It is designed for control-circuit switching — signaling, interlocking, or extending the contact count of a main contactor or starter in a panel. The 45 mm width and 57.5 mm height fit the S00 footprint, and the 111 mm depth leaves clearance for wiring in shallow enclosures. Rated for 10 A at 24 V and 6 A at 230 V, with a surge voltage resistance of 6 kV, this contactor handles typical 24 VDC and 230 VAC control circuits in industrial panels. The 4 NO contacts are all instantaneous — no leading, lagging, or delayed switching — so it is a straightforward signal repeater, not a timing element. Fastens by screw and snap-on mounting onto a DIN rail. Solid wire terminations accept 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), and 2x 4 mm². That covers most control-circuit wiring from signal-level to moderate power. Compliance documentation includes a substance prohibition date of 07/01/2006, aligning with RoHS and REACH requirements. The contact reliability spec — one incorrect switching operation per 100 million at 17 V, 1 mA — confirms it is suitable for low-energy signal circuits where contact oxidation can be a problem. Shock resistance is 10g / 5 ms and 5g / 10 ms. The 50/60 Hz rated operating range (0.8... 1.1 at 50 Hz, 0.85... 1.1 at 60 Hz) at 380 V covers global line frequencies without derating.","metaTitle":"Siemens 3RH1344-1AQ00-ZX95 SIRIUS Auxiliary Contactor, 4 NO,","metaDescription":"Siemens SIRIUS 3RH1344-1AQ00-ZX95 auxiliary contactor, size S00, 4 instantaneous NO contacts.
