Standing on a horizontal surface is the specified orientation. Terminals accept solid wire: two conductors at 0.5–1.5 mm², two at 0.75–2.5 mm², or two at 4 mm². That covers most control wiring gauges without needing ferrules, though stranded will want them. Those are the make-and-break capacities for pilot duty; don't plan on switching motor loads through these contacts. The 6 kV surge voltage rating (impulse withstand) means it coordinates with standard industrial control panels without extra suppression on the contact block itself. Contact reliability is specified as one incorrect switching operation per 100 million cycles at 17 V, 1 mA — that's the dry-circuit performance for low-level signals.","metaTitle":"Siemens 3RH1140-1AP00-1AA0-ZX95 SIRIUS Auxiliary Contactor,","metaDescription":"Siemens SIRIUS 3RH1140-1AP00-1AA0-ZX95 auxiliary contactor, size S00, 4 NO contacts, 10A at 24V.
