: Issued by third-party laboratories (LOVAG, DEKRA, Intertek).
The standard applies to low-voltage busbar trunking systems used in industrial, commercial, and residential buildings. It covers:
Experts highlight several critical areas of focus within the standard:
Comprehensive Guide to IEC 61439-6: Low-Voltage Busbar Trunking Systems (BTS) iec 61439-6 pdf
: Testing insulation integrity using power-frequency withstand voltage and impulse withstand voltage.
A busbar trunking system is a complex assembly, and IEC 61439-6 breaks down its essential elements into clear, technical requirements. The standard outlines all necessary performance characteristics, from electrical data (rated current, insulation voltage, short-circuit withstand strength) to physical data (dimensions, weight) and even the maximum permissible temperature rises under full load.
This standard specifies requirements for busbar trunking systems used in power distribution for industrial, commercial, and similar applications. It applies to systems with rated voltages up to or 1,500 V DC . A busbar trunking system is a complex assembly,
IEC 61439-6 is specifically focused on busbar trunking systems, which are used to distribute electrical power in buildings, industrial facilities, and other applications. Busbar trunking systems consist of a series of connected busbars that carry electrical current, and are often used in place of traditional cable-based distribution systems.
Designed for general use as well as special conditions, such as those found in ships, rail vehicles, and domestic applications where unskilled persons may operate the equipment.
Indoor or outdoor use, typically in industrial, commercial, or residential infrastructures. 2. Construction Requirements It applies to systems with rated voltages up
The previous standard (IEC 60439-2) relied heavily on the concepts of "Type-Tested Assemblies" (TTA) and "Partially Type-Tested Assemblies" (PTTA). IEC 61439-6 completely eliminates these categories. It replaces them with a strict verification process requiring every system to be verified through testing, calculation, or design rules. 2. Key Technical Definitions and Parameters
Consulting engineers writing specification documents for mega-projects (data centers, commercial towers, industrial plants) need the exact wording of IEC 61439-6 to mandate that all installed busways are certified. Verification of Test Certificates
Compliance cannot be assumed; it must be proven. IEC 61439-6 outlines three distinct paths to verify design requirements.
