Rated operational currents span 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — these are the thermal (AC-1) or utilization-category values that govern the actual load it can switch, not just a single headline number. The coil accepts 0.8...1.1 times its rated voltage at both 50 Hz and 60 Hz, so it holds in on a weak supply and drops out reliably on undervoltage. ## Contact reliability and mechanical life Contact reliability is specified at one incorrect switching operation per 100 million cycles at 17 V, 1 mA — that is the low-energy dry-circuit performance that matters for PLC inputs and signal-level loads where oxide films on silver contacts can cause intermittent opens. Shock resistance is 10g for 5 ms and 5g for 10 ms, adequate for machine-mounted panels on conveyors or packaging equipment. Screw terminals accept solid conductors: 2x 0.5...1.5 mm², 2x 0.75...2.5 mm², or 2x 4 mm². The dual-wire capacity per clamp is useful when daisy-chaining control voltage to multiple contactors in a motor control center — one wire in, one wire out under the same screw saves a terminal block.","metaTitle":"Siemens 3RH1131-1AF00-0TK1-ZX95 SIRIUS Auxiliary Contactor,","metaDescription":"Siemens SIRIUS 3RH1131-1AF00-0TK1-ZX95 auxiliary contactor, 3 NO contacts, size S00, 45 mm wide.
