Monitor for 3-phase Type PSSW1

Monitor for 3-phase, Phase Asymmetry, Phase Sequence, Over- and Undervoltage

Monitor for 3-phase Type PSSW1

Part number

AC 230 V
AC 400 V

Product description

 

Relays for 3-phase networks type PSSW1 monitor 3-phase networks for phase-sequence, asymmetry and over- and undervoltage.

Applications
Monitoring of 3-phase-networks at heat pumps, compressors or at machines at building sites.

Functions

  • Over- and undervoltage, adjustable ± 2-20 % (common)
  • Asymmetry adjustable 5-15%
  • Phase loss
  • Phase sequence
  • Switching delay adjustable 0,1-12 s (for voltage and asymmetry)
  • Bifrequential measuring input 50/60 Hz

Displays (4 LEDs for)

  • Over-/undervoltage
  • Asymmetry
  • Phase-sequence/loss
  • State of relay
