Auxiliary switch blocks for 3RT1 power contactors
9.3.2.1
Size S6 to S12 contactors feature a laterally mounted auxiliary switch fitted at the factory.
The auxiliary switches are available with screw-type or spring-loaded connection system in
the following versions:
● On the front 1-pole to 4-pole
● Lateral, 2-pole
Optionally, auxiliary switches with connection from above or below are available. These
auxiliary switch blocks have fixed location identifiers and are supplied with screw
connections only. For spring-loaded connection, 4-pole auxiliary switch blocks are offered
that are only fitted with auxiliary contacts 1 and 2.
2-pole auxiliary switches can be mounted on the side in addition to the auxiliary switches
already mounted at the factory. If 1-pole auxiliary switch blocks are used, the location
identifiers on the contactor must be noted when making a selection for ordering.
