Claim Text:
1. 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 connectable to an electrical conductor, the protection device comprising: thermal monitoring sensors, for each electrical conductor, which are able to detect a temperature increase, at each connection terminal, to above a predetermined threshold, wherein the fire protection device is mechanically fastenable to the starter-controller device via at least one mechanical connection member, wherein the thermal monitoring sensors comprise one or more temperature sensors able to sense a temperature in first one or more hollow housings of the starter-controller device situated near a connection terminal of a conductor, the fire protection device including an injection device, electrically connected to said one or more temperature sensors, configured to inject a fire extinguishing agent toward the first one or more hollow housings once the one or more temperature sensors have detected a temperature above the predetermined threshold, and wherein the fire protection device further comprises a trigger element, kept in a first idle position by a fastening piston as long as the one or more temperature sensors indicate a temperature below the predetermined threshold, said trigger element is able to move toward a second locking position when the fastening piston moves away from the trigger element, the movement of the fastening piston from a contact position with said trigger element to a non-contact position with said trigger element being done following the release of the fire extinguishing agent.
