Control supply is 20.4–26.4 V DC, and the unit draws its logic power from the AS-Interface bus. Two digital inputs are available for local start/stop or interlock signals. The enclosure is IP54 — fine for dry factory-floor cabinets but not for washdown zones. Dimensions are 205 mm deep, 290 mm wide, 215 mm high; plan the DIN-rail or screw-mount footprint accordingly.","metaTitle":"Siemens 3RK4422-4PQ67-0BB3 SIRIUS MCU Motor Starter, 12 A","metaDescription":"Siemens 3RK4422-4PQ67-0BB3 SIRIUS MCU motor starter with soft starter and AS-interface. 12 A at 400 V AC-3, 5.5 kW, CLASS 10, IP54.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Soft Starters"],"specifications":{"Depth":"205 mm","Width":"290 mm","title":"3RK4422-4PQ67-0BB3","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 Soft starter Brake 400 V AC (internal) Performance class 12.00 A Motor circuit breaker with temperature sensor Rotary operating mechanism gray/black Connection power M screw connection customized Design Airport Dublin","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":"MCU motor starter, soft starter with AS-interface","protection class IP":"IP54","PROFIBUS DP protocol":"No","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":"80 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":"full motor protection","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 / thyristor / 2 phases","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","maximum short-circuit current breaking capacity (Icu) at 400 V rated value":"50 000 A","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"11 ... 16 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d687c9fa74b5b3c96133ad3b3563f771.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=132037&mlfb=3RK4422-4PQ67-0BB3"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RK4422-4PQ67-0BB3","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RK4422-4PQ67-0BB3 when reusing this data.
