Specifically, we designed it for electric vehicle (EV\/HEV) battery pack protection, onboard chargers and DC relay backup protection. Moreover, it supports current ratings from 10A to 100A with a 50kA breaking capacity at 750Vdc. As a result, this compact bolt-on fuse is manufactured to meet strict IATF16949 automotive quality standards. In addition, it complies with JASO D622, UL 248.1\/248.13, IEC 60269 and GB 13539. For instance, it can open up to 10 times faster under heavy fault currents. Therefore, it maintains low watt loss and delivers outstanding vibration resistance for harsh automotive environments.<\/p>\n<h2>Key Features<\/h2>\n<ul>\n<li>Rated Voltage: 750Vdc<\/li>\n<li>Rated Current Range: 10A \u2013 100A (14 standard ratings)<\/li>\n<li>Breaking Capacity: 50kA at 750Vdc<\/li>\n<li>Fuse Type: Fast-Acting (high-speed)<\/li>\n<li>Automotive Grade: IATF16949 Quality System Certified<\/li>\n<li>EV\/HEV Designed \u2014 battery pack, onboard charger, DC relay backup<\/li>\n<li>Up to 10x Faster Opening under high fault currents<\/li>\n<li>Low Watt Loss \u2014 energy efficient design<\/li>\n<li>Parallel Application Capable \u2014 higher ampacity in compact size<\/li>\n<li>Excellent Vibration &amp; Impact Resistance<\/li>\n<li>Flush Bolt-On Mounting with M5\/M6 terminals<\/li>\n<li>Standards: UL 248.1\/248.13, IEC 60269.1\/.4, GB 13539.1\/.4, JASO D622, CE, RoHS<\/li>\n<\/ul>\n<h2>Typical Applications<\/h2>\n<p>Since this fuse is built to automotive-grade requirements, it can be deployed across many high-voltage DC protection scenarios.

Furthermore, it complies with JASO D622. Consequently, it delivers excellent vibration resistance and fast fault response. Therefore, engineers trust it for EV battery pack and onboard charger protection.<\/p>\n<h3>2: What is 750Vdc used for?<\/h3>\n<p>750Vdc is a common voltage level in EV\/HEV battery systems, onboard chargers (OBC) and fast charging stations. Specifically, this voltage class sits between 500V and 1000V EV platforms.<\/p>\n<h3>3: What standards does this fuse meet?<\/h3>\n<p>It meets multiple international standards. For example, it carries UL 248.1\/248.13 (US), IEC 60269.1\/.4 (international), GB 13539.1\/.4 (China), and JASO D622 (Japan). In addition, it is CE marked and RoHS compliant.<\/p>\n<h3>4: How many ampere ratings are available?<\/h3>\n<p>We offer 14 standard ratings from 10A to 100A: 10, 16, 20, 25, 32, 35, 40, 45, 50, 63, 70, 80, 90, and 100A.<\/p>\n<h3>5: Can fuses be used in parallel?<\/h3>\n<p>Yes. You can apply fuses in parallel to achieve greater ampacity within compact dimensions. However, please follow proper sizing guidelines before implementation.<\/p>\n<h3>6: What mounting type is used?<\/h3>\n<p>The fuse uses a flush bolt-on design with M5 or M6 terminals. Moreover, we recommend a torque of 4.5\u00b11.0 N\u00b7m (M5) or 6.0\u00b11.0 N\u00b7m (M6).<\/p>\n<h2>Downloads<\/h2>\n<ul>\n<li>Datasheet: <a href=\"https:\/\/gfevfuse.com\/wp-content\/uploads\/2026\/09\/GFEVT750-18R-10-100A-DC-Fast-acting-fuse.pdf\">GFEVT750-18R Datasheet (PDF)<\/a><\/li>\n<li>Time-Current Curves: included in datasheet<\/li>\n<li>IATF16949 Certificate: available upon request<\/li>\n<li>REACH Declaration: available upon request<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>GFEVT750-18R \u0938\u0940\u0930\u0940\u091c\u093c \u0915\u093e 750Vdc \u092b\u093e\u0938\u094d\u091f \u090f\u0915\u094d\u091f\u093f\u0902\u0917 \u092b\u094d\u092f\u0942\u091c\u093c, 10-100A, 50kA \u092c\u094d\u0930\u0947\u0915\u093f\u0902\u0917\u0964 EV\/HEV \u092c\u0948\u091f\u0930\u0940 \u092a\u0948\u0915, \u0911\u0928\u092c\u094b\u0930\u094d\u0921 \u091a\u093e\u0930\u094d\u091c\u0930 \u0914\u0930 DC \u0930\u093f\u0932\u0947 \u092c\u0948\u0915\u0905\u092a \u0915\u0947 \u0932\u093f\u090f IATF16949 \u0911\u091f\u094b\u092e\u094b\u091f\u093f\u0935-\u0917\u094d\u0930\u0947\u0921 DC \u092b\u094d\u092f\u0942\u091c\u093c\u0964 UL 248, IEC 60269 \u092a\u094d\u0930\u092e\u093e\u0923\u093f\u0924\u0964.<\/p>","protected":false},"featured_media":31149,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[80],"product_tag":[],"class_list":["post-31148","product","type-product","status-publish","has-post-thumbnail","product_cat-british-standard-fuses","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/product\/31148","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/comments?post=31148"}],"version-history":[{"count":8,"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/product\/31148\/revisions"}],"predecessor-version":[{"id":32570,"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/product\/31148\/revisions\/32570"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/media\/31149"}],"wp:attachment":[{"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/media?parent=31148"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/product_brand?post=31148"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/product_cat?post=31148"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/gfevfuse.com\/hi\/wp-json\/wp\/v2\/product_tag?post=31148"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
