Zusammenfassung: | The present invention generally relates to a switching method for an electromagnetic switching device. In particular, it may relate to a switching method for a contactor, having at least one load contact which has a current carrying capacity,
The aim of the invention is to protect an electromagnet switching device when a load is switched to a supply voltage. A current that flows through the load contact is monitored. The electric circuit is interrupted when the current exceeds a threshold value that is below the current carrying capacity of the load contact. The electric circuit is automatically closed again after the current which flows through the load contact has decreased. |
