It is a 3-pole unit for DC distribution, fixed long-time and short-time delays, and carries certifications including ASTA, KEMA, LCIE, and ASEFA. Schneider discontinued the LV438245 on 2023-06-15; it is no longer in active production and must be sourced through surplus or broker channels. Compared to the LV438246, the LV438245 switches 250 A versus 200 A, both at 750 V DC with 3 poles and the same TM-D trip unit; choose the LV438245 when the load requires the higher 250 A rating.","metaTitle":"Schneider LV438245 TM250DC trip unit, 250 A, 3-pole, DC","metaDescription":"Schneider LV438245 TM250DC thermal-magnetic trip unit for ComPact NSX250 DC, 250 A, 3-pole, 750 V DC, IEC 60947-2, discontinued since 2023-06-15.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Range":"ComPact","Standards":"IEC 60947-2","Network type":"DC","Trip unit name":"TM-D","Number of poles":"3P","Protection type":"L : for overload protection (thermal) I : for short-circuit protection (magnetic)","lifecycle_stage":"mature","Range of product":"ComPact NSX100...250 DC","Device application":"Distribution","Trip unit technology":"Thermal-magnetic","Trip unit rated current":"250 A at 40 °C","Earth-leakage protection":"Without","Product or component type":"Trip unit","Protected poles description":"3t","Trip unit protection functions":"LI","[Ue] rated operational voltage":"750 V DC","Ambient air temperature for storage":"-50...85 °C","Ambient air temperature for operation":"-25...70 °C","Long-time protection delay adjustment type tr":"Fixed","Short-time protection delay adjustment type tsd":"Fixed","Short-time protection pick-up adjustment type Isd":"Adjustable","[Ir] long-time protection pick-up adjustment range":"0.7...1 x In","[Isd] Short-time protection pick-up adjustment range":"5...10 x In","Long-time pick-up adjustment type Ir (thermal protection)":"Adjustable"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$172.48 – $220.51","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/731144fb8fefeeb32d42edb714dd99be.pdf","sourceUrl":"https://www.se.com/vn/en/product/LV438245/trip-unit-tm250dc-compact-nsx-250-dc-thermal-magnetic-250-a-rating-3p-3d/","alternativesUrl":"https://aoctrl.com/api/mcp/products/LV438245/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LV438245","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/LV438245 when reusing this data.
