Specifiers & BS EN 61439-2

BS EN 61439 Series Standards are now well established.

61439 Low Voltage Switchgear and Controlgear Assemblies, Parts 1 and 2 have a direct relationship with Power switchgear and control gear Assemblies for the panel building industry, in addition, Part 0 may be of particular interest to those compiling technical specifications.

The series is compiled as follows:

Part 0: Guidance to specifying assemblies.
Part 1: General Rules (generic types of assembly).
Part 2: Power switchgear & control gear assemblies.
Part 3: Distribution boards.
Part 4: Assemblies for construction sites.
Part 5: Assemblies for power distribution in public networks.
Part 6: Busbar trunking systems.

In accordance to the Standard, it is a requirement that all Assemblies are Verified (Design and Routine Verification) and supplied with information relating to these verified characteristics (e.g. operational voltage, IP code etc.)


Since the introduction of Part 2 in 2009, Elsteel have successfully completed a huge amount of Design Verifications by Test and continue to do so. The result is a vast library of Tested Reference Designs.

Companies wishing to supply 61439 compliant panels have the option of testing their own designs or, as is increasingly the case, to use a pre-tested modular assembly. 
This pre-tested modular assembly approach is embodied in Elsteel’s Design Verified –
Techno Module System. View all Certifications here.

Space Planning for Switch Rooms.
2Space Planning for Electrical Power Distribution and Control projects can be undertaken by Elsteel UK and TM Builder Network Partners during the early design stages to allow for adequate switch room sizing. We do this by engaging with End Users, Engineering Teams, Consulting Engineers and Specifiers to discuss switchboard or MCC requirements, taking an Electrical Schematic and producing detailed CAD General Arrangement drawings showing accurate panel sizing.
Project Teams can then move forward with more detailed design, confident that switchgear space requirements can be met.
