A new standard. A new opportunity. IEC 61439 is the new standard governing the production of switchgear and controlgear assemblies, and reinforces the holistic system concept of a low-voltage switchgear and controlgear assembly – an idea developed and successfully established over many years by Rittal. With its broad, modular range of products, Rittal – The System. covers virtually all plant categories, thereby offering a comprehensive approach to the construction of a switchgear and controlgear assembly and conformity with the new standard. Rittal products already come supplied with much...

The new standard EC 61439, as the successor to standard IEC 60439, outlines the requirements and verifications for all low-voltage switchgear and controlgear assemblies. The standard is applicable to power distri- butors, all switchgear and controlgear assemblies, meter boxes and Meter boxes Switchgear and controlgear Building distributors from wall-mounted enclosures ENCLOSURES » POWER DISTRIBUTION » CLIMATE CONTROL

What has changed under the new standard? The terms for type-tested switchgear and controlgear assemblies (TTA) and partially type-tested switchgear and controlgear assemblies (PTTA) used in IEC 60439-1 have been abolished. In future, only the system as a whole will be considered, and the term 'switchgear and controlgear assembly' will apply. For new switchgear and controlgear assemblies, the type test report will be replaced by the design verification. The former routine test report will be replaced by the routine verification. The user or planner describes a low-voltage switchgear and...

What does the new standard mean for you? IEC 61439 provides the basis for a clear definition of the performance promise made between the user and manufacturer of a switchgear or controlgear assembly. In this way, fulfilment of the performance promise can be assessed and documented for both parties. Application of the new standard does not entail significantly more work than testing a TTA/PTTA assembly. The calculation method for temperature increase in systems up to 1600 A remains unchanged. For systems up to 630 A the procedure has even been simplified. IEC 61439 guides the manufacturer...

Within the European trade zone, a declaration of CE conformity must be prepared for low-voltage switchgear and controlgear assemblies. The declaration makes reference to the Low-Voltage Directive, the EMC Directive and (where applicable) the Machinery Directive, as well as to product standard IEC 61439 and (where applicable) other standards such as IEC 60204 for the safety equipment of machines and plant. Any manufacturer wishing to produce and market standard-compliant switchgear or controlgear assembly after November 2014 must prepare a design verification and a routine verification. The...

Strength of materials Most of the required verifications for material strength already exist, due to compliance with the requirements of standard IEC 62208 on empty enclosures. This is sufficient for the purposes of verification to IEC 61439, provided no major alterations are made to the empty enclosure. However, documentation of the mechanical properties is required. The Rittal TS 8 load brochure contains all the required data for professional execution of the mechanical configuration.

Protection category of enclosures The protection category verification for enclosures ensures long-term protection of the valuable electrical equipment. Design verification within the framework of IEC 61439 requires separate testing. Rittal has its own laboratory division which is used, not only for one-off initial testing, but also for regular production monitoring.
