It trips the breaker instantaneously once the supervised voltage drops to 0.35-0.7 Un, giving the connected MasterPacT breaker an undervoltage safety trip and re-closing permission 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\u003eLV947385\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 Active, MasterPacT MTZ2 Active, MasterPacT MTZ3 Active circuit breakers\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\u003eMaximum response time on opening\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e45 ms (MasterPacT MTZ1), 95 ms (MasterPacT MTZ2), 95 ms (MasterPacT MTZ3)\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\u003eNumber of units in package\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eThe MN release is an undervoltage trip, not an overcurrent protection: it opens the breaker when the supervised voltage falls below the 0.35-0.7 Un threshold and re-closes above 0.85 Un, so it is specified for safety interlocking rather than fault clearing. It fits the fixed-mounting MasterPacT MTZ1, MTZ2 and MTZ3 Active breakers only; the drawout version of the same breakers needs the corresponding drawout-rated release. The 380-480 V AC supply range covers both 50 Hz and 60 Hz installations without a separate part number.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54078640881947,"sku":"LV947385","price":173.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-lv947385-mn-undervoltage-release.jpg?v=1790904711","url":"https:\/\/stoklink.com\/products\/schneider-electric-lv947385-mn-undervoltage-release","provider":"Stoklink","version":"1.0","type":"link"}
