The contact reliability spec — one incorrect switching operation per 100 million operations at 17 V, 1 mA — means it also handles low-energy signals without the oxidation problems that plague general-purpose relays in dry circuits. Fastens with screw or snaps onto a DIN rail — both methods are supported. The 45 mm width and 114 mm depth fit the standard Size S00 footprint, so it drops into the same slot as other SIRIUS contactors and auxiliary blocks. Mounting position is flexible: ±180° rotation on a vertical surface, plus ±22.5° tilt forward or backward. Wire range is 0.25 to 2.5 mm² solid, which covers the common control-circuit sizes. Operating temperature range is -25 to +60 °C; storage and transport extend to -55 to +80 °C. Shock resistance is 10 g at 5 ms and 5 g at 10 ms. The part carries a RoHS substance prohibition date of July 1, 2006, indicating compliance with the original RoHS directive.","metaTitle":"Siemens 3RH1344-2CB00-0KA0-ZX95 SIRIUS Auxiliary Contactor,","metaDescription":"Siemens SIRIUS 3RH1344-2CB00-0KA0-ZX95 auxiliary contactor, Size S00, 4 NO contacts rated 10 A at 24 V.
