It carries 2 normally-open and 2 normally-closed instantaneous contacts, rated 10 A at 24 V for AC-12 duty (resistive loads at unity power factor). The AC-12 rating is what governs its use in control transformers and pilot-duty circuits — the 10 A figure is the full-load resistive current it can make and break, not a motor-switching number. Shock-rated at 10g / 5 ms and 5g / 10 ms — solid for machine-mounted panels near presses or conveyors. ## Ratings and Application Context Surge voltage resistance is 6 kV, matching the impulse withstand for 400 V line-to-ground circuits. IP20 on the front keeps fingers out but expects enclosure protection against liquids. Contact reliability is specified as one incorrect switching operation per 100 million cycles at 17 V, 1 mA — relevant for low-energy PLC input signals where oxide films on dry contacts can cause intermittents.","metaTitle":"Siemens 3RH1122-2AT60 SIRIUS Auxiliary Contactor, Size S00,","metaDescription":"Siemens 3RH1122-2AT60 SIRIUS auxiliary contactor, Size S00, 2 NO + 2 NC, 10 A AC-12 at 24 V.
