Abstract
A breaker device for connecting in an electrical circuit, the device includes a pyrotechnic initiator and a body having present therein: a pressurizing chamber in communication with an outlet from the pyrotechnic initiator; at least one electrically conductive portion for connection to the electrical circuit; at least one fusible element connected in series with the conductive portion, the initiator being connected to the terminals of the fusible element and the fusible element being configured to trip when the current passing through it exceeds a predetermined value, thereby actuating the initiator; and a movable breaker element; the pyrotechnic initiator being configured to cause the breaker device to pass from a current-passing first configuration to a circuit-breaking second configuration, the movable breaker element being moved on passing from the first configuration to the second in order to disconnect the conductive portion.
