Patent ID: 8243453

Claim:
An electrical installation comprising a circuit breaker, a plurality of connections of conductors to said circuit breaker, a plurality of walls, an electrically conductive element and a cooling arrangement for the electrically conductive element in the electrical installation, the cooling arrangement comprising a casting body for electrically isolating the electrically conductive element, in which the casting body has a central portion surrounding the electrically conductive element and an outer wall, part of which forms a non-flat contact surface that is form-fitted with at least a part of a heat conducting wall of the electrical installation, in which the outer wall of the casting body is provided with an electrically conductive layer, in which the heat conducting wall is a back wall of the plurality of walls of the electrical installation, and in which the electrically conductive layer is parallel to and abuts the back wall at the non-flat contact surface and extends beyond the central portion of the casting body.
