Features of Selec Motor Protection Relay

  • Phase loss, phase imbalance, phase sequence, overload trip current, and under/over current are among the monitors.
  • Fits either a 1Ø or a 3Ø motor.
  • Preciseness: 5% of zero.
  • Two C/O output relays (DPDT).
  • Remote/auto testing is possible.
  • 230V AC ± 15% is the aux supply. Alternatively, 415V AC ±15%

Application of Selec Motor Protection Relay

  • Control and safety of motors for different types of drives
  • Application-specific standard configurations that reduce the amount of time needed to set up and commission relays
  • preconfigured systems for industrial and utility distribution
