The AC-12 rating is the key figure for control-circuit switching — it defines the make-and-break capability for resistive loads, not motor inrush. Mounting is via screw or snap-on onto a DIN rail, with the size S00 footprint (57.5 mm high, 90 mm wide, 72 mm deep) fitting standard panel layouts. Wire capacity covers solid and stranded conductors: 2x 0.5…1.5 mm², 2x 0.75…2.5 mm², or 2x 4 mm² per terminal. That range handles most control-circuit wiring from signal-level through power-limited circuits. ## Switching capacity across control voltages The contact ratings drop with voltage as expected for a DC-13 / AC-15 auxiliary contact block. At 24 V it switches 10 A (AC-12); at 110 V the rated current is 1 A; at 230 V it's 6 A; at 400 V it's 3 A; and at 690 V it's 1 A. These are the maximum break currents at each voltage level — for a given application, match the load's inrush and steady-state current to the appropriate voltage row. ## Panel integration and environmental limits Clearance: zero mm required at the side for air circulation. Shock resistance is 10g for 5 ms and 5g for 10 ms, adequate for most industrial machinery but not for extreme shock applications like forging presses without additional isolation.","metaTitle":"Siemens 3RH1422-1AB00 SIRIUS Auxiliary Contactor, 2 NO, Size","metaDescription":"Siemens SIRIUS auxiliary contactor 3RH1422-1AB00, 2 NO contacts, size S00, screw/snap-on mount, 10 A AC-12, IP20 front.

The primary difference is the coil voltage; the 3RH1422-1AB00 uses a 24 V AC/DC coil, while the 3RH2422-1AB00 uses a different coil voltage. Panel cutout and wiring footprint are identical, so a swap requires only verifying the coil supply."},{"question":"What are the key switching ratings for 3RH1422-1AB00?","answer":"AC-12 rated operational current is 10 A at 24 V. At 230 V it switches 6 A; at 400 V, 3 A; at 690 V, 1 A. For DC control circuits at 24 V, the rated current is 10 A. These are the maximum break currents at each voltage level."},{"question":"Will 3RH1422-1AB00 drop into a panel specified for 3RH2422-1AB00 without rewiring?","answer":"Yes, the mechanical dimensions and mounting are identical — both are size S00 with the same 57.5 x 90 x 72 mm footprint and screw/snap-on DIN rail mounting. The wiring terminals accept the same conductor sizes. The only difference is the coil voltage rating, so verify the control supply matches the coil before installing."},{"question":"How do I get current pricing and availability for 3RH1422-1AB00?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution channels.
