What is the IEC 61439?
IEC 61439 defines which points the manufacturer and the user of a switchgear and controlgear assembly have to define. The switchgear and controlgear assembly is viewed as a so-called black box, whose interfaces to the environment are defined in 4 areas.
What IEC 62208?
IEC 62208. August 1, 2011. Empty enclosures for low-voltage switchgear and controlgear assemblies – General requirements. This International Standard applies to empty enclosures, prior to the incorporation of switchgear and controlgear components by the user, as supplied by the enclosure manufacturer.
What is IEC type test?
Type tests defined in IEC 61439. Certification of distribution assemblies is defined by international standard IEC 61439-1. Compliance with the standard is certified, depending on the country or market, by a declaration of the panel builder, the design office, the installer or the user.
What is a TTA panel?
Type Tested Assemblies(TTAs) A low voltage switchgear and control gear assembly/control panel conforming to an established type or system without any deviations likely to significantly influence the performance, from the typical assembly verified to be in accordance with this standard.
What is the difference between 60439 and 61439?
IEC 61439-5 will replace IEC 60439-5 (still valid) The new IEC 61439 standard applies to enclosures for which the rated voltage is under 1000 V AC (at frequencies not exceeding 1000 Hz) or 1500 V DC. The standard defines the design verified ASSEMBLIES and eliminates completely the categories TTA and PTTA.
What is type tested?
Conformance testing — an element of conformity assessment, and also known as compliance testing, or type testing — is testing or other activities that determine whether a process, product, or service complies with the requirements of a specification, technical standard, contract, or regulation.
Who is an operator in DIN IEC 61439?
A person involved who will specify, purchase, use and/or operate the switchgear and controlgear assembly or someone who acts on the user’s behalf [DIN EN (IEC) 61439-1 (3.10.3]. e.g. engineer, operator. IEC 61439 defines which points the manufacturer and the user of a switchgear and controlgear assembly have to define.
Who is responsible for routine verification of norm IEC 61439?
This can also be identical with an original manufacturer [DIN EN (IEC) 61439-1 (3.10.2)]. The switchboard system or cubicle manufacturer bears the responsibility for routine verification.
What is the Black Box concept in IEC 61439?
IEC 61439 defines which points the manufacturer and the user of a switchgear and controlgear assembly have to define. The switchgear and controlgear assembly is viewed as a so-called black box, whose interfaces to the environment are defined in 4 areas. Here you will find further information about the black box concept
What was the purpose of the IEC 60439 standard?
The IEC 60439 standards were ambiguous about how to assess compliance of partially type tested assemblies. As a result manufacturers and testing bodies often treated partially type-tested assemblies differently.
