This metal-enclosed gas-filled switchgear units has at least two busbar systems and a circuit breaker (6) which respectively has per pole a pole axis (13) and at least one arcing chamber (66) built into a pole housing constructed as a metal enclosure. The pole axes (13) are arranged perpendicular to a foundation (4) and lie in a first plane. Furthermore, the switchgear units respectively has an electrically conductive connection, extending along a connecting axis (15, 81, 82), between the live arcing chamber (66) of the respective pole and each of the busbar systems. The aim is to provide a metal-enclosed gasfilled switchgear units in which the insulation and the fastening of the arcing chambers of the circuit breaker poles are substantially simplified and reduced in cost. This is achieved when the arcing chamber (66) is connected in a force-closed fashion to the at least two current terminals (21, 22, 70) and the arcing chamber (66) is positioned by these alone in the metal enclosure.
