It is rated for AC-3 switching up to 690 V and carries a DC-13 rating of 0.3 A at 220 V for inductive DC loads. The IP20 rating on the front and on the terminals means the contactor is finger-safe when installed in an enclosure — no additional shrouding needed for routine panel access. The AC-3 operational current is specified at three voltage points: 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. These are the motor-switching currents the contactor can handle under typical induction-motor starting conditions (make and break under load). The maximum switching rate is 800 operations per hour in AC-3 and 250 in AC-4 — the lower AC-4 limit reflects the harsher plugging/reversing duty. Coil consumption is 0.82 W during pick-up and 0.24 W holding — low enough to daisy-chain multiple contactors on a single 24 VDC supply without exceeding the power budget of a typical PLC output card. The control supply voltage type is AC, so verify the coil voltage variant before wiring.","metaTitle":"Siemens 3RT7027-1AV00 S0 Contactor, 3-Pole, 690V AC-3, 45mm","metaDescription":"Siemens 3RT7027-1AV00 S0 contactor, 3-pole, 690V AC-3 rated, 45mm wide, IP20 terminals, screw and snap-on DIN rail mount.
