The contactor mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, and its mounting position allows +/-180° rotation on a vertical surface plus +/-22.5° tilt forward and backward — useful when panel layout forces an unconventional orientation. The 3RT2047-1SP30 is rated for AC-1 maximum 900 operating cycles per hour, AC-3 maximum 850 cycles per hour, and AC-4 maximum 200 cycles per hour. The AC-3 figure governs motor switching duty — 850 ops/h means it handles frequent starts of a squirrel-cage motor without exceeding thermal limits, typical for conveyor or pump cycling. Mechanical life is typically 5,000,000 operations, and MTBF is listed at 52 a — a reliability figure that supports long service intervals in continuous-process lines. The main contact configuration is 10... 2 (normally open / normally closed), and an auxiliary switch is included. For control-circuit switching at 24 V the rated value is 10 A; at 48 V and 60 V it drops to 2 A — important when selecting the contactor for DC control loads where the lower voltage reduces arc-quenching capability. The inrush current peak is 43 A, which the coil driver must supply momentarily during pickup. Operating temperature range is -25... +60 °C, storage -55... +80 °C. These spacings prevent arc flashover and ensure adequate cooling; panel builders should respect them, especially when grouping multiple contactors in a row. Main circuit terminals accept solid conductors 2.5... 16 mm² and stranded conductors 6... 70 mm². The coil terminals are screw-type, accepting 2x (0.5... 1.5 mm²) solid or stranded, or 2x (0.75... 2.5 mm²). The wide stranded range (up to 70 mm²) covers heavy power feeds for the S3 frame size — typical for motor circuits up to roughly 30-40 kW depending on duty. Arcing time is 10... 20 ms, and operate time (both AC and DC) is 38... 57 ms, consistent across coil supply type.","metaTitle":"Siemens 3RT2047-1SP30 SIRIUS Power Contactor, Size S3, 175-2","metaDescription":"Siemens 3RT2047-1SP30 SIRIUS power contactor, size S3, 175-280 VAC coil, 152 mm depth, MTBF 52 a.
