BS EN 61439-5:2015

What is BS EN 61439-5 - Assemblies for power distribution in public networks about?

BS EN 61439-5 is the fifth part of an international multi-series standard that deals with the aspects of low-voltage switchgear and control gear assemblies.

BS EN 61439-5 defines the specific requirements for public electricity network distribution assemblies (PENDAs).

Public electricity network distribution assemblies (PENDAs), have the following criteria:

• Used for the distribution of electrical energy in three-phase systems for which the rated voltage does not exceed 1000 V AC
• Stationary
• Suitable for installation in places where only skilled persons have access for their use, however, outdoor types may be installed in situations that are accessible to ordinary persons
• For indoor or outdoor use

The object of BS EN 61439-5 is to state the definitions and to specify the service conditions, construction requirements, technical characteristics, and tests for PENDAs. Network parameters may require tests at higher performance levels. PENDAs may also include control and or signalling devices associated with the distribution of electrical energy.

BS EN 61439-5 applies to all PENDAs whether they are designed, manufactured on a one-off basis, or fully standardized and manufactured in quantity. The manufacture and/or assembly may be carried out other than by the original manufacturer.

Note 1: BS EN 61439-5 does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, etc. which comply with the relevant product standards.

Note 2: BS EN 61439-5 does not apply to specific types of ASSEMBLIES covered by other parts of IEC 61439 series.

Note 3: Open ASSEMBLIES are not covered by BS EN 61439-5.

Who is BS EN 61439-5 - Assemblies for power distribution in public networks for?

BS EN 61439-5 on Assemblies for power distribution in public networks is useful for:

• Manufacturers and suppliers of low-voltage switchgear and control gear assemblies
• Safety certification providers for low-voltage switchgear and control gear assemblies
• Dealers and distributors of low-voltage switchgear and control gear assemblies
• Designers of low-voltage switchgear and control gear assemblies
• Regulatory authorities for low-voltage switchgear and control gear assemblies

Why should you use BS EN 61439-5 - Assemblies for power distribution in public networks?

Public electricity network distribution assemblies (PENDAs) are assemblies, that are generally utilized for installation in a public electricity network, which receives electrical energy from one or more supplies and distributes that energy through one or more cables to other equipment. PENDA is installed, operated, and maintained by solely skilled persons.  

BS EN 61439-5 gives you technical specifications of the low-voltage switchgear and control gear assemblies, in order to enable the users to follow the standardized guidelines for assemblies that are used for power distribution in public networks. It discusses the PENDAs i.e., public electricity network distribution assemblies which require consideration of specific criteria while designing and constructing such assemblies.

BS EN 61439-5 recommends the specifications such as interface characteristics, service conditions, constructional requirements, performance requirements, design verification, routine requirements which helps the users in verifying of performance of the assemblies for ensuring the high-quality, durability, reliability, and efficiency of assemblies for power distribution in public networks.
