Rated AC-12 at 10 A on 24 V, it handles the resistive control-circuit loads typical of relay coils and electronic inputs. At 230 V the rating drops to 6 A, and at 690 V to 1 A — the voltage derating curve matters if you're switching a 690 V control transformer secondary. Mechanical life is 10 million cycles typical, so it's built for high-duty applications like packaging lines or conveyor interlocks where the contactor cycles every few seconds. Side clearance is 0 mm, so you can gang them tight in a panel without derating for heat buildup. The 10 A AC-12 rating at 24 V is the maximum resistive current per contact. If you're switching inductive loads (contactors, solenoid valves), you'll need to derate — AC-15 or DC-13 ratings are what govern those, and they're lower. For a 24 VDC solenoid bank, stay under 1 A per contact unless you verify the DC switching capacity from the full datasheet. Shock resistance rated at 10g for 5 ms and 5g for 10 ms — enough for mounting on a machine frame or a vibrating conveyor section without contact bounce.","metaTitle":"Siemens SIRIUS 3RH1344-2AP00-0KA0 Auxiliary Contactor, S00,","metaDescription":"Siemens SIRIUS 3RH1344-2AP00-0KA0 auxiliary contactor, size S00, 4 NO instantaneous contacts, 45 mm width, IP20 front.
