3.4.1.1 Terminal markings of the contactors (frame sizes S00 to S3)
In contactors of frame size S00 with an integrated auxiliary contact, the ter-
minal marking complies with EN 50 012. This also applies to contactors of
frame sizes S0 to S3 with an attached auxiliary switch block (2 NO + 2 NC
contacts) that are available as complete systems.
Expanding the contac-
tors of frame size S00
All the contactors of frame size S00 (3 and 4-pole) can be expanded with
auxiliary switch blocks with the identification numbers 40 to 02 in acc. with
EN 50 005 as follows:
• Frame size S00 with an integrated auxiliary contact (identification number
10E or 01) for contactors with 3 or 5 auxiliary contacts
• Frame size S00 with 4 main contacts for contactors with 2 or 4 auxiliary
contacts
Note
The identification numbers on the auxiliary switch blocks only apply to the
attached auxiliary switches.
Expanding the contac-
tors with 1 integrated
NO contact, S00
(3RT101.-...01)
Contactors with one NO contact as an auxiliary contact with screw-type or
Cage Clamp terminals, identification number 10E, can be expanded with
auxiliary switch blocks with terminal markings in acc. with DIN EN 50 012
for contactors with 2, 4, and 5 auxiliary contacts. The terminal markings of
the complete contactors comply with EN 50 012. The identification numbers
11E, 22E, 23E, and 32E on the auxiliary switch blocks apply to the complete
contactors.
Important
Auxiliary switch blocks in acc. with EN 50 012 can only be combined with
contactors of frame size S00 that have 1 NO contact in the basic unit
because they are coded. These auxiliary switch blocks cannot be combined
with contactors that have an NC contact in the basic unit (identification num-
ber 01).
