The 55 mm width and 91 mm depth fit standard 35 mm DIN rail (DIN EN 50022) enclosures, with screw-and-snap mounting and +/-180° rotation flexibility on vertical surfaces. Rated operational current at DC-13 for 220 V is 0.3 A, so it handles solenoid or brake loads at that voltage. The S0 frame leaves room for side-by-side mounting without derating when ambient stays within -10 to +55 °C. Screw-type terminals on both main and auxiliary circuits accept 2x (0.5...1.5 mm²) solid or 2x (0.75...2.5 mm²) finely stranded with ferrules. The product accepts auxiliary switch add-ons (product extension auxiliary switch: yes), so you can add NC/NO blocks without changing the base contactor.","metaTitle":"Siemens 3RT7027-1AM05 SIRIUS Contactor, 3-Pole, 690V AC-3, 5","metaDescription":"Siemens 3RT7027-1AM05 SIRIUS contactor, frame size S0, 3-pole, 690V AC-3 max, 55mm width, IP20.
