It is fitted with an auxiliary switch (normally open) for remote monitoring of the main contact position.\u003c\/p\u003e\n\u003cp\u003eEpoxy sealed and nitrogen-filled for a hermetically sealed contact chamber, the EVD50G12DA2 is designed for demanding DC switching duties in EV, battery storage, and industrial power systems. The single pole, normally open main contacts are non-polarised, so the contactor can be wired without regard to current direction, and are suitable for interrupted and continuous switching of resistive, inductive, and capacitive loads. The 12V coil is continuously rated, giving reliable, sustained operation without the need for a PWM economiser circuit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSingle pole, single throw, normally open main contacts rated at \u003cstrong\u003e50A continuous\u003c\/strong\u003e (max breaking current \u003cstrong\u003e1000A at 320V DC\u003c\/strong\u003e, single operation)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12V DC continuously-rated coil\u003c\/strong\u003e, drawing approximately \u003cstrong\u003e5.5W\u003c\/strong\u003e coil holding power\u003c\/li\u003e\n\u003cli\u003eAuxiliary switch fitted — \u003cstrong\u003enormally open\u003c\/strong\u003e contact for main-contact status monitoring\u003c\/li\u003e\n\u003cli\u003eContact resistance of \u003cstrong\u003e≤1mΩ at 50A\u003c\/strong\u003e, initial insulation resistance of \u003cstrong\u003e1000MΩ\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eEpoxy sealed, nitrogen-filled contact chamber for long service life in harsh environments\u003c\/li\u003e\n\u003cli\u003eMechanical life rated at \u003cstrong\u003e3×10⁵ cycles\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of \u003cstrong\u003e-40°C to +85°C\u003c\/strong\u003e, altitude to \u003cstrong\u003e4000m\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eTested to \u003cstrong\u003eEN 60947-4-1\u003c\/strong\u003e, CE marked with EU Declaration of Conformity available\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eApplications include:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEV and HV battery isolation and main contactor duty\u003c\/li\u003e\n\u003cli\u003eBattery pack switching for e-mobility and energy storage systems\u003c\/li\u003e\n\u003cli\u003eMarine and aviation power systems\u003c\/li\u003e\n\u003cli\u003eRobotics and autonomous vehicle platforms\u003c\/li\u003e\n\u003cli\u003eAgricultural and low-volume OEM machinery\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Estar","offers":[{"title":"Default","offer_id":54097975574875,"sku":"HEI.001.016.054","price":27.97,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/9218\/1595\/files\/Website1000x1000imageEVD50G24DA2.png?v=1789593832","url":"https:\/\/www.heinfusion.com\/products\/estar-evd50g12da2-12v-contactor-aux-normally-open-continuous-duty","provider":"HE Infusion UK","version":"1.0","type":"link"}
