Newark offers phase monitoring relays that protect three-phase systems from phase loss, phase reversal and imbalance. These relays are designed to prevent motor damage and ensure stable operation.

Phase monitoring relays measure phase sequence, phase loss and voltage balance in three-phase systems. If any discrepancy is detected, the relay disconnects the load to prevent motor failure.

Key Features:

  • Phase loss and reversal protection for motors and equipment.
  • Adjustable voltage range for versatile use.
  • Compact design for easy installation in control panels.

Applications:

  • Industrial Motors – Ensure proper phase alignment and prevent damage.
  • HVAC Systems – Maintain stable operation in multi-phase compressors.
  • Renewable Energy – Monitor phase balance in solar and wind systems.
