What is EN 60947?

EN60947 is a set of international standards for low-voltage switchgear and controlgear. These standards are crucial for ensuring the safety and proper functioning of electrical equipment used in various industries, including power distribution, manufacturing, and infrastructure.

Importance of EN60947

Compliance with EN60947 is essential to guaranteeing the reliability and safety of electrical installations. These standards establish requirements for design, performance, and testing of low-voltage switchgear and controlgear, encompassing a wide range of products like circuit breakers, contactors, motor starters, and switch disconnectors.

The importance of adhering to these standards cannot be overstated, as non-compliance may lead to serious malfunctions, accidents, or even fatalities. By following EN60947, manufacturers and users can ensure the durability, efficiency, and reliability of their electrical systems.

Key components of EN60947

EN60947 covers various aspects of switchgear and controlgear, including:

General rules for testing and rating: This section establishes uniform testing procedures and criteria for determining the ratings of different equipment. It ensures that the devices meet specific performance and safety requirements.

Clearances and creepage distances: These parameters define the minimum distances between conducting parts and between conducting parts and accessible surfaces. They prevent electrical arcing and ensure safe isolation between conductive elements.

Electrical and mechanical endurance: This clause specifies the number of operations or cycles that switchgear and controlgear can perform under normal operating conditions without any failure. It helps determine the lifespan and reliability of the equipment.

Short-circuit withstand strength: This part ensures that the equipment can withstand high short-circuit currents without suffering any damage or creating hazards.

Benefits of EN60947 compliance

Complying with EN60947 offers several benefits:

Safety assurance: By adhering to these standards, potential electrical hazards and accidents can be minimized, ensuring a safe working environment for personnel.

Product reliability: Products compliant with EN60947 are designed and tested to meet stringent performance requirements, ensuring their reliability and long service life.

Global acceptance: EN60947 is an internationally recognized standard, enabling manufacturers to export their products with ease, knowing they comply with widely accepted regulations.

Legal compliance: In many countries, compliance with recognized standards like EN60947 is mandatory. Non-compliance may lead to legal consequences and hinder business operations.

In conclusion, EN60947 plays a vital role in ensuring the safety, functionality, and reliability of low-voltage switchgear and controlgear. Adhering to these standards not only helps businesses meet legal requirements but also ensures the well-being of users and longevity of electrical systems.
