The 6 kV rated surge voltage withstand gives it solid isolation coordination for industrial panels with mixed voltage levels. Contact reliability is specified at one incorrect switching operation per 100 million cycles at 17 V, 1 mA — that's the low-energy signal switching threshold. If you're dry-switching PLC-level signals, this contactor handles it without the contact wetting issues you'd see on a standard power contactor. Terminals accept solid conductors from 0.5 mm² up to 4 mm² (or 2x 1.5 mm², 2x 2.5 mm²), with AWG equivalents of 20–16, 18–14, and a single 12 AWG.","metaTitle":"Siemens 3RH1122-1AH10 SIRIUS Auxiliary Contactor, 10A AC-12,","metaDescription":"Siemens SIRIUS 3RH1122-1AH10 auxiliary contactor, size S00. 10A AC-12, 2 NO + 2 NC contacts.
