Abstract (en)
[origin: US2009224864A1] A switching device has an input terminal and an output terminal for connection to electrical conductors, and two switching contacts which, when closed, close a current path between the input terminal and the output terminal. An overcurrent trigger device which includes a bimetallic element heated by an electric current flow is provided for disconnecting the two switching contacts. A thermal insulator is arranged in the attachment region of the bimetallic element for reducing heat transfer from the bimetallic element as well as for increasing the accuracy and the degree of reproducibility for triggering the switching device. The switching device can be implemented as a circuit breaker.
