Model 2644 3-Phase Monitor
The Model 2644 3-Phase Monitor provides essential protection for industrial systems. It reliably detects critical anomalies including phase loss, low voltage, and phase reversal, safeguarding equipment from potential damage. Operating at 208/240VAC with an adjustable range of 160-240V, this unit offers precise monitoring capabilities. Its adjustable response time, from 0.2 to 20 seconds, allows for application-specific configuration to prevent nuisance tripping or ensure rapid shutdown. The DPDT 10 amp output contacts ensure robust control integration. With a 5-year unconditional warranty and a mechanical relay life of 10 million operations, the Model 2644 delivers sustained performance in demanding environments. It maintains functionality across a -20° to +131° F operating temperature range and tolerates 0-97% humidity without condensation, ensuring operational continuity and system integrity.
