3-Phase Monitor
The Model 2581 3-Phase Monitor, SKU 2581-208, provides essential protection for industrial systems. It reliably detects phase loss, low voltage, and phase reversal, safeguarding critical equipment from potential damage. Operating at a nominal voltage of 208VAC with a precise 189VAC trip point and a ±2% tolerance, this unit ensures operational integrity. Its encapsulated circuitry enhances durability in demanding environments, resisting contaminants. The 50ms response time allows for rapid system intervention upon fault detection. Installation is streamlined with 1/4" quick-connect terminals. This monitor also features robust 2500 VRMS transient protection for 10ms and maintains a repeat accuracy of ±0.1%. An LED status indicator provides immediate operational feedback, contributing to efficient system management and reduced downtime. Its 10 million mechanical operations relay life ensures long-term reliability.
