Siemens Industrial Controls 3RT2024-1AC20 Contactor
The Siemens 3RT2024-1AC20 is a high-performance 3-pole power contactor designed for reliable switching of inductive loads and motor control in industrial HVACR systems. Rated for 12A AC-3 at 400V and up to 25A AC-1 for resistive heating applications, this Sirius Innovation series device operates on a 24VAC 50/60Hz control circuit. Engineered for mechanical durability and long service life, it features screw terminals for secure electrical connections and supports DIN-rail mounting or screw-on installation. This size S0 contactor is fully compatible with modular system components, including auxiliary switches and thermal overload relays, ensuring seamless integration into existing motor starter assemblies. Its compact footprint and high switching frequency make it a standard choice for 12-amp contactor replacements where space and reliability are critical. With IP20 protection and optimized power consumption, the 3RT2024-1AC20 maintains system stability under rigorous duty cycles in commercial and industrial environments.
- Modular Design: Part of the Sirius Innovation system, allowing for easy expansion with side or top-mounted auxiliary contacts.
- High Switching Reliability: Specifically optimized for AC-3 motor starting and resistive loads up to 25A (AC-1).
- Robust Connection: Field-proven screw terminals ensure high-clamping force for consistent electrical conductivity.
- Environmental Resilience: Rated for operation in ambient temperatures up to 60°C without derating, ideal for enclosed control panels.
Common Questions:
What is the coil voltage for the 3RT2024-1AC20?
This model is equipped with a 24VAC coil compatible with standard 50Hz and 60Hz control transformers found in most HVACR systems.
Can this contactor replace older Sirius 3RT10 series models?
Yes, the 3RT20 series is the modern successor to 3RT10. While its dimensions are similar, always verify the frame size S0 and current ratings against your existing motor starter configuration.
Is this unit suitable for reversing starter applications?
Standard 3-pole contactors like this one can be utilized in reversing assemblies when paired with a second unit and the appropriate mechanical and electrical interlocking kits.
