Understanding AS/NZS 61439: The New Standard for Low-Voltage Switchgear and Controlgear Assemblies
The AS/NZS 61439 standard represents a significant evolution in the regulation of low-voltage switchgear and controlgear assemblies in Australia and New Zealand. Introduced to replace the older AS/NZS 3439 standard, AS/NZS 61439 aligns closely with the international IEC 61439 series, incorporating specific modifications to address local requirements. This new standard aims to enhance the safety, reliability, and performance of electrical assemblies, ensuring they meet the highest quality benchmarks. Furthermore adherence is mandatory. As set out in AS/NZS 3000.
One of the key changes in AS/NZS 61439 is the shift from the concept of Type Tested Assemblies (TTA) and Partially Type Tested Assemblies (PTTA) to a more comprehensive design verification process. This process includes distinct design verifications that cover both constructional and performance aspects, replacing the seven type tests of the previous standard. These verifications ensure that all assemblies are rigorously tested for factors such as resistance to corrosion, mechanical impact, and dielectric properties, thereby reducing the risk of failures and enhancing overall safety.
Moreover, AS/NZS 61439 clearly delineates the responsibilities between the original manufacturer and the assembly manufacturer, providing a more structured framework for compliance. This clarity helps in mitigating legal, safety, and financial risks associated with the manufacturing process. For businesses and contractors, understanding and implementing the requirements of AS/NZS 61439 is crucial for ensuring that their electrical assemblies are not only compliant but also optimized for performance and safety in various applications, from residential to industrial settings.
By adopting AS/NZS 61439, the industry is moving towards a more standardized and reliable approach to low-voltage switchgear and control gear assemblies, fostering innovation and ensuring that safety standards keep pace with technological advancements.
