That fixed setting simplifies ordering: no adjustment dials to mis-set on site, but also no field flexibility — the breaker is locked to its 40 A rating, so the load must match exactly. The N conductor is unprotected (solid neutral), and the breaker includes a nut keeper kit — a detail that speeds DIN-rail or mounting-plate installation in OEM panel builds, especially for the DC Power OEM channel in China this variant targets. The 4-pole format occupies four module widths; plan for adequate heat dissipation if grouping multiple breakers in a sealed enclosure — the TM210 trip curve assumes free-air ambient at 40 °C.","metaTitle":"Siemens 3VA1040-4ED42-0AA0-ZD00 Circuit Breaker, 40A, 36kA @","metaDescription":"Siemens 3VA1040-4ED42-0AA0-ZD00 IEC frame 100 circuit breaker, 40A, 36kA breaking capacity at 415V, 4-pole, TM210, FTFM, current lifecycle stage, available to order.","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=1667482&mlfb=3VA1040-4ED42-0AA0-ZD00","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1040-4ED42-0AA0-ZD00/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of this breaker?","answer":"The breaking capacity is 36 kA at 415 V (class S), which is the maximum fault current it can safely interrupt."},{"question":"Where can I buy 3VA1040-4ED42-0AA0-ZD00?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1040-4ED42-0AA0-ZD00","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/3VA1040-4ED42-0AA0-ZD00 when reusing this data.
