ABSTRACT:
Device for the automatic reclosing of breakers, taking the form of an assembly (1) comprising a movable element (3) capable, as a result of a trip of the breaker, of being moved in order to actuate the setting member of the breaker so as to reclose it.
It is defined in that the said movable element (3) is composed of a piston (4) which is mounted inside a stationary housing or enclosure (2) and the movements of which are obtained as a result of the variations in volume of an expandable body contained inside the said enclosure (2), these variations being caused by the heat released by an electrical resistor (8) when it is made live.
