What is BS EN 60947-4-2016?

BS EN 60947-4-2016 is a technical standard that specifies the requirements for low-voltage switchgear and controlgear assemblies. It provides guidelines for the design, testing, and performance of these electrical devices. This standard is used by manufacturers to ensure that their products meet safety and performance standards.

The Purpose of BS EN 60947-4-2016

The main purpose of BS EN 60947-4-2016 is to enhance the safety and reliability of low-voltage switchgear and controlgear assemblies. It sets out the requirements for insulation, temperature rise, clearance distances, and protection against electric shock. Compliance with this standard ensures that the equipment can operate safely under normal conditions and during fault conditions.

Key Requirements of BS EN 60947-4-2016

One of the key requirements of BS EN 60947-4-2016 is the coordination between protective devices within an assembly. This means ensuring that if one device, such as a circuit breaker, trips due to a fault or overload, it doesn't affect the operation of other devices in the assembly. This coordination helps prevent further damage and disruption to the electrical system.

Another important requirement is the ability of the assembly to withstand short-circuit currents. BS EN 60947-4-2016 specifies the minimum short-circuit current rating for different types of assemblies, ensuring that they can handle high fault currents without endangering personnel or damaging the equipment.

Benefits of BS EN 60947-4-2016

BS EN 60947-4-2016 benefits both manufacturers and end-users of low-voltage switchgear and controlgear assemblies. For manufacturers, compliance with this standard ensures that their products meet safety and performance requirements, enhancing their reputation in the market. End-users benefit from the increased safety provided by these compliant assemblies, reducing the risk of electrical accidents and system failures.

Additionally, adherence to BS EN 60947-4-2016 facilitates international trade, as it harmonizes the standards used by different countries. Manufacturers can design and produce assemblies that meet this global standard, eliminating the need for multiple product variations based on regional specifications.

In conclusion, BS EN 60947-4-2016 is a technical standard that sets out the requirements for low-voltage switchgear and controlgear assemblies. Its purpose is to enhance safety and reliability. Compliance with this standard ensures that the equipment operates safely and efficiently. It benefits both manufacturers and end-users and facilitates international trade. By following this standard, the electrical industry can maintain high levels of quality and safety.
