It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with mounting-position flexibility of +/-180° rotation and +/-22.5° tilt on a vertical surface. The built-in auxiliary switch carries a rated operational current of 10 A at 24 V, 6 A at 60 V, and 6 A at 230 V — all AC values. At 400 V it drops to 3 A, and at 500 V to 2 A. For DC circuits, the auxiliary contacts are rated 2 A at 48 V, 1 A at 110 V, and 0.9 A at 125 V. These are the contact ratings for the auxiliary circuit, not the main poles; use them to size your control-loop loads (PLC inputs, pilot lights, relay coils) without exceeding the contact's switching capacity at the applied voltage. ## Panel integration and clearances The contactor envelope is 96 mm wide, 140 mm high, and 152 mm deep — a Size S3 footprint that occupies roughly one-third of a standard 600 mm wide enclosure bay.","metaTitle":"Siemens 3RT2346-1AG20 SIRIUS Contactor, Size S3, 110 VAC Coi","metaDescription":"Siemens 3RT2346-1AG20 SIRIUS contactor, Size S3 frame, 110 VAC 50/60 Hz coil.
