The size S00 footprint (45 mm wide, 57.5 mm tall, 72 mm deep) is the standard compact frame for this class in the SIRIUS family, and the screw and snap-on mounting lets it clip directly onto a DIN rail or fasten with screws into a backplate. The 10 A AC-12 rating is the headline — it governs resistive switching at line voltage. For inductive DC loads the derating is steep: 10 A at 24 V drops to 1 A at 110 V, 0.27 A at 220 V, and 0.1 A at 690 V. That means this contactor is sized for control transformers, pilot lights, and PLC output isolation, not for motor starting. The front carries IP20 protection.","metaTitle":"Siemens 3RH1122-1AU60-1AA0 SIRIUS Auxiliary Contactor, 10 A","metaDescription":"Siemens SIRIUS 3RH1122-1AU60-1AA0 auxiliary contactor, 10 A AC-12 max, 2 NO + 2 NC contacts, size S00, 45 mm wide, IP20 front.
