Claims

[Scope of utility model registration request]

A reversing contact pressure spring is tension-suspended between the movable contact and the armature, which are connected via a contact holder, and an electric circuit is passed through between the armature and the yoke disposed opposite to it. It has a plurality of contact opening mechanisms that reversely open the movable contact by a suction action of an armature, and a contact link connected to these contact opening mechanisms, and the contact opening/closing mechanism is operated by a common opening/closing spring. comprising an opening/closing/trip link mechanism that operates to open, and a reset protrusion that is provided corresponding to each of the movable contacts and that collides with each of the movable contacts when the contact opening/closing mechanism is opened, reversing and resetting them; A multipolar circuit breaker characterized in that a step is provided between the movable contacts and the reset protrusion so that the movable contacts are mutually inverted and reset in stages.
