DS/EN 61439-5:2015

IEC 61439-5:2014 defines the specific requirements for public electricity network distribution assemblies (PENDAs). PENDAs have the following criteria:

- used for the distribution of electrical energy in three phase systems for which the rated voltage does not exceed 1 000 V a.c. (see Figure 101 for a typical distribution network);

- open ASSEMBLIES are not covered by this standard;

- 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.

This second edition cancels and replaces the first edition published in 2010. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the latest edition:

- confirmation that tests carried out on the most onerous PENDA are deemed to verify the performance of similar and less onerous assemblies of the same general construction and rating;

- more precise timing/conditions for impact force withstand tests for PENDAs designed for operation in an arctic climate;

- correction of the direction of the applied force in the static load test.
