Abstract

The invention relates to a vacuum interrupter arrangement for a medium voltage circuit breaker comprising a vacuum housing (4) within which a pair of electrical contacts (2a 2b) are coaxially arranged and concentrically surrounded by the cylindrical shaped vacuum housing (4) wherein the electrical contacts (2a 2b) are formed in a type of TMF contacts each comprising a slotted cup shaped contact part (9a; 9b) which is attached to the distal end of a contact shaft (8a; 8b) and which is covered by a contact ring (10) disposed on the rim (11) of the cup shaped contact part (9a; 9b) wherein each cup shaped contact part (9; 9'; 9'; 9''; 9'') is provided with a vertical inward bending towards the contact ring (10) wherein the outer diameter of the bottom section of the cup shaped contact part (9; 9 ; 9'; 9''; 9 ') is larger than the outer diameter of its rim section (11) in order to alter the Lorentz force to a respective inward direction.
