Abstract
An accessory device for low or medium voltage electric applications includes a casing and electronic means including one or more current sensors for detecting current flowing in an electric cable. The top shell of the casing includes an external recess having a cable seat for accommodating the electric cable in a transversal position with respect to the casing. The cable seat has a cable coupling surface adapted to mechanically couple with the electrical cable. The accessory device includes a holder element mechanically coupleable with the top shell in the external recess. The holder element includes one or more holding surfaces. Each of the holding surfaces is overlapped and mechanically coupled with the electric cable, when the holder element is positioned in the external recess in a corresponding accommodating position that is selectable depending on the size of the electric cable. Each of the holding surfaces, when overlapped and coupled with the electric cable, cooperates with the cable coupling surface to hold the electric cable in a given position with respect to the current sensors.
