IEC Magnetic Contactor for Motor Switching
This SIEMENS 3RT2027-1AK60 contactor is a three-pole IEC magnetic starter rated for 32 A inductive and 50 A resistive loads. It operates on a 110/120V AC coil and includes one normally open and one normally closed auxiliary contact. The unit belongs to the SIRIUS 3RT20 series in frame size S0.
Suited for DIN Rail Panels Without Enclosure
This contactor suits control panels that use DIN rail or surface mounting and accept screw-terminal wiring. It is not for applications requiring a built-in NEMA-rated enclosure, reversing capability, or coil voltages outside the 110/120V AC range. Buyers needing integrated overload protection or different auxiliary contact counts should look elsewhere.
Verify Coil Voltage and Mounting Space
Before ordering, confirm your control circuit supplies 110V or 120V AC to match the coil rating. Check that the panel provides at least 3.55 in height and 2.15 in width for the overall dimensions. Ensure the terminal blocks accept screw connections and that the 32 A inductive rating meets your motor load requirements.

Questions about this item
What coil voltage must my control circuit supply for the 3RT2027-1AK60 contactor to operate?
The contactor coil is rated for 110/120 V AC, so your control circuit must provide voltage within that range for reliable pickup and hold-in.
Can the three main poles of this S0 frame contactor switch the same 32 A inductive load that my existing motor draws?
Yes, each pole is rated for 32 A full-load inductive current (AC-3) and 50 A resistive, matching typical motor loads up to that level.
How can I verify the contactor is functioning correctly after wiring it to the DIN rail?
Apply 110/120 V AC to the coil terminals; the three main poles should close and the 1NO auxiliary contact should show continuity while the 1NC opens.
