At 110 V the rated current is 1 A, and at 220 V it is 0.27 A. These values define the contact's thermal and breaking capability at each voltage level — select the row matching your control voltage. Its 45 mm width and 57.5 mm height fit the standard S00 footprint, with a depth of 72 mm. ## Wire Termination and Environmental Limits Terminals accept solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm². AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. This covers common control wiring sizes for auxiliary circuits. Front-side protection class is IP20, suitable for enclosed panel installation. Shock resistance: 10g for 5 ms and 5g for 10 ms. Mechanical endurance: 30,000,000 operating cycles typical. ## Coil Power and Auxiliary Extension DC magnet coil draws 3.2 W for closing and holding. The product extension auxiliary switch is supported (yes), meaning additional contact blocks can be added to the side of this base unit. Substance prohibitance date of 01 July 2006 confirms RoHS compliance for the part as manufactured after that date. No further compliance documentation (UL, CSA, CE) is explicitly listed in the evidence, but the SIRIUS series typically carries these approvals — verify the specific nameplate marking on the unit received.","metaTitle":"Siemens 3RH1122-1BG40-0AA6 SIRIUS Auxiliary Contactor, Size","metaDescription":"Siemens SIRIUS 3RH1122-1BG40-0AA6 auxiliary contactor, size S00, 45mm width, 2 NO + 2 NC contacts.
