3-Phase Monitor
The MODEL 2581 3-Phase Monitor provides essential protection for industrial systems. This device detects critical conditions such as phase loss, low voltage, and phase reversal, safeguarding equipment from potential damage. Its encapsulated circuitry enhances durability, allowing operation in challenging environments. With a rapid 50ms response time, the monitor quickly identifies anomalies, enabling prompt system intervention. The unit's 240VAC nominal voltage and 218VAC trip point are precisely calibrated for reliable performance. A 5-year unconditional warranty underscores its robust design and manufacturing quality. This monitor is a practical component for maintaining operational continuity and equipment longevity.
