Fault current limiter arrangement

A fault current limiter arrangement for a low, medium and high voltage electricity grid, comprising:

• a fault current limiter unit arranged in line with a circuit breaker unit for interrupting a current flow after the fault current limiter unit has limited current flow in a detected fault event, the circuit breaker unit including a fixed electrical contact connected to a lower electrical terminal and a movable electrical contact connected to an upper electrical terminal,
• a metallic pushrod for acting on the movable electrical contact of the circuit breaker unit, and
• a metallic housing sleeve surrounding the pushrod and electrically connected to the upper electrical terminal,
• wherein the fault current limiter unit includes a movable electrical sliding contact part electrically arranged between the upper electrical terminal of the circuit breaker unit and the movable electrical contact of the circuit breaker unit, and which is movable between a short circuit position adjacent to the upper electrical terminal and a remote position from the upper electrical terminal for providing a maximum electrical resistance for the current flow, the pushrod and housing sleeve being configured to increase electrical resistance in connection with the movable electrical sliding contact part.
