Siemens Industrial Controls 3RT2046-1AC20 Contactor
The Siemens 3RT2046-1AC20 is a heavy-duty 3-pole power contactor designed for high-demand industrial motor control applications. Engineered for AC-3 switching, this S3 frame size unit handles motor loads up to 45 kW at 400V, making it a reliable choice for large-scale HVACR equipment and heavy machinery. It operates on a 24V AC 50/60Hz coil voltage, providing consistent actuation in control circuits. The integrated 1 NO + 1 NC auxiliary contacts allow for immediate status feedback or electrical interlocking without the need for additional add-on blocks. Built with screw-type terminals, this contactor ensures high contact reliability and stable electrical connections under vibration. It is fully compatible with the SIRIUS modular system, allowing for seamless integration with 3RU2 thermal or 3RB3 electronic overload relays. Techs appreciate the robust design and the ability to maintain peak performance in ambient temperatures up to 60°C.
Key Benefits for Technicians- SIRIUS S3 Compatibility: Directly compatible with the Siemens modular ecosystem for fast assembly and reduced downtime.
- High Power Density: Efficiently manages 95A AC-3 current ratings within a compact footprint to save enclosure space.
- Auxiliary Flexibility: Built-in 1NO and 1NC contacts simplify wiring for signaling and control logic.
- Global Approvals: Meets IEC 60947-4-1, UL, and CSA standards, ensuring compliance for diverse industrial installations.
- Long Mechanical Life: Designed for millions of switching cycles to withstand rigorous duty cycles in commercial and industrial settings.
What is the maximum horsepower rating for the Siemens 3RT2046-1AC20?
This contactor is rated for up to 75 HP at 460V/480V for 3-phase AC motor loads.
Can I use this contactor for non-inductive (AC-1) loads?
Yes, for AC-1 resistive loads, the 3RT2046-1AC20 supports a rated current of up to 130A, depending on localized cooling and terminal thermal limits.
Is the coil replaceable on the S3 frame contactors?
The S3 frame allows for field-replaceable coils and auxiliary front-mount or side-mount blocks to extend the utility of the device.
