Abstract: A sub-module is disclosed. A sub-module according to an embodiment of the present invention comprises a short-circuiting control part. The short-circuiting control part comprises a movable member slidably coupled to a frame on which capacitor assemblies are seated. A variable connector is coupled to the movable member. Moreover, a plurality of short-circuiting blocks are arranged on the frame while being spaced away from each other. When the movable member has slid, the variable connector comes into contact with one or more short-circuiting blocks adjacent to each other to be electrically conductive. The short-circuiting blocks are connected to the capacitor assemblies, respectively, to be electrically conductive. Therefore, a plurality of capacitor elements can be short-circuited simultaneously only by moving the movable member.
