It carries two instantaneous normally-open contacts rated at 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — these are the switching capacities for the auxiliary circuit, not a main power path. Snap-on mounting to DIN rail or direct screw fixing — the same 45 mm wide footprint as the S00 contactor range. Terminals accept 2x (0.25 to 2.5 mm²) solid or 2x (24 to 14 AWG) stranded. ## Contact ratings and switching reliability The two NO contacts are instantaneous (no delayed or lagging switching). Storage and transport range extends to -55 to +80 °C.","metaTitle":"Siemens 3RH1122-2BB40-ZW96 SIRIUS Auxiliary Contactor, 24 V","metaDescription":"Siemens 3RH1122-2BB40-ZW96 SIRIUS auxiliary contactor, 24 V DC coil, size S00, 45 mm wide, 2 NO contacts, IP20 front.
