Description of BS EN 61439-1:2009 2013

NOTE 1 Throughout this standard, the term ASSEMBLY (see 3.1.1) is used for a low-voltage switchgear and controlgear assembly.

This part of IEC 61439 lays down the definitions and states the service conditions, construction requirements, technical characteristics and verification requirements for low-voltage switchgear and controlgear assemblies.

This standard applies to low-voltage switchgear and controlgear assemblies (ASSEMBLIES) only when required by the relevant ASSEMBLY standard as follows:

  • ASSEMBLIES for which the rated voltage does not exceed 1 000 V in case of a.c. or 1 500 V in case of d.c.;

  • stationary or movable ASSEMBLIES with or without enclosure;

  • ASSEMBLIES intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electric energy consuming equipment;

  • ASSEMBLIES designed for use under special service conditions, for example in ships, in rail vehicles, for equipment in explosive atmospheres, and for domestic applications (operated by unskilled persons), provided that the relevant specific requirements are complied with;

    NOTE 2 Supplementary requirements for ASSEMBLIES in ships are covered by IEC 60092-302.

    NOTE 3 Supplementary requirements for ASSEMBLIES in explosive atmospheres are covered by the IEC 60079 series and the IEC 61241 series.

  • ASSEMBLIES designed for electrical equipment of machines. Supplementary requirements for ASSEMBLIES forming part of a machine are covered by the IEC 60204 series.

This standard applies to all ASSEMBLIES whether they are designed, manufactured and verified on a one-off basis or fully standardised and manufactured in quantity.

The manufacture and/or assembly may be carried out other than by the original manufacturer (see 3.10.1).

This standard cannot be used alone to specify an ASSEMBLY or used for a purpose of determining conformity.

This standard does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, etc. which will comply with the relevant product standards.
