The 2 NO contacts give you two independent signal paths — enough for a run-permissive and a fault-feedback on a single contactor. That helps when the panel layout is tight and the contactor has to sit at an angle to clear busbars or cable ducts. The IP20 front protection keeps fingers and tools out but expects enclosure-level sealing. Shock resistance rated at 10g / 5 ms and 5g / 10 ms — relevant for crane or shuttle applications where vibration and jolts are routine.","metaTitle":"Siemens SIRIUS 3RH1122-2AK20 Auxiliary Contactor, 10 A AC-12","metaDescription":"Siemens SIRIUS 3RH1122-2AK20 auxiliary contactor, 10 A AC-12 rated, 2 NO contacts, S00 frame, screw/snap-on mount.
