The 10 A rating at 24 V (AC-12) covers resistive and transformer loads at that voltage. The AC-2 rating of 4 kW at 400 V applies to slip-ring motor starting. The mechanical life of 30,000,000 cycles tells you the contactor is built for high-cycle applications like conveyor or packaging lines. The IP20 protection on the front and terminals means it's finger-safe inside an enclosure but not washdown-rated. Screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded conductors. These are the values to specify when designing the branch circuit protection.","metaTitle":"Siemens 3RT1016-1AQ05 SIRIUS Power Contactor, S00, 24 VDC 10","metaDescription":"Siemens 3RT1016-1AQ05 SIRIUS power contactor, size S00, 3-pole, 24 VDC coil, 10 A rated operational current at 24 V.

If your panel is wired for screw terminals, the 3RT1016-1AQ05 is the direct fit; swapping to the -2AP02 would require re-terminating the control wiring."},{"question":"What are the key ratings for this contactor?","answer":"Rated operational current 10 A at 24 V (AC-12), AC-4 rating 8.5 A at 400 V, AC-2 rating 4 kW at 400 V.

RoHS and REACH declarations are standard for Siemens SIRIUS products. UL/CSA listings are typical for the series but should be confirmed per the specific catalog number."},{"question":"Will 3RT1016-1AQ05 drop into a panel specified for 3RT1016-2AP02?","answer":"The mounting footprint (45 mm width, DIN rail) and main circuit ratings are identical. The difference is the terminal type: screw-type on the -1AQ05 versus spring-cage on the -2AP02. If the panel wiring uses ferrules or bare wire, the screw terminals are compatible; if the existing wiring is terminated with spring-cage-specific ferrules, no change is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1016-1AQ05","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/3RT1016-1AQ05 when reusing this data.
