The disconnect switch element contains the auxiliary logic for status and serves as the interface for opening and closing of
disconnect switches from SCADA or through the front panel interface. The disconnect switch element can be used to cre-
ate an interlocking functionality. For greater security in determination of the switch pole position, both the 52/a and 52/b
auxiliary contacts are used with reporting of the discrepancy between them. The number of available disconnect switches
depends on the number of the CT/VT modules ordered with the L90.
•
