The contacts are rated for 10 A at 24 V, 1 A at 110 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V — so the 110 V DC coil is the one to match, but the contacts can handle a wide range of AC and DC loads up to 690 V. This auxiliary contactor is Size S00, meaning it occupies a 45 mm wide DIN-rail footprint — typical for control cabinets where space is tight. That flexibility matters when you're squeezing it into a crowded panel next to a main contactor or a terminal block. Terminals accept solid conductors: 2x 0.5…1.5 mm², 2x 0.75…2.5 mm², or 2x 4 mm², plus the AWG equivalents (2x 20…16, 2x 18…14, 1x 12). Shock resistance is 10g for 5 ms and 5g for 10 ms — enough for most machine-mounted applications but not for high-impact presses without additional isolation.","metaTitle":"Siemens SIRIUS 3RH1122-1BF40-0AA6 Auxiliary Contactor, 110 V","metaDescription":"Siemens SIRIUS 3RH1122-1BF40-0AA6 auxiliary contactor, 110 V DC coil, 4 NO + 2 NC contacts, Size S00, IP20 front, screw and snap-on mounting, current production.
