What is EN 60947-1:2015?

Introduction

The EN60947-1:2015 is a technical standard that sets out the requirements for low-voltage switchgear and controlgear assemblies. It provides guidelines and safety measures to ensure the proper functioning and protection of electrical equipment in various applications.

Scope and Objectives

The standard applies to low-voltage switchgear and controlgear assemblies used in industrial, commercial, and residential settings. Its primary objective is to guarantee the safety and functionality of these assemblies during normal operation, as well as during fault conditions.

Main Features and Requirements

The EN60947-1:2015 defines several important features and requirements for switchgear and controlgear assemblies. These include:

Rated operational voltage: The standard specifies the maximum voltage at which the assembly can safely operate.

Short-circuit current rating: It defines the ability of the assembly to withstand and interrupt short-circuit currents without suffering damage.

Temperature rise limits: This requirement ensures that the temperature within the assembly remains within acceptable levels to prevent overheating and fire hazards.

Clearances and creepage distances: The standard sets out minimum distances between live parts and conductive surfaces to prevent electric shocks and flashovers.

Isolation and switching: It includes specifications for isolating power sources and the ability to perform safe switching operations.

Conformity assessment: The standard mandates that switchgear and controlgear assemblies undergo testing and certification to ensure compliance with the requirements.

Benefits of Compliance

Adherence to the EN60947-1:2015 standard offers several benefits. It ensures the safety of personnel working with electrical installations, reduces the risk of electrical accidents, and minimizes the likelihood of equipment failure or damage. Additionally, complying with the standard promotes compatibility and interoperability, facilitating the integration of different components and systems within an electrical installation.

Conclusion

The EN60947-1:2015 standard is a vital document in ensuring the safety, functionality, and compatibility of low-voltage switchgear and controlgear assemblies. By adhering to its guidelines, organizations can create a safer working environment and reduce the chances of equipment failures or accidents. It is crucial for manufacturers, installers, and end-users to understand and implement this standard to guarantee the proper functioning and protection of electrical equipment in various applications.
