The 10 A at 24 V rating defines the switching capacity for DC control circuits — enough for a bank of PLC outputs or relay coils in a typical 24 VDC panel. At 230 V AC the same contact handles 10 A, so it doubles for mixed-voltage auxiliary circuits without derating the contact block. The 2 NO instantaneous contacts switch in 4–15 ms arcing time, fast enough for interlocking sequences on conveyor or pump controls. ## Deployment context The S00 size is the smallest SIRIUS frame, so it fits in tight panel layouts alongside contactors and overload relays of the same family. Substance prohibitance date of 10/01/2009 aligns with RoHS compliance; the part meets EU restriction deadlines for lead and other substances.","metaTitle":"Siemens 3RH2122-4AN60 SIRIUS Auxiliary Contactor, 45 mm, 10","metaDescription":"Siemens 3RH2122-4AN60 SIRIUS auxiliary contactor, 2 NO contacts, 10 A at 24 V, 45 mm width, 73 mm depth.
