Beschreibung
Zusammenfassung:	The invention concerns a device (1) for protecting electrical equipment against overloads comprising: a protective unit (2) having at least one first and one second pole (2A, 2B), these poles (2A, 2B) being electrically connected to the equipment via connecting means (3); a functional coupling means (5) of the protective unit (2) for coupling to the connecting means (3), and; a thermal disconnecting means (4) functionally joined to said protective unit (2) for interrupting the electrical connection between the unit (2) and the equipment when the temperature of the unit reaches a predetermined critical value. The invention is characterized in that the coupling means (5) is designed for exerting a tightening of the protective unit (2) in a manner that ensures the electrical connection of the poles (2A, 2B) to the connecting means (3). The invention also relates to an electrical device for protecting against overloads.
