      When specifying terminal blocks for your electrical project, understanding terminal block pitch is essential to making the right selection. The pitch\u2014measured as the center-to-center distance between adjacent terminal poles\u2014directly impacts wire compatibility, current capacity, panel density, and safety compliance. Whether you’re designing compact PCB layouts or industrial power distribution systems, selecting the correct pitch ensures […]<\/p>\n","protected":false},"author":1,"featured_media":20711,"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-20709","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/posts\/20709","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/comments?post=20709"}],"version-history":[{"count":4,"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/posts\/20709\/revisions"}],"predecessor-version":[{"id":20714,"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/posts\/20709\/revisions\/20714"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/media\/20711"}],"wp:attachment":[{"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/media?parent=20709"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/categories?post=20709"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/test.viox.com\/cs\/wp-json\/wp\/v2\/tags?post=20709"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
