Siemens Industrial Controls 3RT2027-1AC20 Contactor
The Siemens 3RT2027-1AC20 is a heavy-duty, industrial-grade power contactor designed for high-cycle motor switching applications. Engineered within the SIRIUS Innovations family, this Size S0 contactor delivers reliable performance for AC-3 inductive loads up to 32A and 15 kW at 400V. This 3-pole unit operates on a standard 24V AC 50/60 Hz control coil, making it a staple for HVACR control circuits and industrial automation panels requiring finger-safe screw terminal connections. With 1 NO (Normally Open) and 1 NC (Normally Closed) integrated auxiliary contacts, it provides immediate feedback logic without needing extra blocks, though it is fully expandable for complex signaling requirements. Whether you are performing a Direct On Line (DOL) motor start or replacing an older 3RT1034-1AC20 model, this unit ensures high contact stability and mechanical durability exceeding 10 million cycles. The rugged IP20-rated enclosure is designed for 35mm DIN rail or surface mounting, facilitating a quick retrofit into existing control cabinets.
Key Benefits:- High Current Capacity: Rated for 32A (AC-3) and up to 50A (AC-1) to handle demanding resistive and inductive loads.
- Integrated Logic: Built-in 1NO + 1NC auxiliary contacts eliminate the need for additional add-on blocks for basic interlocking.
- Versatile Mounting: Standard S0 frame size supports rapid DIN rail installation or secure surface mounting in any orientation.
- Global Standards: Fully compliant with IEC 60947, UL, and CSA specifications for use in international electrical assemblies.
- What is the maximum horsepower rating for this contactor? At 460V, the 3RT2027-1AC20 is rated for up to 20 HP, and 25 HP at 575V for 3-phase commercial motors.
- Can I add more auxiliary circuits to this unit? Yes, the S0 frame allows for front-mounted or side-mounted auxiliary switch blocks to expand up to 4 additional contacts.
- What is the compatible overload relay for motor protection? This contactor is designed for direct mounting with the 3RU21 thermal overload or 3RB30 electronic overload relays.
