Op.ct.
The information counts the number of disconnector
switching cycles. INS
Control
It is the task of the controls to execute command checks and establish communication between the command
source and the disconnector. Using the control settings, you specify how the commands are to be processed
(see also chapter
6.3.1 Command Checks and Switchgear Interlocking Protection ).
Through the function SBO (Select Before Operate, reservation 19 ), the switching device is reserved prior to the
actual switching operation, thus it remains locked for additional commands. Feedback monitoring provides
information about the initiator of the command while the command is in process, that means, informing
whether or not the command was implemented successfully. These two options can be selected individually in
the selection of the control model, so that 4 combinations in total are available (see the following table).
The control makes the following settings available (see next table).

Trigger Variants of the Disconnector
The activation types are identical to those for the circuit breaker. The meaning of abbreviations can be found
in
6.2.2.3 Connection Variants of the Circuit Breaker and 6.2.2.3 Connection Variants of the Circuit Breaker .
Whether the disconnector is triggered for 1-, 1.5-, or 2-phases depends on the design of the auxiliary and
control voltage system.
