TTA Panel / IEC 61439 Panel

IEC 61439 Panel / IEC 61439 Type Tested Panel / TTA Panel / Type Tested Assembly (TTA)

IEC 61439 Panel / IEC 61439 Type Tested Panel / TTA Panel / Type Tested Assembly (TTA)

Hi Tech Control Services are manufacturers & exporters of IEC 61439 Panel / IEC 61439 Type Tested Panel in India. A low-voltage switchgear and control gear assembly (ASSEMBLY) is a combination of low-voltage switching devices together with associated equipment (for controlling, measuring, signalling, etc.) complete with all the internal mechanical and electrical interconnections and structural parts. As with every component of an electrical installation, the ASSEMBLY also has to comply with its appropriate standard.

We manufacture a wide range of Electrical Panels. If you are looking to buy TTA Panel / IEC 61439 Panel, contact us today.

In January 2009 the IEC 61439, the new standard for lowvoltage switchgear and controlgear ASSEMBLIES, was published. This was the aim of an international project group which had been working on a task named "radical restructuring and revision of IEC 60439 series" since 1998. This initiative was introduced by several countries following dissatisfaction with the IEC 60439 series. The purpose was to harmonise and define all general requirements for low-voltage electrical ASSEMBLIES.

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. In order to conform to the standard, type tests have been replaced by a design verification which can be carried out by the three following equivalent and alternative methods: testing, calculation/measurement or application of design rules.
