It provides three normally open instantaneous contacts (no delayed or lagging switching) and is designed for control-circuit switching, not main motor loads. ## Switching capacity — what the voltage-dependent ratings mean The 3RH1131-1AS00 carries a rated insulation voltage of 500 V AC (50/60 Hz) and a surge voltage resistance of 6 kV, which puts it in the standard control-circuit insulation class for 400 V line-fed panels. The switching current is voltage-dependent: at 24 V it handles 10 A, at 110 V it drops to 1 A, at 230 V it is rated 6 A, and at 400 V it switches 3 A. At 690 V the rating falls to 1 A. These are the thermal current ratings for the contacts — the actual make/break capacity for inductive loads like contactor coils or relay coils will be lower, so size the load against the AC-15 or DC-13 utilization category if the application involves solenoids or motor contactor coils. ## Mounting, wiring, and environment Shock resistance is 10g / 5 ms and 5g / 10 ms — adequate for standard industrial panel vibration but not for direct mounting on a high-impact machine frame. ## Contact reliability and endurance Mechanical endurance is 30 million switching operations typical. For a pulp and paper mill running consistency loops or dryer-section controls, that low-level reliability keeps the machine running without nuisance faults from contact oxidation.","metaTitle":"Siemens 3RH1131-1AS00 SIRIUS Auxiliary Contactor, S00, 3 NO","metaDescription":"Siemens 3RH1131-1AS00 SIRIUS auxiliary contactor, size S00, 3 NO contacts, 500 V rated insulation, IP20 front.
