3 3RT, 3TB, 3TF Contactors for Switching Motors 3RT10 contactors, 3-pole, 3 ... 250 kW 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 indicator (RLT) - Signal through free input, e. g. overload relay tripped.

No. 32E, 23E, 22E, 11E NSB0_00450b Size S00 contactors have an auxiliary contact integrated in the basic unit. Contactors with a NO contact as auxiliary contact with screw or Cage Clamp terminals, identification number 10E, can be expanded into contactors with 2, 4 and 5 auxiliary contacts according to EN 50012 using auxiliary switch blocks. The identification numbers 11E, 22E, 23E and 32E on the auxiliary switch blocks apply to the complete contactors. These auxiliary switch blocks cannot be combined with contactors which have a NC contact in the basic unit (identification number 01) as they are coded. All contactors of size S00 with one auxiliary contact (identification numbers 10E or 01) and the contactors with 4 main contacts can be expanded into contactors with 3 or 5 auxiliary contacts using auxiliary switch blocks with the identification numbers 40 to 02 (in the case of contactors with 4 main contacts: 2 or 4 auxiliary contacts) according to EN 50005. The identification numbers on the auxiliary switch blocks apply only to the attached auxiliary switches. Single- or two-pole auxiliary switch blocks with connection options from above or below enable easy and clearly arranged wiring especially for the installation of network access junctions. These auxiliary switch blocks are offered only with screw terminals. 3RT, 3TB, 3TF Contactors for Switching Motors Ident. No. 01 Aux. switch blocks, EN 50005, 4 or 2 contacts Ident.

They are suitable in particular for switching small voltages and currents (hard gold-plated contacts) and for operation in dusty atmospheres. The NC auxiliary contacts are not mirror contacts. All the previously mentioned auxiliary switch variants can be snap-fitted onto the front of the contactor. The auxiliary switch block has a centrally positioned release lever for disassembly.
