Marsh Bellofram Diversified Electronics Division BFA Series Fuse Status Indicator - 1

BFA Series Diversified Electronics atcdiversified.com 800.727.5646 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 1 2 3 4 BFA-SERIES Troubleshooting Guide F u s e S t a t u s In d i c a t o r \\\OPERATION \\\DIMENSIONS (INCHES) \\\SPECIFICATIONS NOMINAL VOLTAGE 208-600 VAC, ±10%, Phase-to-Phase, 50/60 Hz MAX.

800.727.5646 atcdiversified.com Diversified Electronics BFA Series Power Alerts // BFA Series 283 CAUTION: The BFA should not be confused with ATC Diversified Electronics 3-Phase Voltage Detectors. The BFA is designed to detect blown fuses and not voltage potentials from Phase-to-Ground or Phase-to-Phase in the 40 VAC range and up. It should be understood that dangerous voltage potentials can still exist within the panel even though the BFA has no LEDs flashing. For voltage detection see The ATC Diversified UPA Series Power Alerts. A. Normal, fuse good, electrical contact across fuse A....
