282 Power Alerts // BFA Series
With nominal 3-phase line voltage applied, a flashing green NORMAL LED
gives positive indication of a good fuse and integrity of the wire connection
to each side of the fuse.1
A flashing red FAULT LED gives positive indication of an unconnected or
open fuse, or a BFA wiring fault that needs corrected such as a lost
connection to either side of the fuse or mismatched line and load wires.2
When phase loss occurs, both FAULT and NORMAL LEDS will extinguish.3
The BFA will continue to indicate the status of the fuse during a phase loss
if a regenerated voltage is produced on the open phase from a rotating
motor.4
