That wide-range coil simplifies stocking — one part covers a spread of control voltages common in European and North American panels. Envelope is 140 mm high by 96 mm wide by 152 mm deep. The depth matters when you're routing wires past a gland plate or trying to squeeze a row of contactors into a shallow enclosure — 152 mm is not a shallow-mount part. Main contacts accept stranded wire from 6 to 70 mm² — that's a heavy lug range, sized for the S3 frame's current handling. The auxiliary switch is built in, with contacts rated at 10 A at 24 V, 6 A at 60 V, 6 A at 230 V, and 3 A at 400 V. Mechanical life is listed at 10 million operations typical. That's a high-cycle figure — suitable for frequent start/stop applications like conveyor indexing or pump cycling, not just infrequent isolation. The storage range is wider — that's the handling and shipping limit, not the running limit. Skimp on those and you lose airflow and arc clearance. Solid wire termination on the aux/coil terminals accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). The coil terminals are screw-type — no spring cages here, so torque them to spec and avoid stranded whiskers shorting to the frame.","metaTitle":"Siemens 3RT2348-1NF30 SIRIUS Contactor, Size S3, 83-155V AC/","metaDescription":"Siemens SIRIUS 3RT2348-1NF30 contactor, size S3. 83-155 V AC/DC coil, screw-type terminals.
