When seeing applications for low-voltage surge arresters that allow installation up to 4,000A, especially in Class B, a questioning technical person naturally wonders\u2014and they do: how is it possible to connect a surge arrester to a 4,000A MCCB (Molded Case Circuit Breaker)?<\/p>\n
Then suddenly, you see a fuse being recommended in between, and a technician on a forum asks: “Why are we protecting the surge arrester with a fuse?”<\/p>\n
Of course, the same handful of people immediately step in with panic and explain confidently: “We are not protecting the surge arrester; it is protecting us.” The man continues to ask, “Well then, why do we put a fuse in front of the surge arrester?”<\/p>\n
Immediate explanations follow: “Because at high currents, the surge arrester must trip the fuse and prevent energy from reaching the system.”<\/p>\n
But wouldn’t you only be protecting the surge arrester itself by placing a fuse in front of a parallel-connected protection product? In other words, if the fuse you installed trips, won’t the systems fed by that 4,000A line continue to suffer damage?<\/p>\n
The man gives up and stops asking. Because that handful of surge arrester importers or salespeople on the forum eventually wear him down.<\/p>\n
Surge arrester importers recommend a 125A fuse for Class B and a 63A fuse for Class C if they are to be used for larger systems in surge arrester applications. Technicians who know how a surge arrester functions also know that a surge arrester has no chance of tripping a 125A fuse during a phase-to-ground short circuit.<\/p>\n
To trip a 125A fuse during a phase-to-ground short circuit, a residual current device (RCD) could be used, but that cannot be used either because it doesn’t hold and constantly trips in surge arrester applications.<\/p>\n
In systems where surge arresters are required, by using Trimbox new generation surge arresters, you eliminate the obligation to place an additional fuse in between, provide protection for all classes with a single product, and additionally perform overvoltage protection.<\/p>\n
Simple precautions sometimes save lives. The best investment<\/strong> we can make for our family, our business, and our environment is protective measures<\/strong>. With Trimbox and GNDSeries<\/strong>, you can be protected from electricity-related damages and electrical contact fires caused by them.<\/p>\n Whatsapp : +90 555 014 24 23<\/strong><\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" When seeing applications for low-voltage surge arresters that allow installation up to 4,000A, especially in Class B, a questioning technical person naturally wonders\u2014and they do: how is it possible to connect a surge arrester to a 4,000A MCCB (Molded [\u2026]<\/span><\/p>\n","protected":false},"author":1,"featured_media":1834,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[30],"tags":[],"class_list":["post-3210","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog-en"],"_links":{"self":[{"href":"https:\/\/trimbox.com.tr\/en\/wp-json\/wp\/v2\/posts\/3210","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/trimbox.com.tr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/trimbox.com.tr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/trimbox.com.tr\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/trimbox.com.tr\/en\/wp-json\/wp\/v2\/comments?post=3210"}],"version-history":[{"count":0,"href":"https:\/\/trimbox.com.tr\/en\/wp-json\/wp\/v2\/posts\/3210\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/trimbox.com.tr\/en\/wp-json\/wp\/v2\/media\/1834"}],"wp:attachment":[{"href":"https:\/\/trimbox.com.tr\/en\/wp-json\/wp\/v2\/media?parent=3210"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/trimbox.com.tr\/en\/wp-json\/wp\/v2\/categories?post=3210"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/trimbox.com.tr\/en\/wp-json\/wp\/v2\/tags?post=3210"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
