Modes of Operation
Eagle can be configured to operate as a simple
single-phase breaker, sectionalizer or a recloser. A
single configuration can be used in multiple
applications at various levels of a feeder.
Breaker Recloser
Cold Load Pickup and 2 Harmonic Inrush
nd
Restraint
Depending on the protection philosophy, a
simpler cold load pickup can be set up or a more
sophisticated 2 harmonic inrush blocking can be
nd
configured to avoid nuisance tripping from load
picking up after a sustained outage.

Adaptive Non-Reclose and Hot Line Tag Modes
Toggling the "non-reclose" handle triggers the
recloser into non-reclose / hot ling tag mode. By
default, Eagle enters the non-reclose mode when
the NR handle is engaged. It uses the fastest
available tripping curve to trip and then stops
auto-reclosing. Alternatively, if hot line tag
settings are enabled, the recloser enters hot line
tag mode when the NR handle is engaged. The
protection can be made more sensitive using the
pickup and time multiplier settings. The NR
handle is clearly visible from ground level when
Sectionalizer
engaged.
