Coupling contactor recommendation:
XOLTA is recommending using motorized circuit breakers (cou-
pling contactors) for all C&I installations with auxiliary switch
(feedback). Follow the local country grid code/grid operator
rules for selection of the coupling contactor.
The maximum AC currents of the single Xolta racks are as
presented in Table 3.
Connection schematics:
Figure 1 presents Xolta C&I installation with NA Schutz and
coupling switch.
For detailed information about ABB and Ziehl connection refer
to device manuals.
Refer to the document “Schaltungsempfehlungen NA-Schutz
und Kuppelschalter” for the list of recommended motors and
coupling contactors for different power levels.
There is also wide range family of the coupling contactors
from Eaton:
