The 65 A inrush peak tells you the coil pull-in is hefty, so make sure your control transformer can deliver that surge without dropping the rest of the 24 VDC bus. Rated operating range covered in the spec table; off-state leakage stays under the listed maximum at 25 °C, derate per the thermal curve above 40 °C. Storage temperature exceeds operating range — handling, not running, is what that limit governs. Width 70 mm, height 140 mm, depth 152 mm — the depth is the dimension to watch when the panel door clearance is tight; 152 mm means a standard 200 mm deep enclosure leaves about 48 mm for wiring and arc chutes. Solid conductor range 2.5... 16 mm² for the main circuit; stranded 6... 70 mm² also accepted. The spring-type coil terminals accept 2x (0.5... 2.5 mm²) solid or stranded. ## Ratings that matter for the buyer The 24 V rated value on the auxiliary switch is 10 A — that is the contact rating for the aux block, not the main poles. At 48 V and 60 V the aux drops to 2 A; at 110 V it is 1 A. So if you are switching a 24 VDC pilot light or PLC input, 10 A is plenty, but if you try to run a 110 VAC solenoid off the aux, you are limited to 1 A. Switching frequency at AC-3 maximum is 850 1/h — that is 850 operations per hour under motor load, which is typical for a conveyor or pump start-stop cycle. Arcing time is 10... 20 ms; the AC and DC operate times are both 38... 57 ms. Coil holding power at 50/60 Hz is 3.5 VA — a light load on the control transformer once the contactor is pulled in.","metaTitle":"Siemens 3RT2047-3NP30 SIRIUS Power Contactor, S3, 175-280 VA","metaDescription":"Siemens 3RT2047-3NP30 SIRIUS S3 power contactor. 175-280 VAC coil, spring-type terminals, 65 A inrush peak.
