A movable fuse socket support including a fuse holder which is adapted to be attached to bus bars is provided on the underside of a socket plate with fastening means which cooperate with the bus bar to establish a firm connection between a separate contact plate covering the underside of the fuse holder and the bus bar. The fuse of universal contact plates suitable both for the gauge ring system and the gauge screw system is achieved in that the contact plate has a tapped bore coinciding with the center axis of the fuse holder, that adjacent the fuse holder the underside of the socket plate has a recess in which is disposed a C-shaped clamp including a setscrew which is adjustable from the uppersdie of the socket plate, that the C-shaped clamp embraces one end of the contact plate together with the bus bar which is in abutting relationship with the underside of the contact plate, that the opposite end of the contact plate is inserted into a groove provided in the socket plate and is retained therein, and that a setscrew tightens the contact plate and the bus bar relative to each other and against the lower arm of the C-shaped clamp.
