3-Phase Monitor
The Model 2642 3-Phase Monitor provides essential protection for industrial equipment operating on 575VAC systems. This device detects critical conditions including phase loss, low voltage, and phase reversal, safeguarding machinery from potential damage. Its adjustable trip delay and response time, ranging from 0.2 to 10 seconds, allow for precise system integration and tailored protection. Users can select between automatic or manual reset types, enhancing operational flexibility to suit specific application requirements. With robust DPDT output contacts rated at 10 amps at 240VAC resistive, the monitor ensures reliable control and signaling. Transient protection of 2500 VRMS for 10ms further enhances its durability against electrical disturbances. Engineered for consistent performance, this unit maintains a repeat accuracy of ±0.5% of setpoint under fixed conditions, ensuring dependable monitoring in demanding industrial environments.
