For maximum breaker diagnostics use both 52A and 52B contacts.
Some diagnostics are not available if only one of the two is used.
A relay failure alarm should provide immediate attention as circuit
is no longer protected. Relay failure output is normally energized.
FP-4000 can initiate a breaker close via the front panel interface
and/or remote activation through communication or discrete input.
Residual connection may be used in place of zero sequence CT.
Delta or open delta PT connection may be used in place of wye-ground connection.
