3RA61/3RA62 compact starter
5.5 Connection
Mirror contact
With the aid of opening auxiliary contacts it is possible to implement a mirror contact query of
the main contacts. This requires the previously integrated auxiliary contact 21-22 (NC
contact) for compact starter 3RA61 or an external auxiliary switch block with at least one NC
contact (3RA6912-1A/3RA6913-1A and 3RA6912-2A/3RA6913-2A) for device variants
3RA62, 3RA64 and 3RA65.
Positively-driven
If the compact starter is designed to act as a direct starter for parallel wiring (3RA61), there
is positively driven operation in the basic device between auxiliary circuits 21-22 (normally
closed) and 13-14 (normally open). In addition, external auxiliary switch 3RA6913-1A or
3RA6913-2A provides positively driven contact elements with one NC contact and one NO
contact each.
