The unit operates on a 340... 460 V AC supply (50/60 Hz) and draws its control voltage from a 20.4... 26.4 V DC supply. Two digital inputs are available on the AS-Interface bus for local sensors or pushbuttons. The enclosure measures 205 mm deep, 290 mm wide, and 215 mm high — sized for a standard panel backplate. That range covers most cabinet layouts, including those with angled sub-panels. The product carries a substance prohibitance date of 05/01/2012 (RoHS compliance marker).","metaTitle":"Siemens 3RK4320-5PQ61-0BA2 SIRIUS Motor Starter","metaDescription":"Siemens SIRIUS 3RK4320-5PQ61-0BA2 motor starter for AS-Interface, solid-state motor protection, 12 A AC-3 at 400 V, IP54.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"205 mm","Width":"290 mm","Height":"215 mm","Trip Class":"CLASS 10","Type Of Voltage":"DC","lifecycle_stage":"current","Bus Communication":"Yes","Mounting Position":"+/-180° rotation possible on vertical mounting surface; can be tilted forward and backward by +/- 22.5° on vertical mounting surface","PROFINET protocol":"No","Product Brand Name":"SIRIUS","Type Of Assignment":"1","Product Designation":"motor starter MCU for AS-Interface","protection class IP":"IP54","PROFIBUS DP protocol":"No","Design Of The Product":"direct starter","Number Of Digital Inputs":"2","Short Circuit Protection":"Yes","at AC at 400 V rated value":"12 A","brake control with 24 V DC":"No","Operating Frequency Minimum":"3 600 1/h","brake control with 180 V DC":"No","brake control with 400 V AC":"No","brake control with 500 V DC":"No","Type Of The Motor Protection":"solid-state","at AC-3 at 400 V rated value":"12 A","Operating Voltage Rated Value":"340 ... 460 V","Substance Prohibitance (Date)":"05/01/2012","Design Of The Switching Contact":"solid-state","Operating Frequency 1 Rated Value":"50 Hz","Operating Frequency 2 Rated Value":"60 Hz","Design Of Short-Circuit Protection":"circuit-breakers","Ambient Temperature During Operation":"-25 ... +50 °C","Product Component Motor Brake Output":"Yes","Type Of Voltage Of The Supply Voltage":"DC","reference code according to IEC 81346-2":"Q","Number Of Poles For Main Current Circuit":"3","control supply voltage at DC rated value":"20.4 ... 26.4 V","with low demand rate according to SN 31920":"50 %","protocol is supported AS-Interface protocol":"Yes","with high demand rate according to SN 31920":"75 %","operating power at AC-3 at 400 V rated value":"5.5 kW","Product Extension Braking Module For Brake Control":"No","Relative Negative Tolerance Of The Operating Frequency":"-10 %","Relative Positive Tolerance Of The Operating Frequency":"10 %","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","breaking capacity maximum short-circuit current (Icu) at 400 V rated value":"50 000 A","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"3 ... 12 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=407641&mlfb=3RK4320-5PQ61-0BA2","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RK4320-5PQ61-0BA2/alternatives.json"},"ai":{"faq":[{"question":"What protection class does the 3RK4320-5PQ61-0BA2 have?","answer":"IP54 — dust-protected and splash-proof, suitable for indoor control panels but not for washdown or outdoor exposure."},{"question":"Does this motor starter support AS-Interface?","answer":"Yes, the AS-Interface protocol is supported, and the unit has two digital inputs on the bus."},{"question":"Where can I buy the 3RK4320-5PQ61-0BA2 motor starter?","answer":"This Siemens SIRIUS motor starter is available to order.
