What is BS EN 60947-4-2:2012?

BS EN 60947-4-2:2012 is a technical standard that sets forth requirements for low-voltage switchgear and controlgear, specifically focusing on circuit-breakers and contactors. This standard was introduced by the British Standards Institution (BSI) in 2012, and it has since become widely recognized and used internationally.

Scope and Application

The scope of BS EN 60947-4-2:2012 applies to electrical equipment operating at voltages not exceeding 1,000 V AC or 1,500 V DC, and intended to be installed in electrical installations or used as industrial equipment.

This standard is primarily applicable to circuit-breakers and contactors used for switching, but it also covers the requirements for associated control, measuring, signaling, and protection devices used within the electrical circuits.

Compliance and Testing

To ensure compliance with BS EN 60947-4-2:2012, manufacturers need to undergo various testing procedures. These tests include verification of mechanical structure, dielectric properties, thermal performance, and electrical operation under both normal and abnormal conditions.

Furthermore, this standard provides guidelines for type testing, routine testing, and production testing, ensuring that the electrical equipment meets the specified requirements throughout its lifespan.

Benefits and Importance

BS EN 60947-4-2:2012 plays a crucial role in ensuring the safety, reliability, and performance of low-voltage switchgear and controlgear, which are widely used in residential, commercial, and industrial applications.

By adhering to this standard, manufacturers can confidently deliver products that meet the necessary quality and safety standards. Users of electrical equipment can have peace of mind knowing that the products they are installing comply with the requirements, reducing the risk of hazards and electrical accidents.

Overall, compliance with BS EN 60947-4-2:2012 promotes harmonization and consistency in the design, production, and use of low-voltage switchgear and controlgear across different countries and industries.

This technical standard is a valuable tool that ensures the safety and reliability of electrical equipment. Adherence to BS EN 60947-4-2:2012 not only benefits manufacturers but also provides assurance to end-users, ensuring that their electrical installations meet the necessary standards for performance and safety.
