Siemens SIRIUS 3RN2 Thermistor Motor Protection Relays

Siemens SIRIUS 3RN2 Thermistor Motor Protection Relays

SIRIUS 3RN2 thermistor motor protection relays evaluate PTC sensors in the motor winding for direct motor temperature protection.

Key features

  • Compact and standard evaluation units, also suitable for bimetallic switches
  • Open-circuit and short-circuit detection in the sensor circuit
  • ATEX-approved versions for motors in hazardous areas
  • Non-volatile fault storage and protective separation up to 300 V (3RN2013/3RN2023)
  • 3RN2023 with 2 sensor circuits for warning and disconnection
  • Control supply 24 V AC/DC or 24-240 V AC/DC
