The contact arrangement provides 2 normally-open and 2 normally-closed instantaneous contacts — no delayed or make-before-break switching — so it's a straight signal repeater for PLC outputs or pushbutton circuits. The IP20 front protection means it's suitable for enclosed panels where no washdown or dust ingress is expected. ## Current ratings across the voltage range The 3RH1122-1AU00's switching capacity varies with voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. At 110 V it's rated 1 A, at 220 V it drops to 0.27 A — these lower figures reflect the contact gap's ability to extinguish the arc at higher voltages. For a tire-curing press environment where control circuits run at 24 VDC or 230 VAC, the 10 A or 6 A rating respectively gives enough headroom for multiple solenoid valves or indicator lamps without paralleling contacts. ## Mechanical endurance and environmental limits Shock resistance is specified at 10g / 5 ms and 5g / 10 ms, which handles vibration from nearby motor starters or conveyor drives.","metaTitle":"Siemens 3RH1122-1AU00 SIRIUS Auxiliary Contactor, 10 A AC-12","metaDescription":"Siemens 3RH1122-1AU00 SIRIUS auxiliary contactor, S00 frame, 10 A AC-12 at 24 V, screw/snap-on mount, IP20 front, -25 to +60 °C.
