At 45 mm wide and 72 mm deep, it occupies a single DIN-rail slot alongside its parent contactor. The screw and snap-on mounting lets you clip it onto the rail or onto the contactor's side without tools — common for panel builders wiring control circuits. Pollution degree 3 means this contactor is rated for environments where conductive dust settles on the terminals — exactly what a cement plant control room sees. The IP20 front keeps fingers and tools out but does not seal against airborne grit; the enclosure around the panel provides that seal. Storage and transport range -55 to +80 °C means it survives a hot truck or warehouse without degrading. Shock resistance 10g / 5 ms and 5g / 10 ms is enough for normal machine vibration and handling drops. Contact reliability is rated at one incorrect switching operation per 100 million cycles at 17 V and 1 mA — that is the dry-circuit limit. For PLC-level signals (24 VDC, 10 A rated at 24 V), this contactor switches reliably without gold-plating. ## Wiring and mounting notes Terminals accept solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². No leading or delayed switching action — all three contacts close simultaneously.","metaTitle":"Siemens 3RH1131-1AC00-0TK2-ZX95 SIRIUS Auxiliary Contactor,","metaDescription":"Siemens SIRIUS auxiliary contactor 3RH1131-1AC00-0TK2-ZX95, 3 instantaneous NO contacts, size S00, IP20, screw/snap-on mount, active production.
