Relaybox NGJRM552, 3-phase continuous, for controlling two single-phased light groups in an energy-saving solution. When daylight is enough one light group can be switched off by a twilight switch control. The other light group is controlled via a switch. In the EnstoNet installation system there are special prefabricated leads for connecting the switch to the switchbox (cable type: stranded HF cable). 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.
