The breaker interlocking element contains the auxiliary logic for interlocking of circuit
breakers. Up to three inputs can be assigned for interlocking the open and close controls.
An input is also available for supervision by a synchrocheck element. The breaker can also
be tagged through the front panel interface or through SCADA. Opening and closing of a
tagged device is inhibited in logic.
