Abstract (en)
[origin: ES8604003A1] The miniature circuit breaker has a moulded insulating housing incorporating an arc chamber (38) containing a pair of separable contacts (20,22). The arc chamber (38) communicates with an arc extinction chamber (30) and is separated by an insulating partition wall (44) from the chamber containing the operating mechanism. - The partition wall (44) is shaped so that it follows the equipotential lines provided between the spaced breaker contacts (20,22) over at least part of its length. Pref. the partition wall (44) extends between the two walls of the arc chamber (38) on the side of the fixed contact (22) and the mobile contact (20) respectively.
