The switchbox NGJKMF341 is intended for two change over switch connections e.g. in corridors. The single-phase incoming and outgoing is branched into two 3-pole outgoings for change over switches and two supplies for light fittings. The distribution box can be fixed e.g. to the installation plate by screws, max. ø 6 mm, two holes in the middle (distance between holes 75 mm) or 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.
