What is BS EN 60947-6-2:2003+A1:2007?

BS EN 60947-6-2:2003+A1:2007 is an electrical standards document that provides specifications and guidelines for low-voltage switchgear and controlgear contacts. It is part of the EN 60947 series, which covers a wide range of electrical equipment used in industrial applications.

The Purpose of BS EN 60947-6-2:2003+A1:2007

The primary purpose of this standard is to ensure the safe and reliable operation of switchgear and controlgear contacts. These components are critical in controlling the flow of electricity in a wide variety of industrial machinery and systems. The standard sets out specific requirements for the design, construction, performance, and testing of these contact devices.

Key Specifications and Requirements

The BS EN 60947-6-2:2003+A1:2007 standard defines various technical parameters and requirements for switchgear and controlgear contacts. Some of the key specifications include:

Contact ratings: The standard specifies the maximum operational voltage and current levels for different types of contacts. This ensures that the contacts can safely handle the expected electrical loads.

Temperature rise limits: To prevent overheating and damage, the standard sets limits on the temperature rise of contacts during normal operation.

Mechanical durability: The standard defines the number of mechanical operations (opening and closing cycles) that contacts should be able to withstand without excessive wear or failure.

Electrical endurance: Contacts are tested to ensure their ability to maintain proper electrical connection over a specified number of operations.

Compliance and Certification

Manufacturers of switchgear and controlgear contacts typically strive to comply with the BS EN 60947-6-2:2003+A1:2007 standard to ensure the quality and reliability of their products. Compliance with this standard can be demonstrated through testing and certification processes conducted by accredited third-party laboratories.

Electrical equipment that meets the requirements of the standard carries a certification mark indicating compliance. The use of certified components provides assurance to end-users that the equipment they purchase meets the necessary safety and performance standards.

In conclusion, BS EN 60947-6-2:2003+A1:2007 plays a crucial role in ensuring the safe and reliable operation of switchgear and controlgear contacts used in industrial applications. By defining specific technical requirements and testing procedures, this standard helps manufacturers produce high-quality electrical components that meet the expected performance and safety standards.
