Siemens Industrial Controls 3RT2026-1AK60 Contactor
The Siemens 3RT2026-1AK60 is a heavy-duty SIRIUS size S0 power contactor engineered for reliable motor switching in demanding HVACR and industrial control panels. This 3-pole IEC contactor is rated for 25A (AC-3) at 400V, making it a standard choice for 11 kW motor starters and resistive load applications. Operating on a 120V AC 60Hz coil, it features integrated 1NO + 1NC auxiliary contacts to streamline control wiring and feedback loops. Built with screw terminals for secure electrical connections, this unit is designed for high switching frequency and extreme mechanical longevity. Whether you are replacing a failed magnetic contactor or building a new NEMA size 1 equivalent starter, the 3RT2 series provides the vibration resistance and thermal stability required for rooftop units and large-scale refrigeration compressors. Its compact 45mm width ensures efficient rail utilization in crowded enclosures.
Key Technical Benefits
- High Load Capacity: Rated for up to 25A (AC-3) or 40A (AC-1) to handle inductive motor starts and heating elements.
- Integrated Auxiliaries: Factory-installed 1NO/1NC contacts eliminate the need for additional add-on blocks in basic interlocking circuits.
- SIRIUS Modular System: Full compatibility with 3RU21 thermal overload relays and 3RV2 motor starter protectors for a complete protection suite.
- Broad Climate Range: Tested for reliable operation in ambient temperatures ranging from -25 to +60 degrees Celsius.
- Enhanced Durability: Mechanical service life of up to 10 million switching cycles for reduced maintenance intervals.
Common Installation Questions
What is the maximum horsepower rating for this contactor at 460V?
The 3RT2026-1AK60 is typically rated for 15 HP at 460V and 20 HP at 575V for standard three-phase motor applications.
Can I use this contactor for 50Hz electrical systems?
While the coil is optimized for 120V 60Hz, Siemens SIRIUS coils are often dual-rated; however, you should verify the specific voltage tolerance if operating on a 110V 50Hz grid to prevent coil chatter or overheating.
Is this unit compatible with 3RT1 series footprints?
The 3RT2 series is the direct successor to the 3RT1. While dimensions are similar, always verify the depth and mounting hole alignment when retrofitting older control plates.
