For medium-power circuits above 15A, this 0.8mm thickened terminal model is recommended for higher current carrying capacity and lower temperature rise. Choose a 6x30mm fuse with appropriate current rating based on actual load, and reserve a 1.25\u20131.5 times safety margin to prevent overheating during continuous operation. For equipment requiring front-panel fuse replacement, panel mount models are the preferred choice as they allow quick fuse replacement without opening the equipment enclosure. For flame retardant and insulation-sensitive scenarios, prioritize products with UL94 V0 grade housing and high insulation resistance to ensure operational safety.<\/p>\n<h2>Mga Karaniwang Senaryo ng Aplikasyon<\/h2>\n<ul>\n<li>Industrial control panels and medium-power automation equipment circuits<\/li>\n<li>Switching power supplies, industrial power modules and power distribution units<\/li>\n<li>Mga instrumento sa pagsubok at mga circuit ng suplay ng kuryente sa laboratoryo<\/li>\n<li>Household appliances and medium-power electrical equipment<\/li>\n<li>Communication equipment and network power supply systems<\/li>\n<li>Mga driver ng ilaw na LED at mga module ng kuryente na mababa ang boltahe<\/li>\n<li>Medical equipment auxiliary circuits and control systems<\/li>\n<\/ul>\n<h2>Mga Tagubilin sa Pag-install at Pagpapanatili<\/h2>\n<p>1. Select a 6x30mm cartridge fuse with correct current and voltage rating according to circuit protection requirements.<\/p>\n<p>2. Magbutas ng karaniwang butas para sa pagkakabit sa panel ng kagamitan, ipasok ang fuse holder mula sa harap, at higpitan ang fixing nut mula sa likod upang matiyak na matibay ang pagkakabit.<\/p>\n<p>3. Ikabit nang mahigpit ang mga kable ng circuit sa mga terminal sa likuran at lagyan ng wastong insulation treatment upang maiwasan ang mga panganib ng short circuit.<\/p>\n<p>4. Ipasok nang buo ang piyus sa lalagyan at higpitan ang takip sa dulo upang matiyak ang maaasahang pagganap ng contact at insulation.<\/p>\n<p>5. Huwag gumamit ng higit sa itinakdang boltahe at kasalukuyang saklaw upang maiwasan ang pagkasira ng insulasyon at mga panganib sa kaligtasan.<\/p>\n<p>6. Tanggalin nang tuluyan ang suplay ng kuryente bago palitan ang fuse upang maiwasan ang electric shock at short circuit damage.<\/p>\n<p>7. Pana-panahong siyasatin ang mga terminal at piyus para sa mga senyales ng pagkaluwag, oksihenasyon, o sobrang pag-init, at palitan agad ang mga bahagi kung may matagpuang abnormalidad.<\/p>\n<p><a href=\"https:\/\/essfuse.com\/wp-content\/uploads\/2025\/10\/R3-55A-Panel-fuse-holder.pdf\">R3-55A-Panel-fuse-holder<\/a><\/p>\n<h2>Mga Madalas Itanong<\/h2>\n<p><strong>Q1: What fuse size does this panel fuse holder support?<\/strong><\/p>\n<p>A1: It is compatible with all standard 6\u00d730mm glass and ceramic cartridge fuses, which is a widely used specification for low-voltage medium-power circuit protection.<\/p>\n<p><strong>T2: Ano ang rated current at voltage?<\/strong><\/p>\n<p>A2: The rated current is 20A, and the rated voltage supports 250V and 125V for both AC and DC, covering most medium-power electrical equipment protection scenarios.<\/p>\n<p><strong>T3: Anong materyal ang gawa sa pabahay?<\/strong><\/p>\n<p>A3: The housing is made of PBT engineering plastic with UL94 V0 flame retardant grade, featuring excellent insulation performance, high temperature resistance and flame retardant capability.<\/p>\n<p><strong>T4: Ano ang boltahe ng resistensya at resistensya sa pagkakabukod?<\/strong><\/p>\n<p>A4: Sinusuportahan nito ang boltaheng hindi tinatablan ng frequency ng kuryente na 3000V AC, na may insulation resistance na higit sa 100M\u03a9, na nagbibigay ng mataas na lakas ng insulasyon at kaligtasan sa pagpapatakbo para sa mga low-voltage circuit.<\/p>\n<p><strong>Q5: What material and thickness are the terminals?<\/strong><\/p>\n<p>A5: The terminals are made of 0.8mm thick phosphor bronze, with reinforced structure, high elasticity, contact resistance below 5m\u03a9, and stable clamping force for long-term use.<\/p>\n<p><strong>T6: Anong paraan ng pagkakabit ang ginagamit nito?<\/strong><\/p>\n<p>A6: Gumagamit ito ng disenyo ng panel mount na may istrukturang pangkabit na may sinulid na nut, na maaaring direktang mai-install sa mga front panel ng kagamitan at mga ibabaw ng control cabinet, na may matibay na pag-install at maginhawang pang-araw-araw na pagpapanatili.<\/p>\n<p><strong>T7: Ano ang mga pangunahing larangan ng aplikasyon?<\/strong><\/p>\n<p>A7: Widely used in industrial control equipment, switching power supplies, test instruments, household appliances, communication equipment and various medium-power low-voltage AC\/DC circuit overcurrent protection.<\/p>","protected":false},"excerpt":{"rendered":"<p>Industrial grade 6x30mm panel fuse holder with PBT UL94 V0 flame retardant housing and 0.8mm thick phosphor bronze terminals, 20A 250V\/125V AC\/DC rated, 3000V withstand voltage, designed for industrial power supplies, control equipment and distribution circuit overcurrent protection.<\/p>","protected":false},"featured_media":4024,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[155],"product_tag":[],"class_list":["post-4255","product","type-product","status-publish","has-post-thumbnail","product_cat-panel-fuse-holder","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/product\/4255","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/comments?post=4255"}],"version-history":[{"count":2,"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/product\/4255\/revisions"}],"predecessor-version":[{"id":15267,"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/product\/4255\/revisions\/15267"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/media\/4024"}],"wp:attachment":[{"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/media?parent=4255"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/product_brand?post=4255"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/product_cat?post=4255"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/essfuse.com\/tl\/wp-json\/wp\/v2\/product_tag?post=4255"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
