Arrangement and switching device with contactless current measuring capability

A current measuring arrangement, comprising:

• a first electrical conductor having a first resistance,
• a second electrical conductor, which is switched in parallel with the first electrical conductor and which has a second, higher resistance, wherein the first resistance and the second resistance each are below 0.1Ω between connection points between the first electrical conductor and the second electrical conductor;
• a hall sensor, which is configured to measure a current through the second electrical conductor, and
• a calculation unit, which is connected to the hall sensor and which is configured to calculate a total current through the first electrical conductor and the second electrical conductor based on the current measured by the hall sensor and based on a ratio between the first resistance and the second resistance or based on a ratio between the total resistance, which is the sum of the first resistance and the second resistance, and the second resistance.
