Socket outlet box NAP500, three-phase continuous with internal phase rotations is branched into two double socket outlets. The socket outlet box can be fixed e.g. to the installation plate by screws, max. ø 6 mm, four holes in the corners of the box. The boxes can also be fixed with two cable ties from the clamps on the box base. The third way of fixing is by using the so-called snap-on pins, for which there are four fixing holes on the box base.
