Features

• Full-featured voltage/phase monitoring relays

• Undervoltage, overvoltage, phase imbalance, phase loss (single-phasing), phase reversal

• Universal voltage range of the 208-480V provides the flexibility to cover a variety of applications; 120V and 600V units also available

• Automatic or manual reset after the fault condition is corrected

• User-adjustable settings include nominal voltage, percent phase imbalance, undervoltage drop-out, time delay on undervoltage and time delay on restart after fault

Features
