RS PRO Phase Monitoring Relays


RS PRO is proud to present a complete range of phase monitoring relays designed for 3 phase systems. Each monitor relay is packed with excellent features to ensure effective protection against all types of low voltage faults. These compact high-quality monitoring devices offer over-voltage and under-voltage protection, protect against voltage phase sequence, phase loss, and phase asymmetry.

Key Features


  • Phase Failure Relays

  • Compatible with 3 or 4 wire application

  • Switchable by a dip switch

  • Selectable supply voltage

  • Adjustable under and over voltage set points

  • Selectable ON/OFF time delays

  • LED Indication

  • Compact housing

Specifications


  • Compact width: 17.5 mm

  • Multi-Voltage: Three Phase 3 Wire @ 208-480

  • VAC or Three Phase 4 Wire @ 120-277 VAC

  • Can be configured for 3 Phase 3 Wire or 3 Phase 4 Wire system

  • Protection against Phase loss, Phase Sequence, Phase Asymmetry, Under Voltage & Over Voltage

  • Selectable Under Voltage / Over Voltage, Asymmetry and Phase Sequence

  • LED Indication for all Faults & for change in dip switch settings during runtime for better security Adjustable ON/OFF Time Delay in seconds minutes

  • 1 C/O Configuration

Connection


  • Connection for supply voltage and relay is illustrated on the side of the device.
