Switchgear cabinets with a modular rack design
GREINER GNS distribution boards
GREINER GNS system l.v. distribution board
The GREINER GNS distribution board represents switchgear designed using modular board technology.
It is highly suitable both for motor and lighting feeders.
A back-up fuse is fitted for each outgoing board.This allows replacements or expansions to be carried out at any time.
The GREINER GNS distribution board can therefore be regarded as a low-cost alternative to the withdrawable technology system.
The GREINER GNS system is a type-tested switchgear assembly in accordance with DIN EN 60439-1.

Due to the modular rack design, the switchgear cabinet essentially consists of the supporting rack frame and the cladding panels.The supporting rack frame is constructed from 50 mm wide C-section rails.The C-rails are manufactured from galvanised sheet steel, 2 mm thick, with holes at regular 25 mm intervals(DIN 43 660).
The modular principle, using a basic grid in accordance with DIN 43 660, is rigorously adhered to as regards both the mechanical and electrical designs.Cubicle dimensions are based on grid increments of 200 mm in accordance with DIN 41 488.
This allows individual demands for flexibility in design and efficient installation to be met.
The switchgear cubicles all have a standardised basic structure, consisting of the following function compartments:
The device and cable terminal compartments can be partitioned off from adjacent compartments, i.e. also making separate access facilities with single doors possible.
These doors can be supplied with or without a window and can be customised in terms of size.
All doors are fitted with an espagnolette lock and tumbler arrangement.
All cubicles are designed so that they can always be added to.
