The operating voltage range is 340...460 V. The control supply is 20.4...26.4 V DC. Two digital inputs are onboard. This reversing starter measures 205 mm deep, 290 mm wide, and 215 mm tall. It mounts on a vertical surface with ±180° rotation possible and can tilt forward/backward ±22.5° — useful for tight panel layouts where straight-on access is limited. IP54 protection means it is dust-protected and splash-resistant, suitable for dry indoor control panels or light industrial environments where occasional dust or water spray is present. Operating ambient temperature spans -25 to +50 °C. ## Bus integration and protocol AS-Interface is the sole fieldbus on this unit (PROFINET and PROFIBUS DP are not supported). The AS-Interface protocol is supported for communication, making this a drop-in node on an AS-i network for motor control. With low-demand rate per SN 31920 at 50% and high-demand rate at 75%, the unit is designed for operational frequencies up to 3,600 operations per hour.","metaTitle":"Siemens 3RK4320-5PQ61-1BA2 SIRIUS MCU Reversing Starter","metaDescription":"Siemens SIRIUS 3RK4320-5PQ61-1BA2 motor starter MCU for AS-Interface, reversing starter, solid-state motor protection, Trip Class 10, 12 A at AC-3 400 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":"reversing 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=29178&mlfb=3RK4320-5PQ61-1BA2","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RK4320-5PQ61-1BA2/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3RK4320-5PQ61-1BA2 online?","answer":"This part is sourced to order.
