Abstract

The object of the invention is a thermal overload protection device (22) for protecting an electric component (10), in particular an electronic component, wherein the overload protection device (22) has a short-circuit unit (24) for short-circuiting connections (12, 14) of the component (10), and an actuating member (26) actuating the short-circuit unit (24) in a temperature sensitive manner. According to the invention it is provided that the short-circuit unit (24) is attached to a circuit path support (16) in at least one area (28), and is supported in at least another area (30) on the component (10) disposed on the circuit path support (16) via the actuating unit (26), and/or at least one of the circuit paths (18, 20) contacting one of the connections (12, 14) to be short-circuited.The invention further relates to a respective arrangement (36) having a circuit path support (16), at least one component (10) disposed thereupon, and at least one assigned overload protection device (22).
