Electric device for heating, in particular a motor vehicle

摘要

The device has a contact layer (35) arranged in a contact region between an electrical heating unit (2) and an electrical contact device. A balancing unit (12) balances mechanical voltages in the contact region of the electrical heating unit and the electrical contact device. The balancing unit is formed by an adhesive agent (37) i.e. chromium, which is arranged between the contact layer and the electrical heating unit. A reduction unit (39) is formed by an intermediate layer (36) that is arranged between the contact layer and the adhesive agent.
