A circuit interrupter has first and second contacts that are actuatable relative to each other between a closed position wherein a power source and a load are in electrical communication and an open position wherein the power source and the load are not in electrical communication. An arc extinguisher is also provided for extinguishing an arc that develops in the vicinity of the contacts. An electromagnetic coil, when energized, generates a magnetic field that permeates an area where the arc develops, the magnetic field urging the arc toward the arc extinguisher regardless of a polarity of the contacts. An auxiliary switch is operably connected to the contacts, such that upon movement of the contacts relative to each other from the closed position toward the open position, the auxiliary switch is activated so as to energize a circuit feeding power to the electromagnetic coil, thereby generating the magnetic field.

An electrical breaking module includes a non-magnetic, electrically insulating casing housing, a fixed contact and a movable contact defining between them a breaking zone in which an electric arc extends at its origin when the electrical circuit is opened. A magnetic blow-out device is provided with at least one magnetic field source arranged in a breaking chamber, opposite the breaking zone to move and stretch the electric arc in a direction substantially perpendicular to the breaking plane towards the housing. The magnetic blow-out device also includes a non-magnetic, electrically insulating deflector, arranged in the breaking chamber to occupy most of the space between the breaking zone and the casing, so as to create at least one arc confinement zone, in which the electric arc when magnetically blown is deflected and constrained to promote its cooling and extinction.
