• Typ D 103 open type for non-accessible compact substations • Typ 81, open type for non-accessible compact substations • Typ 84, sheet steel-enclosed type, space-saving • Typ 86, sheet steel-enclosed type for accessible substations The following standard design consisting of standard mounting systems is available: • closed version, type 84/86 • open-framework design, type 81 In accessible electrical operating areas low voltage systems in closed version (sheet steel-enclosed), type 84/86 ,are used (protection type: IP 2X). Distribution systems in framework design (type 81) are preferentially used...

• Type 81 (open design) for non-accessible compact sub-stations Measuring in input or output panels can be realized as well with analog and digital built-in measuring instruments The output panels are factory-designed in such a way that the outer outputs can be refitted (even later) with switches 630 A and this does not depend on the width of the panel. Instead of a 400 A / 630 A output two distributions systems of 160 A can also be mounted. On request back covers are also available. For a free standing version fixing angles can be mounted on option. Tecnical data: Rated voltage Ue Rated insulation...

• Type D 103 open design The low voltage system D 103 was designed within the M100 series as model especially for the application in accessible and non-accessible substations. The basic conception of the system is a modular design consisting of a self-supporting basic plate made of sheet steel. For the choice of material the latest state-of-the-art on leakage current according to Generic Standards (EN 50081) has been taken into consideration. For this the completely closed sheet steel rear panel offers best possibilities. Furthermore, due to the best possible design of a moulded holding plate...
