Fanox ST / ST-D – Phase & Temperature Control Relay

The Fanox ST and ST-D relays combine three-phase voltage monitoring with PTC thermistor temperature monitoring in a single compact unit. Self-powered by the monitored voltage, they are designed for elevators with and without machine rooms, as well as general 3-phase equipment requiring combined phase and temperature protection.

  • Self-powered by the 3-phase monitored voltage
  • Phase monitoring: incorrect phase sequence and phase loss detection
  • PTC thermistor monitoring for temperature protection
  • Monitors PTC circuit for short-circuit and ruptured wire faults
  • Visual LED indication of trip cause
  • Compact DIN rail mounting
