BE-ELC-0000461 SF1 Phase Failure/Sequence Relay - 525V.

Phase Failure / Phase Sequence Monitor

The Electro 11-pin plug-in range of control and timing devices are to be installed into a standard 11-pin base making installation easy and convenient.

The SF1 Monitors negative phase sequence (NPS) voltage to detect phase failure, phase reversal, and phase imbalance. The NPS voltage of the unit is fixed at 7%. When any of these faults occur the unit will de-energize. The relay will only re-energize if the supply voltage corrects itself. The unit will not react to a balanced voltage variation.

Features:

  • Relay ON LED
  • Output 10A SPDT
  • Detection of phase asymmetry
  • Insensitive to regenerated EMF
  • Fast response to reverse phase sequence
  • Monitoring relay for 3-phase voltage control
  • Measures if all 3 phases are present and in sequence
  • Insusceptible to balanced supply voltage variation
