The screw terminals on the S3 frame accept standard lug or ring terminations, and the built-in auxiliary contact block (1 NO + 1 NC) gives you one feedback signal for the PLC and one for a status lamp or interlock without adding a side-mount module. RoHS compliance is confirmed since 01-09-17, and REACH Article 33 candidate-list information is available on request. The S3 frame footprint (146 x 136 x 177 mm packaged) mounts on standard DIN rail or panel plate. The 4-pole configuration means it occupies the width of a standard S3 contactor — about 55 mm on the rail — leaving room alongside for overload relays or busbar systems. The 110 V AC coil draws inrush current at pickup; verify your control transformer is sized for the magnetizing surge if multiple contactors pull in simultaneously. ## What the AC-1 rating means for selection AC-1 is the resistive load category — heaters, incandescent lighting, resistive banks. If your load is motor (AC-3) or mixed, you need the motor-rated version (3RT2... with a different coil code) because the AC-3 breaking current is lower for the same frame. This part is for resistive switching, not motor starting.","metaTitle":"Siemens 3RT2346-1AK60 Contactor, AC-1 140 A, 4-Pole, 110 VAC","metaDescription":"Siemens 3RT2346-1AK60 contactor, AC-1 rated 140 A at 400 V / 40 °C, 4-pole, 110 V AC 50 Hz / 120 V 60 Hz coil.
