We utilize high-quality high carbon steel and low carbon cold rolled steel to ensure the utmost durability and performance of our products. The main iron parts are crafted from iron base materials, specifically cold rolled steel 10 steel, known for its exceptional strength and resilience. By employing A+ materials throughout our manufacturing process, we guarantee the reliability and longevity of our products.<\/p>\n<p>Furthermore, our dedication to enhancing the properties of our materials is exemplified through the implementation of QPQ salt bath composite treatment. This advanced treatment significantly improves the wear resistance, corrosion resistance, and fatigue resistance of the metal surface, ensuring that our products can withstand the harshest operating conditions. As a result, the strength, mechanical life, and electrical life of our parts are enhanced by more than 10%, providing our customers with superior performance and peace of mind.<\/p>\n<p>In summary, our unwavering commitment to utilizing top-quality materials and employing advanced treatments underscores our dedication to delivering products that exceed industry standards and meet the diverse needs of our customers.<\/p>\n<p>The operational profile of renewable sources also demands unique performance characteristics. Solar and wind power generation is inherently intermittent, leading to frequent load cycling. MCCBs in these applications must be rated for a high number of mechanical and electrical operations without degradation. Additionally, they are designed to handle potential fault currents from both the generator side (e.g., a short circuit in a PV string) and the utility grid side. Advanced models offer adjustable trip settings, allowing engineers to finely tune protection coordination between breakers, inverters, and other system components to prevent nuisance tripping and ensure selective coordination, isolating only the faulty section.<\/p>","protected":false},"excerpt":{"rendered":"<p>\uc815\uaca9 \uc804\ub958 : 400A \ud3f4\ub780\ub4dc \uc218 : 3P \uc815\uaca9 \uc791\ub3d9 \uc804\uc555 : 380V\/690V<\/p>","protected":false},"featured_media":2912,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[185],"product_tag":[],"class_list":["post-2911","product","type-product","status-publish","has-post-thumbnail","product_cat-thermal-mccb-industrial-products","first","instock","shipping-taxable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/w9-group.com\/ko\/wp-json\/wp\/v2\/product\/2911","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/w9-group.com\/ko\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/w9-group.com\/ko\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/w9-group.com\/ko\/wp-json\/wp\/v2\/comments?post=2911"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/w9-group.com\/ko\/wp-json\/wp\/v2\/media\/2912"}],"wp:attachment":[{"href":"https:\/\/w9-group.com\/ko\/wp-json\/wp\/v2\/media?parent=2911"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/w9-group.com\/ko\/wp-json\/wp\/v2\/product_brand?post=2911"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/w9-group.com\/ko\/wp-json\/wp\/v2\/product_cat?post=2911"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/w9-group.com\/ko\/wp-json\/wp\/v2\/product_tag?post=2911"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
