Siemens 3RT2027-1AV60-0UA0 AC Power Contactor

Siemens 3RT2027-1AV60-0UA0 is a NEMA-version, 3-pole power contactor from the SIRIUS 3RT2 family designed for reliable motor control in industrial control panels. It handles up to 10 HP at 460/575 V and 60 Hz, with a three-pole main circuit and an auxiliary contact arrangement of 1 normally open and 1 normally closed contact, wired via screw terminals in the compact size S0. The unit is rated for an insulation voltage of 690 V and is specified for AC-3 duty, suitable for starting and stopping three-phase motors and other inductive loads. This combination of 3-pole main contacts, 1 NO + 1 NC auxiliary contact, and accessible screw terminals makes it straightforward to wire to standard relays and control logic in typical industrial applications, and the S0 footprint supports compact panel layouts in machine controls.
