Abstract (en)
[origin: WO2007082775A1] In order to achieve thermomechanical overload protection with a broad adjustment range for protecting against overload currents, the live components carry an electrical current which is between the value of the overload current and zero. According to the invention, switching means are used which, in a preferred embodiment, switch the current, in parallel, from a first current branch to at least one second current branch, the parallel-connected at least one current branch carrying a partial current, which is between the value of the overload current and zero. In the associated overload protection device (102), contact means are provided which are associated with live components on two current branches (1, 2) which can be connected in parallel with one another, wherein at least one current branch can be switched on and off by the switching means. In an alternative embodiment, a first and a second current branch are connected electrically in series by switching means, as a result of which it is possible to switch over from an upper adjustment range to another, lower adjustment range of the broad adjustment range.
