The fixed Ir=125 A overload setting suits a dedicated 125 A feeder — no adjustment range, so the load must match that rating exactly. The Ii=10 x In fixed short-circuit setting provides a 1250 A magnetic trip threshold; this is typical for line protection of cable runs or non-motor loads where no high-inrush startup current is expected. The undervoltage release (UVR) at 24 V DC allows a safety circuit or emergency-stop chain to drop the breaker on loss of control voltage, common in machine-tool and conveyor guarding applications. On a panel swap or retrofit, having that hardware on the breaker saves a trip back to the van when the original nuts are rusted or missing.","metaTitle":"Siemens 3VA1112-5ED32-0BA0 Circuit Breaker, 125A, 55kA @ 415","metaDescription":"Siemens 3VA1112-5ED32-0BA0 circuit breaker, IEC frame 160, breaking capacity class M Icu=55kA @ 415V, 3-pole, line protection TM210, In=125A fixed overload Ir=125A, short-circuit I","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"lifecycle_stage":"current"}},"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=225641&mlfb=3VA1112-5ED32-0BA0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1112-5ED32-0BA0/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of this breaker?","answer":"The breaking capacity is Icu=55 kA at 415 V, class M, which is the standard interrupting rating for this frame size in industrial distribution panels."},{"question":"What does the undervoltage release do on this part?","answer":"The undervoltage release (UVR) trips the breaker when the 24 V DC control voltage drops below its dropout threshold, allowing integration with safety circuits or emergency-stop systems."},{"question":"Where can I buy 3VA1112-5ED32-0BA0 and get current pricing?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution channels.
