The arcing contacts are integrated into the arcing horns (25, 31). Only the main contacts are configured as contact facings, the remaining contact points being formed by conductor rails (3, 4) or arcing horns (25, 31). The inventive switching contact arrangement (5) is characterized by its simple structure and by an increased mechanical and electrical service life. The switching times are also particularly short.
