For a panel builder or site engineer, that level of SCCR headroom covers most industrial distribution boards fed from a transformer of 1,000 kVA or larger, and it simplifies coordination with downstream devices because the upstream breaker won't limit the let-through energy you need to calculate. ## Trip unit and protection settings The TM240 ATAM thermal-magnetic trip unit gives you an adjustable overload protection band from 280 A to 400 A (Ir), and a short-circuit pickup (Ii) adjustable from 5× to 10× In — so from 2,000 A to 4,000 A. ## Compliance and regulatory documentation RoHS compliant since 01-Nov-2017. The product family is the 3VA Molded Case Circuit Breakers up to 1600 A, IEC, which carries IEC 60947-2 certification — the standard that governs the 110 kA Icu rating and the thermal-magnetic trip performance.","metaTitle":"Siemens 3VA1340-7FF42-0AA0 MCCB, 400 A, 110 kA @ 415 V","metaDescription":"Siemens 3VA1340-7FF42-0AA0 IEC molded case circuit breaker, 400 A, 110 kA breaking capacity @ 415 V, TM240 ATAM trip unit, active production, quoted to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Group Code":"P360","Product Group":"5375","Product class":"C: products manufactured / produced to order, which cannot be reused or re-utilized or be returned against credit.","Quantity Unit":"1 Piece","Product Family":"3VA Molded Case Circuit Breakers up to 1600 A, IEC","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : N","Packaging dimensions (L x W x H)":"261.00 x 208.00 x 170.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 01-11-17","REACH Art. 33 Duty to inform according to the current list of candidates":"Lead CAS-No. 7439-92-1 > 0,1 % (w / w)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/f59d8c360c846d5ff9ef773daebb7908.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3VA1340-7FF42-0AA0?tree=CatalogTree","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1340-7FF42-0AA0/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for 3VA1340-7FF42-0AA0?","answer":"This part is made to order (product class C), so pricing and lead time are confirmed at quote time.
