Abstract

The present method relates to a method for checking a multi-pole electrical circuit breaker. The multi-pole electrical circuit breaker comprises a plurality of poles (-). Each of the plurality of poles (-) comprises a first connection (-) and a second connection (-). Closing the particular pole (-) makes it possible to electrically connect the first connection (-) of the particular pole (-) to the second connection (-) of the particular pole (-) via the pole. In the method, a plurality of micro-ohm measurements are carried out at the plurality of poles (-), while the plurality of poles (-) are earthed on both sides in a P-P-P-E configuration. A contact resistance of one of the plurality of poles (-) is determined on the basis of the plurality of micro-ohm measurements.
