It carries 4 NO instantaneous contacts rated to switch 10 A at 24 V, 6 A at 230 V, or 3 A at 400 V, covering the common control voltages found in 50/60 Hz panels. The contactor mounts via screw or snap-on onto a 35 mm DIN rail. The mounting position is flexible: ±180° rotation on a vertical surface, and ±22.5° tilt forward/backward — useful when fitting into tight gland-plate areas or angled sub-panels. ## Switching ratings and what they mean for your control circuit The 4 NO contacts are rated for AC-15 and DC-13 loads typical of solenoid and relay coils. At 24 V DC the contact carries 10 A; at 220 V DC it carries 1.2 A. The arcing time is 10–15 ms, and the mechanical life is 10 million operations — a solid figure for a control-circuit component that sees frequent cycling in a packaging or conveyor line. Clearance and creepage distances follow pollution degree 3, so the contactor is suited for industrial environments where conductive dust or condensation is present. The operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C. ## Lifecycle and sourcing reality The 3RH2244-4AP60 is sourced to order against the BOM through authorized distribution.","metaTitle":"Siemens 3RH2244-4AP60 SIRIUS Auxiliary Contactor, 4 NO","metaDescription":"Siemens 3RH2244-4AP60 SIRIUS auxiliary contactor, 4 NO contacts, Size S00, 10 A at 24 V, screw and snap-on 35 mm DIN rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"117 mm","Width":"45 mm","at AC":"4 ... 15 ms","at DC":"10 000 1/h","title":"3RH2244-4AP60","Height":"57.5 mm","Upwards":"10 mm","Forwards":"10 mm","at 50 Hz":"0.8 ... 1.1","at 60 Hz":"0.85 ... 1.1","Downwards":"10 mm","Arcing Time":"10 ... 15 ms","At The Side":"6 mm","description":"contactor relay, 4 NO + 4 NC, 220 V AC, 50 Hz, 240 V, 60 Hz, size S00, ring cable lug connection, captive auxiliary switch","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","During Storage":"-55 ... +80 °C","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail","Mounting Position":"+/-180° rotation possible on vertical mounting surface; can be tilted forward and backward by +/- 22.5° on vertical mounting surface","Size Of Contactor":"S00","Product Brand Name":"SIRIUS","Degree Of Pollution":"3","Product Designation":"Auxiliary contactor","at 24 V rated value":"10 A","at 60 V rated value":"4.7 A","Of Contactor Typical":"10 000 000","at 110 V rated value":"3 A","at 220 V rated value":"1.2 A","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 440 V rated value":"0.5 A","at 50 Hz rated value":"220 V","at 500 V rated value":"2 A","at 60 Hz rated value":"240 V","at 600 V rated value":"0.26 A","at 690 V rated value":"1 A","Instantaneous Contact":"4","Relative Humidity Minimum":"10 %","Substance Prohibitance (Date)":"10/01/2009","Product Extension Auxiliary Switch":"No","Surge Voltage Resistance Rated Value":"6 kV","operating frequency at DC-12 maximum":"1 000 1/h","operating frequency at DC-13 maximum":"1 000 1/h","operational current at AC-12 maximum":"10 A","reference code according to IEC 81346-2":"K","Contact Reliability Of Auxiliary Contacts":"1 faulty switching per 100 million (17 V, 1 mA)","with low demand rate according to SN 31920":"40 %","apparent holding power of magnet coil at AC":"5.7 VA","apparent pick-up power of magnet coil at AC":"37 VA","with high demand rate according to SN 31920":"73 %","number of NC contacts for auxiliary contacts":"4","number of NO contacts for auxiliary contacts":"4","Type Of Voltage Of The Control Supply Voltage":"AC","contact rating of auxiliary contacts according to UL":"A600 / Q600","Inductive Power Factor With Closing Power Of The Coil":"0.8","Identification Number And Letter For Switching Elements":"44 E","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Inductive Power Factor With The Holding Power Of The Coil":"0.25","Type Of Electrical Connection For Auxiliary And Control Circuit":"ring terminal lug connection","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Design Of The Fuse Link For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A","design of the miniature circuit breaker for short-circuit protection of the auxiliary circuit up to 230 V":"C characteristic: 6 A; 0.4 kA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/ecf32d16a8309ac64507aef0576f7964.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=38419&mlfb=3RH2244-4AP60"},"ai":{"faq":[{"question":"What is the 3RH2244-4AP60 used for?","answer":"It's an auxiliary contactor with 4 NO contacts, used to switch control circuits — relay coils, PLC inputs, solenoid valves — in industrial panels.
