Siemens Industrial Controls 3RT2026-1AG20 Contactor
The Siemens 3RT2026-1AG20 is a heavy-duty SIRIUS Innovation Size S0 magnetic contactor engineered for reliable motor switching in demanding HVACR and industrial automation environments. This 3-pole AC-3 contactor is rated for 25 Amps and 11 kW at 400V, featuring a 110V AC coil (50Hz) / 120V AC coil (60Hz) to integrate seamlessly with standard control circuits. Designed for high switching frequency and electrical endurance, it utilizes screw-type terminals for secure, vibration-resistant power circuit connections. The unit includes 1 NO + 1 NC integrated auxiliary contacts, allowing for immediate status feedback and interlocking without additional modules. Its compact 45mm frame width maximizes panel space, while the IP20 protection rating ensures safe handling during maintenance. High short-circuit current ratings (SCCR) and climate-resistant construction make this SIRIUS 3RT2 series contactor a technical standard for contractors requiring modularity and long-term durability in IEC motor starter applications.
Key Benefits for Technicians:- S0 Frame Compatibility: Fits standard 35mm DIN rails and integrates with the full SIRIUS modular system, including thermal overload relays and function modules.
- High Amperage Rating: Supports 25A inductive loads, making it ideal for managing compressors and large blower motors in HVAC systems.
- Integrated Auxiliaries: Features 1NO / 1NC built-in contacts, reducing the need for add-on blocks and simplifying wiring diagrams.
- Rugged Electrical Life: Designed for millions of switching cycles under load, ensuring minimal downtime in high-cycle industrial environments.
What is the maximum horsepower rating for this contactor?
At 460V, the 3RT2026-1AG20 is rated for approximately 15 HP, providing robust performance for three-phase motor control tasks.
Can I use this for 24V control circuits?
No, this specific model is equipped with a 120V AC coil. Using a 24V signal will fail to pull in the armature; ensure your control transformer output matches the 110/120V rating.
Does this unit support side-mounting auxiliary blocks?
Yes, the SIRIUS S0 frame allows for both front-mounted and side-mounted auxiliary contact blocks to expand your circuit logic as needed.
