SYSTEM SETUP
5
The breaker control element contains the auxiliary logic for status and serves as the interface for opening and closing of a
circuit breaker from protection, autoreclose, SCADA, or through the front panel interface. The breaker control element can
be used to create interlocking functionality. For greater security in determination of the breaker position, both the 52/a and
52/b auxiliary contacts are used with reporting of the discrepancy between them.
To use this element, configure the contact outputs that trip and close the breaker to use FlexLogic operands
(or

element inputs as described here.
A description of the operation of the breaker control and status monitoring features from the front panel is provided in
chapter 4.
There are two breaker control elements for each CT/VT module installed. The following settings are available for each
breaker control element.
