Auxiliary contacts are rated for PLC-level signals — the contact reliability spec calls out acceptability for 17 V, 5 mA, meaning the contacts wet low-energy logic inputs without needing a separate interface relay. ## DIN-rail fit and terminal wiring The IP20 finger protection on the front and terminals means the contactor is touch-safe in a closed panel — no additional shrouding needed for routine access. This helps when the contactor sits on a swing frame or in a tight enclosure corner. ## Coil power and environmental limits The magnet coil draws 0.82 W during closing and only 0.24 W holding — the low holding power reduces heat buildup inside a densely packed panel. Pollution degree 3 means the contactor is rated for conductive pollution environments typical of industrial control panels without conformal coating. Surge voltage resistance is 6 kV, and shock resistance is 12.5g for 5 ms or 7.8g for 10 ms sine pulse — adequate for most machine-mounted panels but check if the application has repetitive high-g impacts. ## Fuse coordination for short-circuit protection For type 2 coordination (contactor remains operational after clearing), the fuse drops to 25 A. The 25 A limit is the one to design to if the contactor must survive a fault without replacement. The S0 frame size and 3-pole NO configuration are standard across the SIRIUS family, so a parametric match is straightforward if a variant is needed.","metaTitle":"Siemens 3RT7025-1AF00 SIRIUS Contactor, 3-Pole, 690 V AC-3","metaDescription":"Siemens 3RT7025-1AF00 SIRIUS contactor, 3-pole NO, 690 V AC-3 max, S0 frame, screw terminals, IP20.
