Model 2644 3-Phase Monitor
The Model 2644 3-Phase Monitor provides essential protection for industrial systems. It reliably detects critical conditions including phase loss, low voltage, and phase reversal, safeguarding equipment from operational disruptions. With a nominal AC voltage of 120VAC (phase to phase) and an adjustment range of 85-120V, it adapts to specific system requirements. The unit features a manual reset type and DPDT 10 amp output contacts for robust control. Its 5-year unconditional warranty and expected relay life of 10 million mechanical operations underscore its durability and long-term reliability. Operating effectively from -20° to +131° F with 0-97% humidity tolerance, this monitor maintains performance in diverse industrial environments. Its transient protection of 2500 VRMS for 10ms further enhances system integrity, ensuring consistent and secure operation.
