Siemens Industrial Controls 3RT2023-1AC20 Contactor
The Siemens SIRIUS 3RT2023-1AC20 is a high-performance 3-pole IEC contactor engineered for heavy-duty motor control and switching applications. This Size S0 contactor features a 9 Amp rated operational current (AC-3 at 400V) and a dependable 24V AC 50/60Hz coil, making it a critical component for 3-phase systems up to 4 kW. Designed for industrial-grade durability, the 3RT2023-1AC20 incorporates a 1 NO + 1 NC auxiliary contact configuration to facilitate advanced signaling and interlocking logic. With its standard screw terminal connections and 35mm DIN rail mounting capability, this unit provides a direct physical and electrical replacement for the legacy 3RT1023-1AC20. The magnetic contactor is built to withstand rigorous HVACR environments, operating efficiently in temperatures ranging from -25 to +60 °C, ensuring stable performance in climate-controlled and industrial enclosures.
Key Benefits
- Optimized Motor Control: Rated for 3 HP at 230V and 5 HP at 460V, providing reliable Direct On Line (DOL) starting for 3-phase motors.
- Integrated Versatility: Equipped with built-in 1 NO + 1 NC auxiliary contacts to eliminate the need for additional add-on blocks in basic control circuits.
- Space-Efficient Design: The compact Size S0 frame allows for high-density mounting on standard 35mm DIN rails within control panels.
- Broad Compatibility: Fully compatible with the SIRIUS innovation line of accessories, including thermal and solid-state overload relays.
- Rugged Electrical Life: Engineered for approximately 10 million mechanical switching cycles to minimize downtime in high-frequency applications.
Common Questions
Is the 3RT2023-1AC20 a direct replacement for the older 3RT10 series?
Yes, the 3RT2023-1AC20 serves as the modern replacement for the 3RT1023-1AC20. While dimensions and electrical ratings are compatible, note that some direct-mount accessories from the older series may require upgrading to the SIRIUS innovation equivalents.
Can I use this contactor with a 24V DC control signal?
No, this specific model is designed with an AC operating coil rated for 24V 50/60Hz. Supplying 24V DC will result in coil failure or improper actuation. Always verify the coil voltage (Us) matches your control circuit requirements.
Does this unit include surge suppression for the coil?
This standard version uses screw terminals and does not have an integrated varistor or RC element. For protection against voltage spikes, we recommend installing a clip-on surge suppressor from the 3RT2926 series.
