Mounting is via screw or snap-on onto 35 mm DIN rail; the mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, giving flexibility in crowded enclosures. Clearance distances are specified: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side — these are the minimum air gaps to maintain for arc flash and heat dissipation per the datasheet. ## Contact ratings and switching capability Three instantaneous NO contacts are rated for AC and DC switching: at 24 V rated value the contact carries 10 A, at 230 V rated value also 10 A, and at 400 V rated value 3 A — these are the thermal current limits for the contact set under the stated voltage conditions. DC switching ratings are given per voltage step: 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 0.5 A at 440 V, 0.26 A at 600 V — the current drops as voltage rises due to arc extinction limits in DC circuits. Mechanical endurance is 5,000,000 operating cycles typical; the maximum switching frequency at AC is 10,000 operations per hour, which sets the duty cycle for high-speed applications like conveyor or packaging lines. ## Lifecycle and sourcing posture No official successor or cross-reference is listed — this is the direct active order code.","metaTitle":"Siemens 3RH2431-1UW80 SIRIUS Auxiliary Contactor, 3 NO","metaDescription":"Siemens 3RH2431-1UW80 SIRIUS auxiliary contactor, size S00, 3 NO contacts, 90 mm width, 117 mm depth.
