The older IEC 60439 standard categorized panels as either Type-Tested Assemblies (TTA) or Partially Type-Tested Assemblies (PTTA). This caused ambiguity in compliance. IEC 61439 eliminated these terms entirely, replacing them with a unified process.

Defines how internal compartments separate busbars, functional units, and terminals to protect against accidental contact and limit internal arc propagation. 2.

IEC 61439-2 is the part of the standard that deals with low-voltage switchgear and controlgear assemblies - Part 2: Power distribution units (PDUs). This section provides specific requirements for the design, construction, and testing of power distribution units (PDUs), which are used to distribute power to various loads in a low-voltage power distribution system.

Applies to assemblies with a rated voltage not exceeding 1000 V AC or 1500 V DC. Covers both enclosed and open assemblies.

You cannot apply IEC 61439-2 alone. Every clause in Part 2 references the corresponding clause in Part 1. Therefore, having the IEC 61439-1 and -2 PDF together is essential for full compliance.
