• Hello everyone,
  
  I have just noticed that there is an assembly installed before each power supply unit, I would like to know why ? what is the point of this assembly ? and why the one framed in red has a breaker and the other does not, what is the difference between them ?
  
  Thank you so much !!

• The purpose of the "no fuse breaker", and "NF", are to isolate the unit from the supply so that it can be safely worked on.
