It's the signal-switching arm of a motor starter or control circuit, not the main power path. Screw and snap-on mounting means you can clip it to the rail or bolt it to a backplate — whichever the panel-builder prefers. The contact reliability spec — one incorrect switching operation per 100 million at 17 V, 1 mA — tells you it's built for dry-circuit PLC-level signals, not just power contacts. That's the difference between a relay that chatters on a 24 VDC input card and one that clicks clean for years. Rated at 10 A at 24 V (both 50 and 60 Hz), 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. These are the thermal continuous currents; they define the contactor's capacity to pass current through the closed contacts, not the making/breaking capability on motor inrush. For motor switching, you'd size a main contactor upstream. Surge voltage resistance rated at 6 kV, pollution degree 3 — it's designed for industrial environments where transients and conductive dust are normal. ## Mounting and wiring reality That helps when you're wedging it into a crowded panel and the rail isn't perfectly level. Wire sizes accepted: 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², and 2x 4 mm² solid. That covers most control wiring from signal loops to short motor leads. No ferrule size restrictions stated, so standard ferruled ends should work. Shock-rated at 10g / 5 ms and 5g / 10 ms — it'll survive a forklift bump to the panel or a door slam during commissioning. The product extension auxiliary switch is supported, meaning if you need more contacts later, you can add a side-mount block without swapping the base unit.","metaTitle":"Siemens SIRIUS 3RH1131-1AB00-0TK0-ZX95 Auxiliary Contactor,","metaDescription":"Siemens SIRIUS auxiliary contactor 3RH1131-1AB00-0TK0-ZX95, Size S00, 3 instantaneous NO contacts, IP20 front, screw/snap-on mount.
