3-Phase Monitor
The B2522B 3-Phase Monitor offers essential protection for industrial systems. This device safeguards equipment by continuously monitoring for phase loss, low voltage, and phase reversal, preventing potential damage and operational downtime. Its automatic reset functionality ensures seamless system recovery without manual intervention. With a DPDT contact configuration and a rapid 0.05-second response time, it provides reliable and swift detection of anomalies. The monitor operates efficiently across a 85-120VAC adjustment range and is compatible with both Wye and Delta systems, offering versatile integration. Its robust design, featuring an ABS plastic enclosure and a wide operating temperature range of -20° to +131° F, ensures durability in demanding environments. This unit contributes to maintaining consistent operational integrity.
