Abstract
A circuit breaker comprises a plurality of pole compartments juxtaposed inside an insulating case, in each of which compartments there are arranged an arc extinguishing chamber and at least one pair of separable contact parts comprising at least one movable contact part, at least two of said pole compartments being contiguous and separated from one another by a partition. The separating partition of the twinned poles comprises a communicating aperture of dimensions and location such that it is able to appreciably influence the distribution of the arcing energy between the two compartments when the latter are connected in parallel. A circuit breaker with a high breaking capacity is thus obtained from a standard multipole circuit breaker of lower breaking capacity.
