Abstract: A current feedthrough seal assembly (1) for insertion into and sealing a wall opening (WO) of a climate chamber (KK) comprises a plastic core (10) formed in a step-like shape in an axial direction thereof so as to be inserted into the wall opening (WO) of the climate chamber (KK), so that, when inserted, substantially the whole of the plastic core (10) is located in the wall opening (WO), and a flange (11) is formed at an axial end of the plastic core (10) to protrude beyond the wall opening in the radial direction of the plastic core (10) to abut against one (I) of an internal or external wall (I, A) of the climate chamber (KK), at least two elongated power conducting members (20) accommodated in parallel to each other inside the plastic core (10) and extending through the plastic core (10) and a press ring seal (30) interposed between an inner peripheral surface of the wall opening (WO) and an outer peripheral surface of the plastic core (10) on an opposite axial side thereof with respect to the flange (11)
