It opens the breaker automatically once the supervised voltage falls to 0.35-0.7 Un, then re-closes the circuit once voltage recovers to 0.85 Un.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eReference\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLV847385\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMasterPact\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDevice short name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct or Component Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUndervoltage release\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDevice Application\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSafety\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRange compatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMasterPact MTZ1, MTZ2, MTZ3 circuit breaker\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVoltage release type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eInstantaneous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eControl Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStandard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Un] voltage power supply\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e380-480 V AC 50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThreshold tripping voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.35-0.7 Un opening, 0.85 Un closing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHolding power consumption\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4.5 VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCircuit breaker mounting mode\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFixed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaximum response time\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e45 ms on MTZ1, 95 ms on MTZ2, 95 ms on MTZ3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eThe LV847385 is the AC-only, 380-480 V member of the MN family and has no DC rating, unlike the 100-130 V and 200-250 V versions that accept either AC or DC supply; confirm the control source is AC before specifying it. It fits fixed MTZ1, MTZ2, and MTZ3 breakers only. Because the trip threshold is 0.35-0.7 Un, it reacts well before a complete loss of control voltage, giving the downstream load an early, controlled disconnect rather than an uncontrolled one. Holding power consumption is specified in VA rather than W for this AC-only variant, reflecting the reactive component of the coil's steady-state draw.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54078777000219,"sku":"LV847385","price":204.24,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-lv847385-mn-undervoltage-release-air-circuit-breaker-accessory.jpg?v=1790907715","url":"https:\/\/stoklink.com\/products\/schneider-electric-lv847385-mn-undervoltage-release","provider":"Stoklink","version":"1.0","type":"link"}
