The AC-12 maximum operating current of 10 A covers the typical control load: contactor coils, relays, and PLC inputs on 24 VDC or 110 VAC. The 6 kV surge voltage resistance means it handles the transients common on industrial control panels without external suppression in most cases. Mounts by screw or snaps onto a DIN rail. The 45 mm width and 60 mm height are the S00 footprint — it occupies one standard 45 mm module on the rail, leaving room for the power contactor beside it. Depth of 114 mm means the coil terminals and auxiliary wiring project about 4.5 inches into the enclosure; plan the gland plate and wireway clearance accordingly. Wire termination accepts 2x (0.25... 2.5 mm²) solid or stranded — standard control wire sizes, no ferrule restriction. Shock resistance is 10g at 5 ms and 5g at 10 ms — adequate for machine-mounted panels near presses or conveyors.","metaTitle":"Siemens 3RH1344-2AG10 SIRIUS Auxiliary Contactor, 4 NO, S00,","metaDescription":"Siemens 3RH1344-2AG10 SIRIUS auxiliary contactor, size S00, 4 NO contacts, rated 10 A at AC-12, 24 V.
