An apparatus (10) for protecting an electrical device comprises two temperature-dependent switching mechanisms (12, 13) each having at least two temperature-dependent switch conditions, and three external terminals (15, 16, 17). The two switching mechanisms (12, 13) are arranged directly in a common housing (21) in such a way that each switching mechanism (12, 13), as a function of its temperature, connects a first or second external terminal (16, 17), associated with it, directly to a third external terminal, serving as center terminal (15), that is common to both switching mechanisms (12, 13).
