Device for interrupting non-short circuit currents only, in particular disconnector or earthing switch

A device for interrupting non-short-circuit currents only, the device comprising:

• at least two contacts movable in relation to each other between a closed state and an open state and defining an arcing region, in which an arc is generated during a current interrupting operation and in which an arc-quenching medium comprising an organofluorine compound is present, wherein
• a counter-arcing component is allocated to the arcing region and is designed for counteracting the generation of the arc and/or is designed for supporting extinction of the arc,
• a first contact of the at least two contacts being in the form of a piston,
• a second contact of the at least two contacts being in the form of a cylinder,
• the first contact being contained by the second contact,
• the first contact being slideably moveable in the cylinder,
• the piston comprising a front end facing the other contact and a resistive element in a region of the front end sandwiched in an axial direction of the piston between two regions of a material of lower resistance than the resistive element.
