IEC 61499-1 is the general standard for Low-Voltage Switchgear and Controlgear Assemblies (ASSEMBLIES). It applies to assemblies with a rated voltage not exceeding 1000 V AC or 1500 V DC. There are five legitimate ways to get the
This standard represents a significant shift from the previous IEC 60439 series. While the old standard focused on "Type Tested Assemblies" (TTA) and "Partially Type Tested Assemblies" (PTTA), IEC 61439-1 introduces the concept of "Design Verification."
The standard aims to ensure that an assembly meets the required safety and performance criteria through rigorous verification of design and routine checks during manufacturing. IEC 61499-1 is the general standard for Low-Voltage
The entity that takes responsibility for the finished assembly. The manufacturer is responsible for the design verification and the routine verification of every unit produced.
