The Size S00 frame keeps the footprint tight at 45 mm wide by 57.5 mm tall by 72 mm deep, so it slots into a crowded DIN-rail enclosure without eating up rows. ## Mounting and wiring — panel fit Wire terminals accept solid conductors from 0.5 mm² up to 4 mm² (two per clamp), or AWG 20–12 for the stranded equivalent. The headline 10 A AC-12 rating governs resistive control loads. For inductive loads the current drops: 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. At 24 V DC the contact carries 10 A, but at 110 V DC it falls to 1 A and at 220 V DC to 0.27 A — so if you're switching a DC solenoid bank at higher voltage, watch the derating curve. The contact reliability spec (one incorrect operation per 100 million at 17 V, 1 mA) means it handles dry logic-level signals without needing a separate interface relay, which is useful when a PLC output drives a long cable run to the contactor.","metaTitle":"Siemens SIRIUS 3RH1122-1AT60 Auxiliary Contactor, Size S00","metaDescription":"Siemens SIRIUS 3RH1122-1AT60 auxiliary contactor, Size S00, 45 mm wide.
