Abstract
A low-voltage switching device includes a housing in which power-electronic components are arranged in the region of ventilation of a fan. In an embodiment, the power-electronic components operate under temperature regulation by virtue of an air flow that is guided asymmetrically proceeding from the fan. Therefore, the low-voltage switching device can be operated at a nominal device current range of up to 650 A as the result of the asymmetrically guided air flow.
