The CLASS 10 trip characteristic means the bimetal overload releases within 10 seconds at 600% of the set current, matching the thermal capacity of standard induction motors during a locked-rotor event. The operating voltage range spans 340 to 440 V AC, with a control supply rated 184–253 V at 50 Hz and 196–253 V at 60 Hz. The supply voltage type is AC throughout. ## Enclosure and mounting flexibility Rated IP55, the enclosure protects against dust ingress and low-pressure water jets — suitable for installation in industrial environments where washdown or airborne particulates are present. The unit measures 145 mm deep, 182 mm wide, and 220 mm high, fitting standard panel layouts with a vertical mounting surface.","metaTitle":"Siemens 3RK4353-3LR58-1BA0 SIRIUS Motor Starter, 6.3 A","metaDescription":"Siemens SIRIUS 3RK4353-3LR58-1BA0 reversing motor starter, 6.3 A at 400 V AC-3, CLASS 10 bimetal protection, IP55, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"145 mm","Width":"182 mm","title":"3RK4353-3LR58-1BA0","Height":"220 mm","Trip Class":"CLASS 10","description":"SIRIUS MCU motor starter Enclosure degree of protection IP55 plastic Communication without electromechanically switching Short-circuit protection with circuit breaker Reversing starter Brake without Performance class 6.3 A Motor circuit breaker with bi-metal thermal Manual operation latching Connection power M screw connection Electrical wholesale version","Type Of Voltage":"AC","lifecycle_stage":"current","Bus Communication":"No","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 controlled on site","protection class IP":"IP55","PROFIBUS DP protocol":"No","at 50 Hz rated value":"184 ... 253 V","at 60 Hz rated value":"196 ... 253 V","Design Of The Product":"reversing starter","Number Of Digital Inputs":"2","Short Circuit Protection":"Yes","at AC at 400 V rated value":"6.3 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":"No","brake control with 500 V DC":"No","Type Of The Motor Protection":"bimetal","at AC-3 at 400 V rated value":"6.3 A","Operating Voltage Rated Value":"340 ... 440 V","Substance Prohibitance (Date)":"05/01/2012","Design Of The Switching Contact":"electromechanical","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 ... +35 °C","Product Component Motor Brake Output":"No","Type Of Voltage Of The Supply Voltage":"AC","reference code according to IEC 81346-2":"Q","Number Of Poles For Main Current Circuit":"3","with low demand rate according to SN 31920":"50 %","protocol is supported AS-Interface protocol":"No","with high demand rate according to SN 31920":"75 %","operating power at AC-3 at 400 V rated value":"2.2 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","Supply Voltage Frequency For Auxiliary And Control Circuit Rated Value":"50 ... 60 Hz","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":"4.5 ... 6.3 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$393.70","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/35cca02686a864d29e85d1451830b702.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=510296&mlfb=3RK4353-3LR58-1BA0"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RK4353-3LR58-1BA0","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/3RK4353-3LR58-1BA0 when reusing this data.
