Abstract

A pole part of a circuit breaker arrangement comprising an insulation housing (1 ) for accommodating a vacuum interrupter insert (5) containing a pair of corresponding electrical switching contacts (4, 6) wherein a fixed upper electrical contact (4) is connected to an upper electrical terminal (2) molded in the insulation housing (1) and a movable lower electrical contact (6) is connected to a lower electrical terminal (3) of the insulation housing (1) via an electrical conductor (7) which is operated by an adjacent pushrod (8) wherein the lower electrical terminal (3) is connected to a ring shaped heat transfer shield (9-9'') arranged along the inner wall or at least partly inside the wall of the insulation housing (1 ) surrounding the pushrod (8) and/or the distal end of the movable lower electrical contact (6).
