Abstract
A multipolar electrical protection device has a disconnecting block with separable contacts containing at least one movable contact finger, a switching mechanism able to move the contact fingers, and an electronic tripping system that drives the mechanism. The protection device has a pyrotechnic actuation system including: a pyrotechnic actuator; firing pins positioned facing the contact fingers and each able to be moved to a pressed position in which it pushes a contact finger; a motion transmission system for transforming the movement of a mobile part of the pyrotechnic actuator to the deployed position thereof into a simultaneous movement of all of the firing pins to the pressed position. The tripping system is able to activate a pyrotechnic actuator when it detects an electrical fault.
