THERMAL TRIP DEVICE, SWITCHING DEVICE, THERMAL MAGNETIC CIRCUIT BREAKER AND METHOD FOR PROTECTING AN ELECTRIC CIRCUIT

摘要

A thermal trip device, of a thermal magnet circuit breaker is disclosed for protecting an electrical circuit from damage by overload, a switching device and a thermal magnetic circuit breaker including at least the thermal trip device are disclosed. In at least one embodiment, the thermal trip device includes at least a bimetal element arranged with a first end at a current conductive element to conduct electrical current and arranged with a second end at a tripping slide adapted to interrupting a current flow. The at least a bimetal element is connectable with a linking element extending between the bimetal element and the current conductive element to redirect the electrical current at least partially. Furthermore, a method is disclosed for protecting an electric circuit from damage by overload by use of the thermal trip device of a thermal magnet circuit breaker.
