An anti-fire protection device for a starter-controller device of an electrical installation is able to be connected to an electrical power conductor and includes thermal monitoring of the electrical power conductor to detect a temperature rise of greater than a predetermined threshold. This anti-fire protection device can be fixed mechanically to the starter-controller device via at least one mechanical linking member. The thermal monitoring includes at least one temperature sensor and a cartridge including a fire extinguishing agent and at least one injection element, situated on the same face of the protection device as the temperature sensor, the cartridge being situated inside the protection device and connected to the temperature sensor, the injection element being able to inject the fire extinguishing agent towards the electrical power conductors subsequent to a detection, by the temperature sensor, of a temperature of greater than the predetermined threshold.

Device for anti-fire protection of a starter-controller device of an electrical installation

An electric switching apparatus including fixed contacts respectively supported by an upstream support and a downstream support and electrically connected to an upstream power line and to a downstream power line, respectively, the fixed contacts cooperating with respective upstream and downstream mobile contacts, each of the mobile contacts being supported by a support, the supports movable simultaneously in translation by a contact carrier controlled by an actuator. This apparatus includes a device for transforming, during a device opening operation in the presence of a microweld between one of the mobile contacts and the associated fixed contact, the movement in translation of the support associated with the mobile contact in a combined movement in translation and rotation of the mobile contact so as to exert at the points of contact between the mobile contact and the fixed contact a shear force capable of breaking the aforementioned microweld.

Electric switching apparatus

The invention relates to a fire protection device () for a starter-controller device () of an electrical installation, the starter-controller device () comprising at least one connection terminal, each connection terminal being adapted to be connected to an electrical conductor, the protection device () comprising thermal monitoring means for the or each electrical conductor adapted to detect a temperature increase, at each connection terminal, above a predetermined threshold. This protection device is suitable for being mechanically fastened to the starter-controller device () via at least one mechanical connection member (). The thermal monitoring means comprise at least one temperature sensor () able to sense a temperature in a first hollow housing () of the starter-controller device () situated near a connection terminal of a conductor. This protection device further includes an injection device (), electrically connected to said at least one temperature sensor (), adapted to inject a fire extinguishing agent toward the first hollow housing(s) () once the temperature sensor () has detected a temperature above the predetermined threshold.

Fire protection device of an electric installation starter-controller device

This switching device comprises at least one pair of fixed contacts and, for each pair of fixed contacts, a movable contact that is movable between a closed position and an open position. A contact holder capable of holding in place each movable contact is also provided. The contact holder is movable along a vertical direction between a first position corresponding to the closed position of each movable contact and a second position corresponding to the open position of the or each movable contact. The device also includes a plate capable of applying a force on the movable contact holder so as to move it between its first and second positions. The plate is movable relative to the movable contact holder. The device includes a sensor capable of measuring the movement of the movable plate relative to the movable contact holder, during the actuation of the movement of the plate in order to drive the movement of the contact holder from its first position to its second position. A detection member for detecting a malfunction in the switching device based on at least one value measured by the sensor is also provided.
