Abstract

The object of the invention is a device (1) for protecting a component (EB) against thermal overload. The device (1) has an actuating mechanism (B) which is brought into thermal contact with the component to be protected (EB) when in use, and which is capable of activating a switch (S) upon reaching a certain temperature Tswitch. The switch (S) can be used both as a disconnection switch and as a short-circuiting switch in relation to the component to be protected (EB), with the switch (S) furthermore having a selection mechanism (A) with which one can choose whether the switch (S) should be used as a disconnection switch or as a short-circuiting switch in relation to the component to be protected (EB).
