For dusty, humid or industrial environments, models with dustproof cover are strongly recommended to avoid contact oxidation and poor contact caused by dust accumulation. Always match the fuse rating with the actual working current of the circuit, reserving a 1.25-1.5 times safety margin to avoid premature fuse failure or insufficient protection. For high-temperature operating environments above 60\u2103, derate the current appropriately to ensure long-term reliable operation.<\/p>\n<h2>Scenari applicativi<\/h2>\n<ul>\n<li>Alimentatori switching, adattatori CA\/CC e circuiti di ricarica<\/li>\n<li>Schede di controllo per elettrodomestici e piccoli apparecchi elettrici<\/li>\n<li>Strumentazione per il controllo industriale e apparecchiature di automazione<\/li>\n<li>Apparecchiature di comunicazione e dispositivi terminali di rete<\/li>\n<li>circuiti di pilotaggio per illuminazione a LED<\/li>\n<li>Industrial control boards and electronic circuit protection<\/li>\n<li>Power distribution modules for dusty workshop equipment<\/li>\n<\/ul>\n<h2>Note di installazione e utilizzo<\/h2>\n<p>1. Select a matching 5x20mm glass tube fuse with appropriate current rating according to circuit protection requirements.<\/p>\n<p>2. Assicurarsi di eseguire saldature di qualit\u00e0 adeguata durante l&#039;installazione a foro passante per evitare giunzioni di saldatura fredde che causano un aumento della resistenza di contatto e il surriscaldamento.<\/p>\n<p>3. Close the dustproof cover after installing the fuse to achieve the expected dust and debris protection effect.<\/p>\n<p>4. Do not use the fuse holder beyond its rated voltage and current range to prevent insulation breakdown and safety hazards.<\/p>\n<p>5. Disconnect the power supply before replacing the fuse to avoid electric shock and short-circuit damage.<\/p>\n<p>6. Store in a dry, dust-free and corrosion-free environment to prevent terminal oxidation and insulation performance degradation.<\/p>\n<pre><code>Its dustproof enclosure also makes it a reliable choice for outdoor equipment and industrial workshop devices with relatively high dust levels\r\n<\/code><\/pre>","protected":false},"excerpt":{"rendered":"<p>5x20mm PCB mount fuse holder with dustproof cover, PBT UL94 V0 flame retardant housing with nickel plated brass terminals, 6.3A\/10A 250V AC, through hole soldering for electronic circuit overcurrent protection, RoHS CE certified.<\/p>","protected":false},"featured_media":12967,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[148],"product_tag":[],"class_list":["post-12965","product","type-product","status-publish","has-post-thumbnail","product_cat-pcb-fuse-holder-clip","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/product\/12965","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/comments?post=12965"}],"version-history":[{"count":2,"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/product\/12965\/revisions"}],"predecessor-version":[{"id":15221,"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/product\/12965\/revisions\/15221"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/media\/12967"}],"wp:attachment":[{"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/media?parent=12965"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/product_brand?post=12965"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/product_cat?post=12965"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/essfuse.com\/it\/wp-json\/wp\/v2\/product_tag?post=12965"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
