switch safely handle the highest DC voltage in your system? Current rating \u2014 can it carry the expected continuous current without overheating? Pole configuration \u2014 how many conductors does it disconnect at the same time? Utilization category \u2014 what kind of DC switching duty was it actually tested for? An engineer carefully inspecting the ratings on a DC isolator switch at a solar PV installation to ensure system safety and compliance. The order matters. In practice, the most frequent rating mistakes happen when buyers focus on the [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":23389,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[1],"tags":[],"class_list":["post-23388","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/posts\/23388","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/comments?post=23388"}],"version-history":[{"count":1,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/posts\/23388\/revisions"}],"predecessor-version":[{"id":23390,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/posts\/23388\/revisions\/23390"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/media\/23389"}],"wp:attachment":[{"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/media?parent=23388"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/categories?post=23388"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/test.viox.com\/ja\/wp-json\/wp\/v2\/tags?post=23388"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
