General product properties

RITTER Low voltage switchgear NS3001 is supplied in factory-assembled, type-tested design. The switchgear is assembled with galvanised sheet-steel, bolted and riveted. The doors and covers are painted in the RAL7035. The colour can be changed. RITTER low voltage switchgear assemblies of type NS3001 are tested for resistance to internal faults.

The main busbar is arranged on the back side, in the middle of the switchgear. The busbars are linked from panel to panel; this makes it possible for the system to be extended or to replace one panel in the system in a simple manner. All system can be located back-to-back, free standing or against a wall. Installation and dismantling work can be carried out from the front of the system.

Types of protection

The encapsulation of the NS 3001 switchgear assemblies is in accordance with IP31, but can also be executed in accordance with IP41. Higher protection types normally resulted with reductions in the rated value.

The insides compartmentalisation and low-voltage niche are produced in with protections type IP2X.
