The enclosure is IP54, so it handles dust and splashing water in a washdown area or a non-conditioned cabinet — but it's not submersible. Mounting is flexible: the unit can be rotated ±180° on a vertical surface and tilted ±22.5° forward or backward, which helps when you're squeezing it into a crowded panel and the cable entry needs to face a specific direction. Dimensions are 290 mm wide, 215 mm high, 205 mm deep — allow clearance for the AS-Interface bus connector and the power wiring on the top and bottom. The control supply is 24 VDC nominal (20.4 to 26.4 V range), so it runs off a standard industrial PSU without a separate transformer. It includes a motor brake output (400 V AC) — if the connected motor has an AC brake coil, this starter can switch it directly, saving an external contactor. Two digital inputs are onboard for local pushbuttons or limit switches.","metaTitle":"Siemens 3RK4320-5PQ61-1BA3 SIRIUS Motor Starter, 12 A AC-3","metaDescription":"Siemens 3RK4320-5PQ61-1BA3 SIRIUS reversing motor starter, 12 A at 400 V AC-3, solid-state overload Class 10, AS-Interface bus, IP54.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"205 mm","Width":"290 mm","title":"3RK4320-5PQ61-1BA3","Height":"215 mm","Trip Class":"CLASS 10","description":"SIRIUS MCU motor starter Enclosure degree of protection IP54 metal Communication AS-Interface Electronic switching Short-circuit protection with circuit breaker Reversing starter Brake 400 V AC (internal) Performance class 12.00 A Motor protection electronic Overload relay with thermal motor model Manual operation without Connection power M screw connection Standard product","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":"Yes","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/cb927a19b190ddaad6c9fdc3a602258e.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=367069&mlfb=3RK4320-5PQ61-1BA3"},"ai":{"faq":[{"question":"What is the closest alternative to 3RK4320-5PQ61-1BA3 in the SIRIUS family?","answer":"The 3RK4320 series includes variants with different bus protocols (PROFIBUS, PROFINET) or without brake control, but those change the wiring and network integration.
