Abstract
An electromagnetic contactor is fitted with an electromagnet sensitive to overcurrents, to cause the limitation and cut-off of excess currents. A movable contact bridge is controlled by a spring which holds it against the fixed contacts, and is struck by at least one component which is not connected to it, and which is positioned between it and the armature of the control electromagnet.
