Abstract

The separation partition (44) of the arc formation chamber (38) from the mechanism of a miniature circuit breaker is formed so as to follow at least on a part of its length some equipotential lines generated between the separated contacts (20, 22) of the circuit breaker. This particular shape of the partition (44) increases the insulating level of the appliance after a fault elimination.
