Abstract
In order to form an overcurrent switching apparatus for medium-voltage or high-voltage applications with a current detection device for changing over a contact system associated with them from a first state to a second state in the event of a threshold current being exceeded, the switching properties of which overcurrent switching apparatus are precise, an actuating device is disposed downstream of the current detection device, which is in a first current branch, via a coupling device. The actuating device is configured to change over the contact system, which is in a second current branch, from the first to the second state.
