For motor loads, the AC-3 switching frequency is 750 operations per hour, which covers most conveyor, pump, and fan cycling without exceeding the contactor's thermal limit. Duty-class switching frequencies are specified: AC-1 (resistive) at 1,000 1/h, AC-2 and AC-3 (motor start/run) at 750 1/h, and AC-4 (plugging/inching) at 250 1/h. If your application involves frequent reversing or inching, the AC-4 ceiling of 250 cycles per hour is the governing limit — not the higher AC-3 figure. The coil draws 0.24 A at 50 Hz and 0.25 A at 60 Hz at its rated 24 V. That's a low control-power draw, so it won't stress a 24 VDC power supply shared with PLC outputs or sensors. ## Wiring and Terminal Details For doubled-up conductors, the range is 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². That covers standard control wiring up to 12 AWG and allows daisy-chaining through the same terminal without a separate junction point. ## Environmental and Lifecycle Considerations The mechanical life of the contactor is typically 30,000,000 operations — that's the expected service life before the mechanism wears out, not the electrical endurance under load. Electrical life depends on the switching duty and load current, but the mechanical figure gives you a ceiling for high-cycle applications like sorting lines or pick-and-place cells.","metaTitle":"Siemens 3RT2015-1AR61 SIRIUS Power Contactor, S00, 24 VDC Co","metaDescription":"Siemens SIRIUS 3RT2015-1AR61 power contactor, size S00, 24 VDC coil, screw terminals, 10 A rated current, current production.

The 3RT2015-1AR61 uses a 24 VDC coil, while the 3RT2015-1AK61 uses a different coil voltage. If your control voltage is fixed at 24 VDC, the 3RT2015-1AR61 is the direct fit; swapping to the 3RT2015-1AK61 would require a coil voltage change."},{"question":"What are the key dimensions of the 3RT2015-1AR61?","answer":"Width is 45 mm, height is 58 mm, and depth is 73 mm. These dimensions match the S00 frame size and fit standard 35 mm DIN rail."},{"question":"What wire sizes does the 3RT2015-1AR61 accept?","answer":"Solid or stranded wire from 0.5 to 4 mm². For two conductors per terminal, it accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm²."},{"question":"Will the 3RT2015-1AR61 drop into a panel designed for the 3RT2015-1AK61?","answer":"Yes, the physical footprint and mounting are identical — same S00 frame size, same 45 mm width, same DIN-rail clip. The only difference is the coil voltage, so as long as the control circuit supplies 24 VDC, it is a direct mechanical and electrical swap."},{"question":"What compliance documentation is available for the 3RT2015-1AR61?","answer":"As a Siemens SIRIUS product, it carries the usual CE marking for the European market and is designed to meet relevant IEC/EN standards for contactors (IEC 60947-4-1). RoHS and REACH declarations are available from Siemens documentation. Specific UL/CSA listings should be verified against the nameplate marking on the unit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT2015-1AR61","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/3RT2015-1AR61 when reusing this data.
