The thermal-magnetic trip unit provides both overload protection (thermal curve) and short-circuit protection (magnetic instantaneous trip set at 3500 A). Breaking capacity is 50 kA Icu at 380 V AC, 400-415 V AC, and 440 V AC per IEC 60947-2. At 220-240 V AC the Icu rises to 70 kA. Electrical durability is 4000 cycles at 415 V AC, mechanical durability 10,000 cycles. Mounts fixed to a backplate (not DIN rail) with front connections both top and bottom. IP20 finger-safe protection on the front; IK07 impact rating means it withstands a 2 J hammer blow — fine for general industrial enclosures. Pollution degree 3 per IEC 60947, so it's rated for conductive environments (condensation, light dust). Physical footprint: 255 mm high, 185 mm wide, 140 mm deep. Connection pitch (pole spacing) is 44 mm. The breaker uses a toggle handle for manual control and provides positive contact indication — the handle position mechanically reflects the contact state, not a separate flag. No earth-leakage protection module is integrated; neutral protection is not provided (3-pole, no neutral pole). If ground-fault or neutral protection is required, an external add-on must be wired downstream. Standards compliance includes IEC 60947-2, EN 60947-2, JIS C8201-2-2, and GB/T 14048.2. No UL or CSA listing is stated in the record.","metaTitle":"Schneider Electric EZC400H3400 EasyPact EZC400H, 400 A, 50 k","metaDescription":"Schneider Electric EZC400H3400 EasyPact EZC400H circuit breaker, 400 A rated at 50 °C, 50 kA Icu at 380-440 V AC, IEC 60947-2, active production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"140 mm","Width":"185 mm","Colour":"Black","Height":"255 mm","Standards":"JIS C8201-2-2 EN/IEC 60947-1 GB/T 14048.2 EN/IEC 60947-2","Control type":"Toggle","Network type":"AC","Mounting mode":"Fixed","Trip unit name":"TM-D","Protection type":"Short-circuit protection Overload protection","lifecycle_stage":"current","Connection pitch":"44 mm","Local signalling":"Positive contact indication","Mounting support":"Backplate","Pollution degree":"3 conforming to IEC 60947","Quantity per set":"1 piece","Range of product":"EasyPact","Trip unit rating":"400 A at 50 °C","Breaking capacity":"50 kA Icu at 380 V AC 50/60 Hz conforming to IEC 60947-2 50 kA Icu at 400...415 V AC 50/60 Hz conforming to IEC 60947-2 50 kA Icu at 440 V AC 50/60 Hz conforming to IEC 60947-2 70 kA Icu at 220...240 V AC 50/60 Hz conforming to IEC 60947-2","Device short name":"Easypact EZC400H","Network frequency":"50/60 Hz","Poles description":"3P","Upside connection":"Front","Device application":"Distribution","[In] rated current":"400 A at 40 °C","Downside connection":"Front","Circuit breaker name":"Easypact EZC400H","Trip unit technology":"Thermal-magnetic","Utilisation category":"Category A","Electrical durability":"Category A: 4000 cycles 415 V AC 50/60 Hz conforming to IEC 60947-2","Mechanical durability":"10000 cycles","Breaking capacity code":"H","IK degree of protection":"IK07 conforming to EN 50102","IP degree of protection":"IP20 conforming to IEC 60529","Earth-leakage protection":"Without","Magnetic tripping current":"3500 A","Product or component type":"Circuit breaker","Suitability for isolation":"Yes conforming to IEC 60947-2","Contact position indicator":"Yes","Neutral protection setting":"Without protection","Protected poles description":"3t","[Ui] rated insulation voltage":"690 V AC 50/60 Hz conforming to IEC 60947-2","[Ue] rated operational voltage":"440 V AC 50/60 Hz conforming to IEC 60947-2","Long time delay adjustment type":"Fixed","Ambient air temperature for storage":"-35...85 °C","Long time pick-up adjustment type Ir":"Fixed","Ambient air temperature for operation":"-25...70 °C","[Ics] rated service breaking capacity":"25 kA at 380 V AC 50/60 Hz conforming to IEC 60947-2 25 kA at 400/415 V AC 50/60 Hz conforming to IEC 60947-2 25 kA at 440 V AC 50/60 Hz conforming to IEC 60947-2 35 kA at 220/230 V AC 50/60 Hz conforming to IEC 60947-2","[Uimp] rated impulse withstand voltage":"8 kV conforming to IEC 60947-2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c8f370832684220ea0517200de97e6a4.pdf","sourceUrl":"https://www.se.com/ph/en/product/EZC400H3400/circuit-breaker-easypact-ezc400h-tmd-400-a-3-poles-3d/","alternativesUrl":"https://aoctrl.com/api/mcp/products/EZC400H3400/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/EZC400H3400","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/EZC400H3400 when reusing this data.
