Page 24: Positively Driven Contact Elements/Mirror Contacts
The 3RT1 / 3RT2 / 3RH2 contactors are suitable for applications in the safety circuit. For contactor relays, this applies on account of the positively driven operation of the contacts. For motor contactors, it applies on account of the mirror contact properties of the auxiliary contacts.

The hysteresis in the switching thresholds prevents the main contacts from chattering and thus prevents increased wear or welding when operated in weak, unstable networks.

After short-circuit disconnection, there must be no damage to the overload release or to any other part. The load feeder can resume operation without needing to be renewed. Welding of the contactor contacts only is permitted if these can be separated easily without significant deformation.
