Mounts via screw or snap-on to a DIN rail, with the standard S00 footprint: 45 mm wide, 57.5 mm tall, 72 mm deep. Terminals accept solid conductors from 0.5 mm² up to 4 mm², with the clamping ranges split as 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), and 2x 4 mm². That covers the control wiring you'll typically run — 1.5 mm² for the coil circuit, 2.5 mm² for the contact loop back to the PLC input card. Front face is IP20 rated; the enclosure itself is designed for panel interior use where no washdown or dust ingress is expected. ## Contact ratings and switching For inductive DC switching, the numbers drop fast: 1 A at 110 V, 0.27 A at 220 V. At 230 V AC the contacts handle 6 A; at 400 V AC, 3 A; at 690 V AC, 1 A. If you're switching a DC brake coil or a contactor holding circuit, size the load against the DC voltage column — the AC-12 number won't apply. Mechanical endurance is listed at 30 million operating cycles typical for the contactor. No electrical endurance figure is given under load, so that mechanical number is the benchmark for replacement intervals in dry-circuit or lightly loaded signal switching. Shock resistance is tested at 10g / 5 ms and 5g / 10 ms — enough for most industrial machinery but not for direct mounting on a high-impact press. Altitude limit is 2 000 m above sea level.","metaTitle":"Siemens 3RH1131-1AH00 SIRIUS Auxiliary Contactor, 10A AC-12,","metaDescription":"Siemens 3RH1131-1AH00 SIRIUS auxiliary contactor, 10A AC-12 rated, size S00, 3 NO + 1 NC contacts.
