It provides LSI protection (long-time, short-time, instantaneous) plus integrated energy metering and power quality monitoring, displayed on an LCD screen. The trip unit carries UL 508 and EN/IEC 60947-2 certifications, with marine, CCC, and EAC approvals. Zone selective interlocking (ZSI) is built in for coordinated tripping in multi-tier distribution. The long-time pickup Ir is field-adjustable from 250 to 630 A, with a delay Tr adjustable 15 to 400 s at 1.5 x Ir. Short-time pickup Isd offers 9 settings, with delay Tsd adjustable 0 to 0.4 s and I²t on/off. This range suits feeder and main breaker applications where coordination with downstream devices is required. Thermal memory retains 20 minutes of thermal history before and after tripping, improving coordination on repeated overloads. Compared to the LV432106 (MicroLogic 5.3 A, 400 A, 4 poles), the LV432089 offers a higher 630 A rating and 3 poles. The LV432106 is a 4-pole unit at 400 A, making the LV432089 the correct choice for 3-pole 630 A feeders where the fourth pole is not needed.","metaTitle":"Schneider LV432089 MicroLogic 5.3 A-Z trip unit, 630 A, 3-pole","metaDescription":"Schneider LV432089 MicroLogic 5.3 A-Z electronic trip unit for ComPact NSX 630, 630 A, 3 poles, LSI protection, energy metering, LCD display, UL 508, IEC 60947-2.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Range":"ComPact","Category":"US10DE201101","Standards":"UL 508 EN/IEC 60947-2","Display Type":"LCD display","Network type":"AC","Thermal memory":"20 minutes before and after tripping","Trip unit name":"MicroLogic 5.3 A-Z","Number of poles":"3P","Protection type":"L : for overload protection (long time) S : for short time short-circuit protection I : for instantaneous short-circuit protection","lifecycle_stage":"mature","Local signalling":"Flashing LED (green) for ready to operate LED 105 % Ir (red) for overload LED 90 % Ir (orange) for overload","Range of Product":"ComPact NSX400...630","Network Frequency":"50/60 Hz","Device Application":"Special application","Type of Measurement":"Ammeter","Trip unit technology":"Electronic","Communication of data":"Energy metering Power quality Maximeters/minimeters Time-stamped histories and event tables Maintenance indicators Protection and alarm settings Demand current and power Instantaneous and demand values","Nbr. of units in pkg.":"1","Trip unit rated current":"630 A 104 °F (40 °C)","Earth-leakage protection":"Without","Electrical data recording":"Maintenance indicators","Product or Component Type":"Trip unit","Protected poles description":"3t","Trip unit protection functions":"LSI","[Ue] rated operational voltage":"690 V AC 50/60 Hz","Zone selective interlocking ZSI":"With","Ambient Air Temperature for Storage":"-40...185 °F (-40...85 °C)","Ambient Air Temperature for Operation":"-13...158 °F (-25...70 °C)","Long-time protection delay adjustment type tr":"Adjustable","Short-time protection delay adjustment type tsd":"Adjustable","[Tr] Long-Time Protection Delay Adjustment Range":"15...400 s 1.5 x Ir 0.35...11 s 7.2 x Ir 0.5...16 s 6 x Ir","Short-time protection pick-up adjustment type Isd":"Adjustable 9 settings","[Ir] long-time protection pick-up adjustment range":"250...630 A","[tsd] Short-time protection delay adjustment range":"0...0.4 s I²t=off 0.1...0.4 s I²t=on","Instantaneous protection pick-up adjustment type Ii":"Adjustable","[Isd] Short-time protection pick-up adjustment range":"1.5...10 x Ir","[Ii] instantaneous protection pick-up adjustment range":"1.5...11 x In","Long-time pick-up adjustment type Ir (thermal protection)":"Adjustable 9 settings"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,835.14","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/7a69e327b517a7a4c1b4528c6834960d.pdf","sourceUrl":"https://www.se.com/au/en/product/LV432089/trip-unit-micrologic-5-3-az-for-compact-nsx-630-circuit-breakers-electronic-rating-630-a-3-poles-3d/","alternativesUrl":"https://aoctrl.com/api/mcp/products/LV432089/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LV432089","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/LV432089 when reusing this data.
