Abstract

A device comprises an over-current reducing arrangement (7) which reduces over-current in response to an over-current detector (8). The reducing arrangement comprises several electric closing devices (9) connected between phase conductors (R,S,T) in the plant. These close to bring each individual phase conductor into electrical connection with a further phase conductor. During a fault, the phase conductors are short circuited to each other by the closing device.
