Thermal trip device, switching device, thermal magnetic circuit breaker and method for protecting an electric circuit

摘要

The present invention relates to a thermal trip device of a thermal magnet circuit breaker for protecting an electrical circuit from damage by overload, a switching device and a thermal magnetic circuit breaker having at least the thermal trip device mentioned above, wherein the thermal trip device has at least a bimetal element in order to be arranged with its first end at a current conductive element for conducting electrical current and in order to be arranged with its second end at a tripping slide adapted to interrupting a current flow, wherein the bimetal element is able to be connected with a linking element extending between the bimetal element and the current conductive element in order to redirect the electrical current at least partially. Furthermore, the present invention relates to a method for protecting an electric circuit from damage by overload by means of the thermal trip device of a thermal magnet circuit breaker.
