The coil is rated for 24 V at both 50 Hz and 60 Hz, with a tolerance band of 0.8–1.1 at 50 Hz and 0.85–1.1 at 60 Hz, so it holds in across a saggy line but drops out cleanly below the undervoltage threshold. The 3RH1131-1AB00-1AA0's contact ratings are given per voltage, not as a single thermal current. At 24 V it switches 10 A; at 230 V it switches 6 A; at 400 V it drops to 3 A; at 690 V it handles 1 A. That derating curve is typical for an auxiliary contactor — the arc-extinction gap is fixed, so higher voltage reduces the current the contacts can break. For a 24 VDC pilot circuit the 10 A rating is generous; for a 230 VAC signal lamp string the 6 A limit governs. The 1 A at 690 V tells you this part can switch a 690 V control transformer primary, but only at low current. If you are switching PLC digital inputs or relay coils in the milliampere range, this contactor will not give you intermittent opens. ## Mechanical endurance and environmental limits Shock resistance is 10g for 5 ms and 5g for 10 ms, which covers most industrial vibration environments short of a stamping press or crusher. ## Wiring and compliance The screw terminals accept solid conductors: two per clamp for 0.5–1.5 mm², two for 0.75–2.5 mm², and a single 4 mm². RoHS compliance date is July 1, 2006 — the part was designed to meet the original EU RoHS directive. No UL or CSA listing appears in the evidence, so verify with your local Siemens office if a UL 508 listing is required for your panel.","metaTitle":"Siemens 3RH1131-1AB00-1AA0 SIRIUS Auxiliary Contactor, S00,","metaDescription":"Siemens SIRIUS 3RH1131-1AB00-1AA0 auxiliary contactor, size S00, 3 NO contacts, 24 V 50/60 Hz coil, screw/snap-on mount.
