AC-4 at 400 V is 8.5 A, covering reversing or inching duty where the contacts make and break under full load. The 24 VDC coil holds reliably at nominal voltage; dropout below 18 V is typical for this class, so verify your control supply stays above that threshold. The contactor measures 45 mm wide, 57.5 mm tall, and 72 mm deep, fitting the S00 footprint. The IP20 finger-safe enclosure on the front and terminals means the panel builder can work near live busbars without additional shrouding — standard for control cabinets. ## Terminal and wiring The screw terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, with a maximum of 2x (0.75 to 4 mm²) per clamp. AWG equivalents are 2x (20 to 16) solid and 2x (18 to 14) stranded, plus a single 12 AWG. Strip length is not stated in this record, but the S00 family standard is 8 mm — verify against the terminal marking before wiring.","metaTitle":"Siemens 3RT1016-1AU61 SIRIUS Power Contactor, S00, 3-Pole, 2","metaDescription":"Siemens SIRIUS 3RT1016-1AU61 power contactor, size S00, 3 NO main contacts, 24 VDC coil, screw terminals, IP20.

If your panel wiring is already set for screw clamps, the 2AP02 would require re-termination. Both share the same mounting footprint and AC-2/AC-4 ratings."},{"question":"What compliance documentation is available for the 3RT1016-1AU61?","answer":"The part carries a reference code per DIN EN 81346-2 (letter Q for switching devices). Standard Siemens SIRIUS documentation includes a CE declaration of conformity, RoHS and REACH compliance statements, and UL/CSA certification files. Specific cert numbers are not listed in this record; they are available through the Siemens Industry Online Support portal."},{"question":"Will the 3RT1016-1AU61 drop into a panel designed for the 3RT1016-2AP02?","answer":"Yes, the mechanical footprint is identical — both are S00 size, snap onto 35 mm DIN rail, and share the same 45 mm width, 57.5 mm height, and 72 mm depth. The difference is terminal type: the 1AU61 uses screw terminals, while the 2AP02 uses spring-cage terminals. If the panel wiring is already terminated with ferrules for spring-cage, you would need to swap to ring or fork terminals for the screw clamps."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1016-1AU61","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1016-1AU61 when reusing this data.
