Siemens 3RT2027-1AK60-0UA0 Three-Phase Contactor

Siemens Sirius 3RT2027-1AK60-0UA0 is a three-pole power contactor rated for 32 A and 10 HP at 460/575 V, designed for switching three‑phase motors in industrial control circuits. The coil voltage is 110 V AC for 50 Hz operation (and 120 V AC for 60 Hz operation), with a coil power of 2.7 W in the S0 size, and it includes one auxiliary contact (1 NO + 1 NC) with screw-terminal connections. This NEMA‑version contactor belongs to the 3RT2 family and is suitable for standard motor‑start applications such as conveyors, pumps, and fans in 50/60 Hz environments. The high-voltage circuit rating on the main contacts is 460/575 V, and the unit’s 3‑pole configuration supports straightforward wiring in control panels. Its compact S0 form factor and integrated auxiliary contact enable reliable, space‑efficient motor control in industrial equipment without requiring additional relays.
