Preferably, the back plate of said drawer is a plate behind the metal drawer.

Pass through technique scheme; The MNS type low-tension switch cabinet that the utility model provides; With reference to the GCK prior art,, replace the right angle busbar with the vertical busbar of a word with the cancellation of plastic functional plate; Use plug-in unit substituting disposable contact in the drawer; The digital and analog hole that its KB section bar adopts can be squeezed into from single face with the self-tapping screw of high strength M6 and assemble, and it has following advantage:

1. owing to cancelled the use of plastic functional plate, a whole set of cabinet cost is intrinsic 60-80%;

2. the vertical busbar of a word replaces the right angle busbar, and the rated current of vertical bus can be changed to 1800A by 400A, and rated current is low can the material saving, and the rated current height can maximum satisfy client's demand;

3. complete sets of products can use plain conductor assembling drawer; Intercepting lead on demand; And the digital and analog hole that the KB section bar adopts

; Can squeeze into from single face with high strength M6 self-tapping screw, assembling is not only convenient but also save.
