Rated operational current at AC-12 (resistive/control circuit duty) is 10 A, which covers most PLC input, relay coil, and signal lamp loads in a standard control panel. At 230 V the switching capacity drops to 6 A; at 400 V to 3 A — the AC-12 figure is the one that governs fit for a typical 24 VDC or 120 VAC control circuit. The S00 footprint — 45 mm wide, 57.5 mm tall, 72 mm deep — is the standard compact size that fits alongside S00 contactors and overload relays in a shared panel layout. Wire termination accepts solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. The spring-cage or screw terminals are sized for the auxiliary contact current range — no special lugging needed. ## Environmental and electrical ratings Rated surge voltage resistance is 6 kV, which aligns with IEC 60947-1 overvoltage category III for 400 V systems. Shock resistance is 10g / 5 ms and 5g / 10 ms — sufficient for most industrial machinery but not for high-impact applications like forging presses. The auxiliary contactor is designed to mount directly onto SIRIUS S00 contactors (3RT1 series) or be used as a standalone control relay. If you're replacing a 3RT1016-1AN22 or similar S00 power contactor and need the auxiliary block separately, this is the matching add-on. No rewiring of the control circuit is needed if the existing auxiliary contacts are in the same S00 footprint.","metaTitle":"Siemens 3RH1122-1AV60 SIRIUS Auxiliary Contactor, 10A AC-12,","metaDescription":"Siemens 3RH1122-1AV60 SIRIUS auxiliary contactor, S00 size, 10A AC-12, 2 NO + 2 NC, screw/snap-on mount, IP20 front, -25 to +60°C.

However, the 3RH1122-1AV60 is an auxiliary contactor (control circuit switching), while the 3RT1016-1AN22 is a main power contactor. They are not direct functional substitutes — the 3RH1122 is used for signal/control loads, not motor switching. For a direct auxiliary contactor replacement, stick with the 3RH1 series."},{"question":"What is the depth of the 3RH1122-1AV60?","answer":"The depth is 72 mm. The full dimensions are 45 mm width, 57.5 mm height, and 72 mm depth, which is the standard S00 frame size."},{"question":"What wire sizes does the 3RH1122-1AV60 accept?","answer":"Solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².

Both are S00 frame size with the same 45 mm width and DIN-rail mounting. However, the 3RH1122 is an auxiliary contactor (control circuit), not a power contactor — it cannot switch motor loads. If the panel originally used the 3RT1016 for motor starting, the 3RH1122 will fit the rail but won't perform the same function."},{"question":"What compliance documentation is available for the 3RH1122-1AV60?","answer":"The part carries a substance prohibitance date of 01.07.2006, indicating RoHS compliance. The reference code per IEC 81346-2 is K (contactors/relays). Standard Siemens SIRIUS documentation includes CE, UL, and CSA certifications, though specific cert marks are not listed in the basic spec set. The IP20 front rating and pollution degree 3 are per IEC 60947-1."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RH1122-1AV60","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/3RH1122-1AV60 when reusing this data.
