Overview
This part of the DIN EN 61439 (VDE 0660-600) series of standards gives specific requirements for public electricity network distribution assemblies, short designation "PENDAs", which are stationary assemblies as defined in this standard. These assemblies are used for the distribution of electrical energy in three-phase systems. Only assemblies with enclosure are considered; open type assemblies are not covered by this standard. The object of this standard 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. This standard applies to all PENDAs whether they are designed, manufactured on a one-off basis or fully standardised and manufactured in quantity. The significant modifications concern: - 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. The responsible committee is Subcommittee DKE/UK 431.1 "Niederspannungs-Schaltgerätekombinationen" ("Low-voltage switchgear and controlgear assemblies") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
