Post-arcing time is the time required to completely extinguish the electric arc after melting, directly affecting the breaking safety of high-current circuits.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The total I\u00b2t value is the sum of pre-arc I\u00b2t and post-arc I\u00b2t, which is the key basis for matching power electronic components such as IGBT. Different current multiples correspond to different standard breaking times.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to IEC, GB and UL standards, aR <a href=\"https:\/\/essfuse.com\/ko\/product-category\/north-american-semiconductor-fuse\/\">semiconductor fuses<\/a> focus on short-circuit rapid breaking, with strict requirements on arc extinguishing performance and I\u00b2t characteristic stability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">EssFuse full series <a href=\"https:\/\/essfuse.com\/ko\/product-category\/square-high-speed-fuse\/\">high speed fuses<\/a> have stable pre-arc and post-arc parameters, complete test data, and meet global mainstream certification standards.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Pre-arcing time and post-arcing time are core performance parameters of high-speed fuses, widely used in semiconductor protection, new energy vehicles<\/p>","protected":false},"author":16,"featured_media":15423,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[158],"tags":[],"class_list":["post-13906","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-essfuse-news-fuse-industry-insights"],"_links":{"self":[{"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/posts\/13906","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/users\/16"}],"replies":[{"embeddable":true,"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/comments?post=13906"}],"version-history":[{"count":1,"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/posts\/13906\/revisions"}],"predecessor-version":[{"id":13908,"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/posts\/13906\/revisions\/13908"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/media\/15423"}],"wp:attachment":[{"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/media?parent=13906"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/categories?post=13906"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/essfuse.com\/ko\/wp-json\/wp\/v2\/tags?post=13906"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
