Abstract

An electric arc extinction chamber system, especially for low-voltage circuit breakers of very high nominal current intensities, wherein parallel electric arc extinction chamber inserts are provided in a housing extending over the entire width of a pole-face arc. The housing of the chamber is sub-divided by a partition wall or several partition walls which are embodied as components of the housing. The compartments thus formed receive arc splitter cartridges.
