Abstract
In a vacuum contactor, the armature is initially deflected from an armature rest position through an initial movement distance, and then through a driving movement distance to an armature operating position when a pull-in current is applied to a drive coil. An operating element is deflected from an element rest position to an element operating position by the armature only while the latter is passing through the driving movement distance. This makes it possible to achieve a good tripping characteristic of the vacuum contractor.
