Depth is 111 mm, width 45 mm, height 57.5 mm, so it fits the standard S00 footprint used across the SIRIUS 3RH1 family. The 10 A at 24 V rating is the DC-13 (solenoid/contact coil) load capability — it handles the inrush of a small contactor or relay coil without welding the contacts. The 6 A at 230 V and 3 A at 400 V are AC-15 (control circuit) ratings, so this contactor is sized for switching PLC outputs, pilot lights, and solenoid valves in a 230 V or 400 V control panel. The four NO contacts are all instantaneous — no delayed, leading, or lagging switching — so it's a straight signal repeater, not a timing element. ## Mounting and wiring flexibility The solid wire range accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² — enough for control wiring up to 4 mm² stranded or solid without ferrules. Same part, different passport — genuine Siemens regardless of which authorized region it originated from. Let me be transparent: the manufacturer warranty may be region-locked, but the part itself is identical to what you'd get from any Siemens channel.","metaTitle":"Siemens 3RH1344-1AM20-0KA0 SIRIUS Auxiliary Contactor, 4 NO,","metaDescription":"Siemens SIRIUS auxiliary contactor 3RH1344-1AM20-0KA0, size S00, 4 instantaneous NO contacts, screw/snap-on mount, IP20 front.
