3RT, 3TB, 3TF Contactors for Switching Motors
Control circuit:
• Contactor control through AS-Interface by way of terminals
AS-i +/AS-i –. Each of these terminals is jumpered and
connected twice to a 4-pole connector which is separate from
the other control inputs.
Advantages:
- The AS-Interface cable is not interrupted if the connector is
pulled out
- The contactor remains functional through the local control
inputs and its own 6-pole connector
• Control signals through AS-i:
- Contactor ON/OFF
• Status signals through AS-i:
- Contactor ON/OFF
- Automatic/Local control:
- Remaining lifetime (RLT)
- Signal through free input, e.g. overload relay tripped.

S2 Local control option
Possibility of switching from automatic control to local control by
means of terminals H1/H2/H3, i.e. automatic control through
AS-Interface can be deactivated e.g. during startup or in the
event of a fault and the contactor can be controlled manually.
