Rated breaking capacity at 24 V is 10 A, which covers small motors, solenoid valves, and lighting contactor duty. At 400 V the rating drops to 3 A, so keep that in mind if you're switching a 400 V motor — the AC-3 motor rating governs the real-world load, not the 24 V number. Switching frequency varies by duty class: 1 000 cycles/hour for AC-1 resistive loads, 750 for AC-2 and AC-3 motor duty, and 250 for AC-4 plugging/reversing. That 250 limit on AC-4 is the one that catches people out on reversing starter applications. That side clearance is the one to watch when packing multiple contactors side-by-side. Wire range accepts 0.5 to 4 mm² solid or stranded, and 2x (0.5 to 4 mm²) for looping through. Spring terminals mean no re-torquing after thermal cycling — a reliability win for high-vibration environments like conveyor lines. That covers most indoor panel environments; if your enclosure sees sustained +60 °C ambient, verify the coil hold-in voltage doesn't sag near the dropout threshold. The 10 A rating at 24 V is the maximum breaking capacity at that voltage — it's not a continuous current rating. For continuous motor current, use the AC-3 rating (not explicitly listed here, but the S00 frame typically handles up to 7 A AC-3). The 3 A at 400 V confirms it's a small-frame contactor, not for main motor switching above about 2.2 kW. Auxiliary switch is included (yes), which saves ordering a separate side-mount block for basic status feedback. The main contact life is rated at 20 to 12 million operations typical — that's the mechanical endurance, not electrical. Electrical life depends on the switching load and frequency; at AC-3 750 cycles/hour, expect significantly fewer.","metaTitle":"Siemens 3RT2016-2AD01 SIRIUS Power Contactor, S00, 24 VDC","metaDescription":"Siemens SIRIUS 3RT2016-2AD01 power contactor, size S00, 24 VDC coil, spring terminals, 10 A rated breaking capacity at 24 V.

The 3RT2016-2AD01 uses spring terminals on the coil, which eliminates screw-torque verification during installation. Panel wiring is otherwise identical; it drops into the same DIN-rail footprint without rewiring the main contacts."},{"question":"What is the depth of the 3RT2016-2AD01?","answer":"The depth is 73 mm. Combined with the 45 mm width and 70 mm height, the S00 frame fits standard 35 mm DIN-rail enclosures with the specified clearance gaps (10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side)."},{"question":"What wire sizes does the 3RT2016-2AD01 accept?","answer":"Solid or stranded wire from 0.5 to 4 mm², and 2x (0.5 to 4 mm²) for looping through. The spring-type terminals accept ferruled stranded conductors — strip to the correct length and push in until the cage clicks."},{"question":"Will the 3RT2016-2AD01 drop into a panel wired for the 3RT2016-1AH01?","answer":"Yes, the mounting footprint and main contact terminal positions are identical — both are S00 frame on 35 mm DIN rail. The only difference is the coil connection: the 2AD01 uses spring terminals, the 1AH01 uses screw terminals. If the panel was wired with ring terminals for the coil, you'll need to swap to ferruled stranded or bare solid wire for the spring cage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT2016-2AD01","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/3RT2016-2AD01 when reusing this data.
