Auxiliary switch blocks - for example, 3RH1911-1GA22 (2 NO + 2 NC con-
tacts) in acc. with EN 50 011 - can only be attached to auxiliary contactors
with 4 NO contacts (3RH1140-..... ) because they are coded. The identifica-
tion number (62E) printed on the auxiliary switch block (6 NO + 2 NC con-
tacts) applies to the whole contactor.
NO and NC contacts are in the same position on all the auxiliary contactors
with the identification number 62E (DIN EN 50 011).
This means contactors can be replaced without changing the wiring, which
therefore makes wiring very easy. You can attach auxiliary switch blocks that
comply with EN 50 005 on all 3RH11 auxiliary contactors and 3RT101 motor
contactors. For example, the 3RH1911-1FA22 auxiliary switch block (2 NO +
2 NC contacts) has the identification number 22, and this only applies to the
attached auxiliary switch block.
Below are some examples of graphical symbols for auxiliary contactors with
the identification letter E that comply with EN 50 011:
