ABSTRACT:
The invention relates to a gas deionization device and an arc extinguishing chamber notably for a multipole low voltage circuit breaker with a molded case. A porous shield comprising one or more superposed metallic wire cloths. Each cloth is formed by a criss-crossing of straight wire yarns spaced apart from and parallel to one another with tight joined undulated wire yarns that extend appreciably perpendicular to the straight wire yarns, and pass alternately over and under at least one of the successive straight wire yarns. At least three superposed wire cloths have progressive mesh openings.
