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.","metaTitle":"Siemens 3RH1131-1AP00 SIRIUS Auxiliary Contactor, 3 NO, S00,","metaDescription":"Siemens 3RH1131-1AP00 SIRIUS auxiliary contactor, size S00, 3 NO contacts, 10 A at 24 V, screw/snap-on mount, IP20 front.

The difference is termination: screw clamp on the 3RH1131, spring cage on the 3RH6131. They share the same footprint, so a panel designed for one can accept the other without rewiring the DIN rail or changing the enclosure layout, but the wire termination method differs."},{"question":"What is the depth of 3RH1131-1AP00?","answer":"72 mm depth, 45 mm width, 57.5 mm height — size S00 footprint.
