IEC 61439-2: Power Switchgear and Controlgear Assemblies (PSC-Assemblies)

One of the biggest shifts introduced by the IEC 61439 standard is the clear division of responsibility between the two types of manufacturers:

IEC 61439 is a series of standards that replaces the older IEC 60439, which was first published in 1970. The new series, published in 2008, comprises several parts, with IEC 61439-1 and 2 being the most relevant. These standards outline the requirements for low-voltage switchgear assemblies, which are essential components in electrical distribution systems. iec 614391 and 2 pdf

Sourcing official, compliant documentation like the standards guides engineering teams through flawless system integration.

Engineers should purchase authorized copies of these PDF standards directly from the or their local national standards body (such as BSI, DIN, or AFNOR) to ensure they have the latest amendments and active technical sheets. Engineers should purchase authorized copies of these PDF

IEC 61439-1 lays down the general definitions, service conditions, construction requirements, technical characteristics, and verification requirements for low‑voltage switchgear and controlgear assemblies. This document applies to low‑voltage switchgear and controlgear assemblies (referred to as "ASSEMBLIES" in the standard) only when required by the relevant assembly standard that follows it.

Meets national grid and building regulations globally.

Here are the specific scopes:

Validating that moving parts, interlocks, and handles perform a specified number of operations without failure. 5. Routine Verification (Testing Individual Panels)
