Rated for 10 A at 24 V and 6 A at 230 V, with a 6 kV surge voltage withstand, it handles the control-circuit switching in a 400 V panel without issue. Mounts via screw or snap-on to a DIN rail. Screw terminals accept 2x 4 mm² solid or 2x 1.5 mm² stranded — no ferrule crimping required for the larger wire, but the spring pressure is set for the listed cross-sections. Four NO contacts rated for 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. The 50/60 Hz coil tolerance is 0.8 to 1.1 times rated voltage at 50 Hz, 0.85 to 1.1 at 60 Hz. Contact reliability is specified at one incorrect switching operation per 100 million cycles at 17 V, 1 mA — that's the low-energy switching figure that matters for PLC inputs or dry-contact signals. Shock resistance is 10g at 5 ms and 5g at 10 ms, so it holds in high-vibration environments like compressor skids or conveyor drives. RoHS compliance date listed as July 1, 2006 — the part is fully RoHS-compliant.","metaTitle":"Siemens 3RH1140-1AP00-0AA6 SIRIUS Auxiliary Contactor, 4 NO,","metaDescription":"Siemens SIRIUS auxiliary contactor 3RH1140-1AP00-0AA6, 4 NO contacts, size S00, 45mm wide, IP20 front. 10A at 24V, 6kV surge rated.
