The Schneider Electric Square D 8430DASV phase relay provides essential protection for three-phase electrical systems. Designed as a solid-state device, this relay actively monitors for critical faults including phase loss, voltage unbalance, phase reversal, and undervoltage conditions. Its primary function is to safeguard connected three-phase motors and associated equipment from damage caused by these electrical anomalies, ensuring operational integrity and longevity.

Technical Details

• Series: Square D 8430
• Type: Three-Phase Phase Relay
• Protection Functions: Phase Failure, Voltage Unbalance, Phase Reversal, Undervoltage
• Technology: Solid-State
• Voltage Monitoring: Detects deviations from nominal three-phase voltage levels.
