3P Busbars and Distribution Blocks

3P Busbars and Distribution Blocks prices and range: 21 models with current prices, stock status and specifications at Welibaba. A distribution busbar and distribution block is a connection element that shares a single supply across several outputs in a panel or collects conductors at the same potential at one point. It is used to feed side-by-side MCBs with a single part, distribute phases and neutral from the main switch to the feeders, and collect neutral and protective conductors on separate busbars. In this category, Onka covered distribution units (distribution busbars) are offered in types such as 2-, 3- and 4-pole and 12-, 15- and 22-hole, at currents such as 80 A, 160 A and 250 A. Gwest and Konsan single-phase and three-phase common W-type MCB busbars, Konsan screw-type neutral and grounding busbars, Gwest rail-mounted distribution blocks and Schneider Electric Acti 9 comb busbars are also available. Choose the rated current by the current of the switch feeding the busbar, the pole count by the number of phases and neutrals to be distributed, the hole count by the number of feeders and the hole size by the conductor cross-section; for an MCB busbar, determine the phase type and length by the MCB row. A comb-type MCB busbar only bridges MCBs on the same rail and does not replace the panel's main busbar.
