Available for order.

Thermistor Protection Relay RT-23 is an electronic device designed for continuous monitoring and protection of three-phase electric motors and generators against abnormal conditions. It ensures the disconnection of equipment in the event of hazardous situations such as winding overheating, phase loss, or a short circuit in temperature sensors.

⚙️ Key Functions of RT-23

  • Three-phase voltage presence monitoring: ensures correct phase sequence and detects phase loss.
  • Motor winding temperature control: supports connection of 3 or 6 thermistor (PTC) sensors for overheating monitoring.
  • Motor insulation integrity monitoring: detects insulation faults in windings.
  • Short-circuit detection in temperature sensors: protects against failures in the sensor circuit.
  • Automatic return to operating state: the relay automatically returns to normal operation after the fault is cleared.
  • Status indication: LED indicators show the current status of the relay and the presence of faults.
