The 10 A AC-12 rating at 24 V is the maximum continuous resistive current each contact can carry. For inductive loads like small contactor coils or solenoid valves, you'll need to derate — the evidence shows 1 A at 110 V and 0.27 A at 220 V, so the inductive curve drops fast as voltage climbs. That's plenty for most signal-following applications; you won't wear it out before the main contactor it's riding with. The solid connection accepts 2x conductors from 0.25 to 2.5 mm², so you can loop through one contact to feed the next device without a separate terminal block. Depth of 114 mm leaves room behind the DIN rail for wiring troughs. That covers most panel layouts and angled subplates. Screw and snap-on mounting means you can pre-wire it on the bench and snap it onto the rail, or screw it directly to a backplate if the rail is full. Height is 60 mm, depth 114 mm — it won't overhang a standard 100 mm deep enclosure, but check your door clearance if the panel is shallow.","metaTitle":"Siemens 3RH1344-2AF00-ZX95 SIRIUS Auxiliary Contactor, 4 NO,","metaDescription":"Siemens SIRIUS 3RH1344-2AF00-ZX95 auxiliary contactor, Size S00, 4 NO instantaneous contacts, 10 A at 24 V AC-12, IP20 front, screw/snap-on mount.
