What is EVS EN IEC 61439 1 ?

The IEC 61439 standard is a technical specification that provides safety and performance guidelines for low-voltage switchgear and controlgear assemblies. It is developed by the International Electrotechnical Commission (IEC) and aims to ensure the proper functioning and reliability of electrical distribution systems.

Key Requirements

The key requirements of EVSEN/IEC 61439-1 are as follows:

Safety: The assemblies must ensure the safety of personnel and property.

Reliability: The assemblies must be reliable and operate without failure for a specified period.

Performance: The assemblies must perform as specified in the standard.

Verification and validation: The assemblies must be verified and validated to ensure that they meet the requirements of the standard.

Key Features of IEC 61439

The IEC 61439 standard has several key features that make it an essential standard for the design and construction of low-voltage switchgear and controlgear assemblies. These features include:

Safety-critical applications: The standard is designed to ensure the safety of personnel and property in applications where electrical shock, fire hazards, and equipment failure are a concern.

Performance: The standard provides performance requirements for the switchgear and controlgear assemblies, ensuring that they are reliable and perform as specified.

Verification and validation: The standard requires that the switchgear and controlgear assemblies be verified and validated to ensure that they meet the requirements of the standard.

IEC 61439-1 compatibility: The standard is designed to be compatible with IEC 61439-2, which ensures that it does not conflict with other standards.
