Rated operational current varies with voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — matching the derating curve for AC loads across typical control voltages. Substance prohibition compliance is documented with a reference date of 07/01/2006, aligning with RoHS requirements. Dimensions are 73 mm deep, 45 mm wide, and 60 mm high — the S00 footprint fits standard control panel layouts and matches other SIRIUS S00 components for uniform rail spacing. Shock resistance is specified at 10g / 5 ms and 5g / 10 ms, suitable for applications on machinery with moderate vibration profiles. Solid conductor capacity is 2x (0.25... 2.5 mm²), accepting standard control wiring with or without ferrules. ## Contact reliability and endurance Mechanical endurance of the contactor is rated at 30 million typical operating cycles, reflecting the S00 family's design for high-duty applications.","metaTitle":"Siemens 3RH1140-2AC00-0TK1 SIRIUS Auxiliary Contactor, 4 NO,","metaDescription":"Siemens SIRIUS 3RH1140-2AC00-0TK1 auxiliary contactor, 4 NO contacts, size S00, 73 mm depth, IP20 front, screw and snap-on mounting.
