Abstract: The invention relates to an electric assembly to be mounted on a top-hat rail, comprising: an electric current supply component (200): a multi-layered support (206) including a metal plate (300), a conductive layer (302) for electrically contacting the electric current supply component (200) and an electric insulation layer (304) which is arranged between the metal plate (300) and the conductive layer (302); the electric current supply component (200) is connected in an heat-conductive manner to the metal plate (300) in order to withdraw thermal energy from the electric current supply component (200).
