Status Indication
The Eagle has a conventional and reliable status
indicator semaphore which is directly linked to
the vacuum interrupter. The alternating material
color bands make the indicator cup highly visible
during the daytime as well as during the night.
An LED is provided for Lockout indication. Once
the recloser goes to lockout state, the LED flashes
periodically giving easily identifiable signal to the
utility crew investigating the fault.
Current Sensing
The Eagle uses a Rogowski coil CT for sensing the
load and fault currents. This provides a highly
accurate measurement for protection as well as
load profiling. Since it is not a conventional CT,
saturation is not a concern at the highest fault
current levels.
Mount Latching Mechanism
The Eagle has a latching mechanism on the H1
terminal that latches to the mounting clip. The
fuse clip and the latch ensure that the Eagle does
not drop open unless it is engaged at the H1
terminal ring.
