3-Phase Monitor
The MODEL 2581 3-Phase Monitor, SKU 2581-480, provides essential protection for industrial systems. Operating at a nominal 480VAC, it precisely detects phase loss, low voltage, and phase reversal. Its encapsulated circuitry enhances durability, ensuring reliable performance in demanding environments. With a rapid 50ms response time, this monitor quickly identifies anomalies, preventing potential equipment damage. Power consumption is efficient at 4.5W. The unit features a 436VAC trip point with a tight ±2% tolerance, maintaining system integrity. Its 1/4" quick-connect terminals facilitate straightforward installation. This device offers consistent monitoring for critical three-phase applications, operating reliably from -20° to +131° F with 97% humidity tolerance. A 10 million mechanical operation relay life further underscores its robust design, ensuring long-term operational stability.
