The Siemens 3RH1131-1AP00 is a SIRIUS auxiliary contactor in size S00, carrying 3 normally open instantaneous contacts. Coil pulls in on 50 Hz (0.8...1.1) or 60 Hz (0.85...1.1) at 230 V.
Three NO contacts, no NC — that's the contact configuration on this block. If your BOM calls for a break contact, this isn't the variant; you'd need a 3RH1 with a different contact arrangement. The 10 A at 24 V is the thermal current for DC pilot duty; at 230 V AC it's 6 A, at 400 V it's 3 A. That's enough for a contactor coil or a small PLC output, not for power switching. Wire capacity runs 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or 2x 4 mm² solid — that's two conductors per terminal for daisy-chaining. The spring-cage variant (3RH6131-1AP00) uses the same footprint but changes the termination method; if your panel spec calls for spring terminals, the screw-clamp here won't match without rewiring.
The SIRIUS platform is Siemens' standard control gear line, so documentation (CE, UKCA, RoHS date 01.07.2006) is readily available.
Mounts on DIN rail via the screw-and-snap-on method — the screw provides vibration resistance, the snap-on gives quick placement. Shock rated at 10g / 5 ms and 5g / 10 ms, which covers most industrial panel vibration.
