What is EN 60947?

EN60947, also known as IEC 60947, is a series of international standards that define the requirements for low-voltage switchgear and controlgear assemblies. These standards are crucial in ensuring the safety, integrity, and performance of electrical equipment used in various industrial and commercial applications.

The Purpose of EN60947

The primary purpose of EN60947 is to establish common guidelines and specifications for manufacturers, system integrators, and end-users. It sets forth the technical requirements necessary to achieve reliable and safe operation of switchgear and controlgear assemblies. Compliance with EN60947 ensures that electrical installations meet established standards and reduce the risks associated with electrical faults, such as short circuits or overloads.

Key Components and Features

EN60947 covers a wide range of products, including circuit-breakers, switches, contactors, motor starters, and more. Some key components and features addressed by this standard include:

Circuit-breaking capacity: EN60947 specifies the maximum current level that a device can safely interrupt under specific conditions.

Electrical endurance: This standard defines the number of switching operations a device can perform without losing its performance or risking failure.

Temperature rise limits: EN60947 sets limits on the temperature rise of switchgear and controlgear assemblies, ensuring they operate within safe thermal limits and preventing damage to surrounding equipment.

Clearances and creepage distances: These requirements dictate the minimum space needed between conductive parts to prevent arcing or accidental contact.

Benefits of EN60947

Compliance with EN60947 provides several benefits for both manufacturers and end-users. For manufacturers, conforming to this standard ensures their products meet internationally recognized quality and safety requirements. Additionally, it enables them to access global markets since many countries require compliance with EN60947 for electrical equipment.

For end-users, adherence to EN60947 guarantees the quality and reliability of installed equipment. It offers peace of mind, knowing that the switchgear and controlgear assemblies have been rigorously tested and certified. Compliance also helps in reducing workplace accidents and electrical failures, improving overall operational efficiency, and minimizing downtime due to equipment malfunctions.
