It measures active and reactive energy, power, current, voltage and power factor to IEC 61557-12, and relays the readings over its built-in 2.4 GHz radio to a PowerTag-compatible concentrator or gateway for circuit-level monitoring.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLV434021\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\u003ePowerLogic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePowerTag M250\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\u003eEnergy sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNumber of poles \/ network type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3P + N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaximum current (Imax)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e250 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBasic current (Ib)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e40 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStarting current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e160 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSaturation current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e500 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMeasured values\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eActive and reactive energy, active\/reactive\/apparent power, current, voltage, power factor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAccuracy class\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eClass 1 current and active energy, Class 2 reactive energy, conforming to IEC 61557-12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting location \/ support\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBottom, on circuit breaker\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnection pitch\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e35 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible breaker ranges\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCompact NSX 100\/160\/250, Compact NS 100\/160\/250, Compact INS250, and Compact INV 100\/160\/200\/250\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWireless protocol\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.4...2.4835 GHz radio frequency conforming to IEEE 802.15.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEmission power\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSupply voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e230 V AC +\/- 20% phase-to-neutral, 400 V AC +\/- 20% phase-to-phase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaximum power consumption\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.7 VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions (H x W x D)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e57 mm x 140 mm x 86 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e300 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIP \/ IK degree of protection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIP20 \/ IK07\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmbient air temperature for operation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-25...70 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp;

The added neutral conductor on this 3P + N variant is needed when the circuit's neutral current or neutral-referenced energy must be measured separately, such as on a TN-S distribution feeding unbalanced single-phase loads off a three-phase-plus-neutral breaker. The basic current (Ib) of 40 A sets the lower bound for accurate Class 1 metering; below that, readings fall outside the IEC 61557-12 accuracy class.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54080600572187,"sku":"LV434021","price":504.07,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-lv434021-powertag-nsx-energy-m250.jpg?v=1790934932","url":"https:\/\/stoklink.com\/products\/schneider-electric-lv434021-powertag-nsx-energy-m250","provider":"Stoklink","version":"1.0","type":"link"}
