POWER AND DISTRIBUTION CATALOGUE 2008 - ELDON - #3

ELDON POWER SYSTEM

Eldon's new modular low voltage system is based on the existing Multi-Flex mild steel floor standing enclosure, and therefore allows the user to design and build a complete solution from essentially a standard range of enclosures and accessories.

There is no limit to the size of project this system can handle (small, medium and large assemblies), and it can be used for a variety of different applications:

• Control aplications.

• Electrical distribution panels.

• Power systems.

To further enhance the flexibility of the system, the designer or end user can specify any brand of electrical components to be used, as there are no restrictions to make, type or size.

The frame is a fully welded construction which helps guarantee the highest rigidity, and the possibility of coping with the very highest Icc (short-circuit current) requirements.

With the Eldon Power System different levels of segregation can be made according to EN 60439-1

Form 1, There are not any internal separation.

^^^^^^ Form 2, Separation of busbars from the functional units.

Form 2a: Terminals for external conductors not separated from busbars Form 2b: Terminals for external conductors separated from busbars

Form 3, The Form 2 separations, additional separation of all functional units from one another and separation of terminals for external conductors from the functional units.

Form 3a: Terminals for external conductors not separated from busbars

Form 3b: Terminals for external conductors separated from busbars

TT

Form 4, The Form 2 separations, additional separation of terminals for external conductors from those of any other functional unit and the busbar.

Form 4a: Terminals for external conductors in the same compartment as the associated functional unit Form 4b: Terminals for external conductors not in the same compartment as the associated functional unit, but in individual spaces or compartments

The Eldon Power System has been tested by ETL-Semko and ASTA according to IEC/EN 60439-1. The TTA tests were performed on fully equipped assemblies containing different IP ratings and various forms of internal segregation, and other system features such as a combination of different busbar systems.

One of the main advantages of the Eldon system is that you are able to manufacture a fully type-tested low-voltage switchgear and con-trolgear assembly (TTA) according to EN 64039-1. However, every system should meet the following conditions:

• The switching devices and components incorporated in the assembly shall comply with the relevant IEC standards, and should be suitable for the particular application with respect to the external design, rated voltages, rated currents, rated frequency, short-circuit protection, etc.

• The electrical connections inside the assembly must comply with EN 60439-1 7.8.

By following these standards and the relevant mounting instructions, the user only has to carry out the usual routine testing once the system is fully assembled, instead of any additional type testing (Wiring and electrical operation, dielectric properties and protective measures accord­ing to EN 60439-1 8).
