A method for equalizing of Gesamtabbränden an electromagnetic switching device, and hereby corresponding electromagnetic switching device

An electromagnetic switching device (1) comprises a contact arrangement (2) having three contacts (3-5), the check-in a three-phase load (6) to the three phases (L1-L3) of a three-phase network, and (of the three phases L1-L3 ) decouple. Schaltabbrande occur at the contacts (3-5). For each contact (3-5) is determined a Gesamtabbrand (G1-G3) and a drive circuit (17) supplied. The contact assembly (2) of the drive circuit (17) operated in response to the Gesamtabbranden (G1-G3) such that the Gesamtabbrande (G1-G3) are approximately of the contacts (3-5) to each other.
