SW31K-AC690V - Voltage Monitor for 3-phase Networks - S222271

  • S222271
  • Product Type IP00 motor, IP20 electronics
  • Supply voltage AC 230 V
  • Execution Motor IP44, electronics IP20 / depending on mounting and position
  • Output function Outputs/Relays
  • Measured value Pressed, painted steel sheet, sprayed with PP plastic

Undervoltage monitor for threephase networks without N for monitoring on voltage failure. The voltage is being measured between phases and an artificial neutral point. At symmetrical decrease of the voltage to approx. 50% of the nominal value or in case of failure of a phase the integrated relay (1 change-over contact) releases with a delay ofapprox. 1s. With engines running on 2 phases, so much back voltage can be produced that the failure of a phase may be not detected. The SW31K is available for measuring voltages AC 400 V and AC 690 V. As supply voltage in the standard version AC 230 V is needed.

Application

  • Monitoring of three-phase networks on loss of a phase
  • monitoring of fuses
