What is BS EN 61439-2:2009?

BS EN 61439-2:2009 is a technical standard that provides requirements and guidelines for the design, construction, and testing of power switchgear and control gear assemblies. It applies to low-voltage switchgear and control gear assemblies intended to be used in electrical installations.

Design and Construction Requirements

This standard sets out the design and construction requirements for power switchgear and control gear assemblies. It covers aspects such as electrical continuity, protection against electric shock, insulation coordination, and clearances distances. By complying with these requirements, manufacturers ensure that their products are safe, reliable, and meet industry standards.

Testing and Verification

BS EN 61439-2:2009 also defines the testing and verification procedures that need to be carried out on power switchgear and control gear assemblies. These tests include temperature-rise tests, dielectric tests, and short-circuit withstand tests. Compliance with these tests ensures that the assemblies can handle the expected electrical loads without failure.

Benefits of Compliance

Complying with BS EN 61439-2:2009 offers various benefits for both manufacturers and end-users. Manufacturers can be assured that their products meet internationally recognized safety and reliability standards, which enhances their reputation and marketability. For end-users, using compliant switchgear and control gear assemblies means increased safety and reduced risk of electrical hazards.

Furthermore, compliance with this standard ensures compatibility and interoperability between different manufacturers' products, allowing for easy integration into electrical systems.

In conclusion, BS EN 61439-2:2009 is a crucial technical standard that sets out the requirements and guidelines for the design, construction, and testing of power switchgear and control gear assemblies. Compliance with this standard ensures safety, reliability, and compatibility in electrical installations.
