3-Phase Monitor
The MODEL 2522 B2522BM 3-Phase Monitor offers essential protection for industrial systems. This device monitors for phase loss, low voltage, and phase reversal, ensuring operational integrity. Its DPDT contact configuration provides versatile control options, while the manual reset type allows for deliberate system re-engagement after fault conditions. With a nominal voltage of 120VAC and an adjustment range of 85-120VAC, it adapts to various power requirements. A rapid response time of 0.05 seconds minimizes potential equipment damage. The monitor operates efficiently with a power consumption of 0.75W and maintains performance across an operating temperature range of -20° to +131° F. Its robust ABS plastic enclosure and 2500 VRMS transient protection contribute to its reliability in demanding environments. This unit is compatible with both Wye and Delta systems, simplifying integration without requiring a neutral connection.
