Dimensions are 70 mm wide, 140 mm high, and 152 mm deep — the depth is the critical dimension for enclosure depth selection, particularly when panel depth is constrained by back-panel wiring or gland plates. ## Mounting position flexibility and clearance requirements The storage ceiling matters for spares held in unconditioned warehouses or on-site cabinets near process heat. ## Coil and switching performance data for control system integration Inrush current peak is 1.5 A, which the control supply must support during pickup without voltage sag. Operate time is 38–57 ms for both AC and DC coil types, and arcing time is 10–20 ms. These timing windows are consistent enough for sequence interlocking in motor starter circuits without adding external delay timers. ## Power and auxiliary circuit wiring capacity Main power terminals accept stranded wire from 6 to 70 mm², covering motor feeder sizes up to roughly 50–70 mm² for high-current loads. These ratings cover both AC signal loads and DC pilot circuits for PLC inputs. ## Lifecycle status and sourcing posture Mechanical endurance is 10 million cycles typical, which sets the maintenance interval for high-duty-cycle applications like conveyor or pump motor switching.","metaTitle":"Siemens 3RT2448-1NF30 SIRIUS Contactor, Size S3","metaDescription":"Siemens 3RT2448-1NF30 SIRIUS contactor, Size S3 frame, 83-155 V AC/DC coil, screw and snap-on 35 mm DIN rail mount.
