It's designed for control-circuit switching — feeding signal voltage to contactor coils, relays, or PLC inputs — not for main motor power. The 45 mm width and snap-on mounting let it land directly on a DIN rail alongside the main contactor it follows. The 10 A AC-12 rating is the resistive-load switching capacity at the control voltage — this is the contactor's real-world ceiling for pilot-duty circuits like contactor coils or indicator lamps. Those numbers drop further for DC switching: 10 A at 24 V, 1 A at 110 V, and only 0.27 A at 220 V. If your panel uses 24 VDC control and each coil draws 0.5 A, one set of contacts can handle up to 20 coils in parallel — well within the margin. The 2 NO configuration means zero NC break contacts on this variant; if your safety circuit needs a feedback loop, you'll need the 3RH1122-1AR60 with a different block or an add-on auxiliary switch. The S00 footprint — 72 mm deep, 45 mm wide, 57.5 mm high — matches the standard Siemens S00 contactor base, so it clips directly beside a 3RT1 contactor without extra bridging hardware. Shock resistance is 10g / 5 ms and 5g / 10 ms — fine for standard industrial panels but not for high-vibration mobile equipment. The screw terminals accept solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². That covers standard control wiring from 20 AWG to roughly 12 AWG. No spring-cage option on this variant — if your shop standardizes on push-in terminals, look at the 3RH2 series. The IP20 front protection means the terminals are finger-safe once the panel door is closed, but the contactor itself isn't sealed against dust ingress.","metaTitle":"Siemens 3RH1122-1AR60 SIRIUS Auxiliary Contactor, 2 NO, 10 A","metaDescription":"Siemens SIRIUS 3RH1122-1AR60 auxiliary contactor, size S00, 2 NO contacts, 10 A AC-12 rated current.
