Model 2644 3-Phase Monitor
The Model 2644 3-Phase Monitor provides essential protection for industrial systems. Operating at 380VAC with a 50Hz frequency, this device detects critical conditions including phase loss, low voltage, and phase reversal. Its restart delay feature, approximately 3.5 minutes, ensures controlled system recovery after a fault. Users can adjust the response time from 0.2 to 20 seconds, allowing for application-specific tuning to prevent nuisance tripping. The monitor features DPDT 10 amp output contacts at 240VAC resistive, ensuring reliable switching for control circuits. With a robust design, including an ABS plastic enclosure and a 5-year unconditional warranty, the Model 2644 offers consistent performance across an operating temperature range of -20° to +131° F. UL Recognized and CSA Certified, it meets stringent industry standards for dependable operation in diverse environments, minimizing downtime.
