The 10 A rating at 24 V (AC-12) covers most control transformer and signal loads inside a cabinet. At 110 V the contact rating drops to 1 A, and at 220 V to 0.27 A — so for higher-voltage control circuits you need to check the load current against the curve. The 500 V rated insulation voltage means the contacts can switch circuits up to that level, typical for motor control centers. The 6 kV surge voltage resistance (rated impulse withstand) ensures the contactor holds up against switching transients on the line. ## Mounting and environment The 45 mm width, 57.5 mm height, and 72 mm depth fit the standard S00 footprint — it shares the same panel cutout and DIN-rail space as other S00 contactors and relays.","metaTitle":"Siemens SIRIUS 3RH1122-1AS00 Auxiliary Contactor, 2 NO + 2 N","metaDescription":"Siemens SIRIUS 3RH1122-1AS00 auxiliary contactor, 2 NO + 2 NC, rated 10 A at 24 V, 500 V AC, S00 frame.
