elements
Different auxiliary switches can be attached (at the front or the side) to the
3RA1 reversing combination. An integrated auxiliary switch contact is avail-
able in frame size S00.
Accessories
The following accessories for the basic units can also be used for contactor
combinations for reversing:
• Auxiliary switch blocks (at the front/side)
• Surge suppressors
• Soldering pin adapters (frame size S00)
The following accessory is designed specifically for contactor combinations
for reversing:
• Locking devices for mechanical interlocking
• Locking devices for mechanical and electrical interlocking (at the front/
side)
• Terminals for contactor coils (for frame sizes S0 to S3)
• Mechanical connectors
• Wiring modules

contactor coils
To reach the coil terminals A1 and A2 of the contactor combinations for
reversing more easily from contactors of frame sizes S2 and S3, you can
use terminals for contactor coils.
For each combination, 2 x A1 and 1 x A2 are required.
Wiring module
Wiring modules are available to enable you to carry out different types of
wiring (Dahlander wiring, for example).
You can find out how to mount the wiring modules in the diagrams of the
self-assembly kits.
Mechanical
interlocking
Mechanical interlocking (for frame sizes S0 to S3) is available in 2 variants:
• Attachable at the front (contactor spacing: 0 mm)
• Attachable at the side (for frame sizes S0 to S3) with integrated NC con-
tact for electronic interlocking
Note
If you want NC contact interlocking, you must use contactors with 1 NC
contact in the basic unit with the 3RT1 contactors of frame size S00.
