{"id":991,"count":18,"description":"<p>A busbar is a piece of brass or copper to which several cables are connected to a single battery terminal. It replaces the stacking of terminals on the terminal block, which is one of the points where the most faults occur in direct current installations.<\/p>\n<h2>What is a distribution bar used for?<\/h2>\n<p>In a 12- or 24-volt system powered by the same battery, there are easily five or six power consumers: the inverter, solar regulator, charger, booster, power distribution unit and the battery monitor. Connecting six terminals to a single terminal block leads to loose connections, overheating and a fault that is difficult to pinpoint.<br \/>\nThe busbar distributes these connections to individual screw terminals with a cross-sectional area far greater than that of the cable, so that each load has its own connection point, tightened to the correct torque and easily accessible.<\/p>\n<h2>How do you choose the right busbar?<\/h2>\n<p><strong>Rated current.<\/strong> It must be capable of handling the sum of the currents that will flow through it in the worst-case scenario. Common models are rated at 150, 250, 400 and 600 A.<br \/>\n<strong>Number and size of screws.<\/strong> The <strong>M8 and M10 busbars<\/strong> These are the most commonly used in photovoltaic installations; the size must match that of your cable terminals.<br \/>\n<strong>Insulating cover.<\/strong> Essential: an exposed busbar near a battery is a short circuit just waiting for a spanner to fall on it.<\/p>\n<h2>12V busbar and Lynx systems<\/h2>\n<p>In small installations, one positive bar and one negative bar are sufficient. In larger systems, Lynx-type solutions from <a href=\"\/en\/brand\/victron\/\">Victron<\/a> They integrate the distribution board, the fuse holders for each circuit and the battery monitor into a single module, which reduces the amount of wiring required and makes the whole assembly much neater and easier to maintain.<\/p>\n<h2>What goes with it<\/h2>\n<p>Each branch leading off the busbar requires its own <a href=\"\/en\/product-category\/electrical-equipment\/fuses\/\">fuse<\/a> the correct size for the cable it protects, properly crimped terminals of the correct size, and cable of the appropriate cross-section \u2014 check this in the <a href=\"\/en\/how-to-calculate-the-cross-section-of-a-cable\/\">Cross-section table by power rating<\/a>.<br \/>\nTell us how many loads you\u2019re going to hang up and what maximum current you expect, and we\u2019ll tell you which rail you need: <a href=\"\/en\/victron-support\/\">free advice<\/a>.<\/p>","link":"https:\/\/fvcomponentes.com\/en\/categoria-producto\/material-electrico\/busbar\/","name":"Busbar","slug":"busbar","taxonomy":"product_cat","parent":410,"meta":[],"menu_order":88,"_links":{"self":[{"href":"https:\/\/fvcomponentes.com\/en\/wp-json\/wp\/v2\/product_cat\/991","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/fvcomponentes.com\/en\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/fvcomponentes.com\/en\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/fvcomponentes.com\/en\/wp-json\/wp\/v2\/product_cat\/410"}],"wp:post_type":[{"href":"https:\/\/fvcomponentes.com\/en\/wp-json\/wp\/v2\/product?product_cat=991"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
