Model 2644 3-Phase Monitor
The Model 2644 3-Phase Monitor offers essential protection for industrial electrical systems. Operating at 208/240VAC, it features an adjustable voltage range of 160-240V and a configurable response time from 0.2 to 20 seconds. This device reliably detects critical conditions such as phase loss, low voltage, and phase reversal, preventing equipment damage and operational downtime. Its DPDT 10 amp output contacts at 240VAC resistive ensure robust control. With a 5-year unconditional warranty and UL Recognized/CSA Certified approvals, the Model 2644 provides consistent performance and long-term reliability in demanding environments. Its auto-reset function simplifies maintenance, reducing intervention needs. The unit's transient protection of 2500 VRMS for 10ms enhances durability. Operating across a -20° to +131° F temperature range, it maintains functionality in varied conditions.
