The 400 V rating matches the rated voltage of the coil (400 V AC at both 50 and 60 Hz). The unit accepts solid conductors: two wires of 0.5 to 1.5 mm², two of 0.75 to 2.5 mm², or a single 4 mm² per terminal. Shock resistance is 10g for 5 ms and 5g for 10 ms — fine for normal industrial vibration but not rated for heavy impact near presses or hammers.","metaTitle":"Siemens 3RH1122-1AV00 SIRIUS Auxiliary Contactor, Size S00,","metaDescription":"Siemens 3RH1122-1AV00 SIRIUS auxiliary contactor, size S00, 2 NO contacts, screw/snap-on mount, IP20 front.
