With a rated current of 40A and a voltage capacity of 500V DC, this component provides essential overcurrent protection for power conversion equipment, battery management systems, and high-voltage auxiliary power distribution units (PDU).\u003c\/p\u003e\n\u003cp\u003eThe EV315 series is engineered to perform reliably under the harsh environmental conditions of the automotive industry, including significant mechanical shock, continuous vibration, and extreme temperature thermal cycling. Its fast-acting characteristic ensures low let-through energy (I²t) and peak current limitation, effectively shielding sensitive power electronics from catastrophic fault currents. The 3EN bolt-on terminal design provides a robust, low-impedance mechanical interface, ensuring stable electrical performance throughout the vehicle's lifecycle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSinofuse (Xi'an Sinofuse Electric Co., Ltd.)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEV315-3EN40A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e40A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e500V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (Breaking Capacity):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e20kA @ 500V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBolt-on (3EN Terminal Type)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-arcing I²t:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e255 A²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Clearing I²t:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1020 A²s (@ 500V DC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Dissipation (Loss):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e8.0W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e-40°C to +125°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Compliance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eISO 8820, JASO D622, GB\/T 31465, RoHS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Application:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEV\/HEV Main\/Auxiliary Power Systems, Battery Packs, On-Board Chargers (OBC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePack of 10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sinofuse","offers":[{"title":"Default Title","offer_id":51771729477911,"sku":null,"price":77.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/9210\/1655\/files\/sinofuse-general-industrial-fuses-sinofuse-ev315-3en10a-electric-vehicle-fuse-10a-500v-dc-high-speed-bolt-on-pack-of-10-1214153525.png?v=1767506051","url":"https:\/\/www.apexonsupply.com\/products\/sinofuse-ev315-3en40a-electric-vehicle-fuse-40a-500v-dc-high-speed-bolt-on-pack-of-10","provider":"Apexon Solutions LLC","version":"1.0","type":"link"}
