Rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V, so it covers 24 VDC PLC outputs up to 690 VAC pilot circuits on the same block. ## Where it lands in a panel Size S00 footprint: 90 mm wide, 57.5 mm tall, 72 mm deep. That 72 mm depth is the key dimension for shallow enclosures or gland-plate clearance. Standing position on a horizontal mounting surface per the spec. Wire termination accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid — spring-cage or screw terminals, depending on the variant. The 24 V 10 A rating is the coil supply side — that's the contactor's own pick-up current, not the load it switches. The load-switching numbers are the ones that decide fit: 230 V at 6 A covers most pilot lights and solenoid valves; 400 V at 3 A handles medium-voltage control transformers; 690 V at 1 A is for high-voltage auxiliary circuits in MV switchgear. If your circuit draws more than those curves, you need a bigger frame or a contactor with a higher utilization category. Ambient range is -25 to +60 °C operating, -55 to +80 °C storage — fine for most indoor industrial panels but watch the derating above 40 °C if you're running near the current limits.","metaTitle":"Siemens 3RH1422-1AP00-1AA0 SIRIUS Auxiliary Contactor, Size","metaDescription":"Siemens 3RH1422-1AP00-1AA0 SIRIUS auxiliary contactor, size S00, 2 NO + 2 NC, screw/snap-on mount, IP20 front, 24V 10A rated.

The main difference is contact configuration — the 3RH2422-1AB00 carries 2 NO + 2 NC but with a different coil voltage rating. Check your control voltage before swapping; the footprint and mounting are identical, so it drops into the same DIN rail slot without rewiring the panel layout."},{"question":"What compliance documentation does Siemens provide for 3RH1422-1AP00-1AA0?","answer":"The part carries a substance prohibition date of 07/01/2006, which aligns with RoHS compliance.
