Fuse Status Indicator

The Model BFA Fuse Status Indicator shows normal or open fuse and also reports connection integrity. With a nominal 3-phase line voltage applied, the BFA Fuse Status Indicator flashes a normal LED green light that gives positive indication of a good fuse and integrity of the wire connection to each side of the fuse. The indicator flashes a red fault LED when a fuse is unconnected or open, if there is a lost connection to either side of the fuse, and if mismatched line or load wires are present. When phase loss occurs both fault and normal LED's will extinguish. The BFA indicator 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. The BFA Fuse Status Indicator mounts externally to a panel and can be mounted vertically or horizontally. It can be used for all UL Fuses Class H, J, K, R, RK. It can be viewed from a distance and has a universal input of 208-600 VAC.
