In the modern world, electricity powers our lives, from the lights that brighten our homes to the intricate machinery driving industries forward. Yet, with such reliance on electricity, safety is paramount. To ensure the utmost safety and reliability of electrical systems, international standards are established. One such critical standard is the IEC 61439, and in this blog, we’ll take a deep dive into what it entails and how Modutec embraces it to guarantee electrical safety.
Understanding IEC 61439: Setting the Safety Benchmark
IEC 61439 is the international standard that governs low-voltage switchgear and controlgear assemblies. These assemblies are the backbone of electrical systems, encompassing the array of components, including switches, meters, and more, responsible for controlling, measuring, and protecting electrical circuits. Essentially, they ensure that electricity flows reliably and safely where it’s needed.
This standard was introduced as a response to the evolving needs of the electrical industry. Its predecessor, IEC 60439, while effective, had its limitations. IEC 61439 was developed to provide a more comprehensive, adaptable, and rigorous framework for ensuring the safety and reliability of electrical assemblies.

The Key Shift: Design Verification
One of the most significant shifts from IEC 60439 to IEC 61439 is the move from type testing to design verification. Under IEC 60439, assemblies were tested to see if they met specific requirements. IEC 61439, on the other hand, emphasizes a thorough design verification process, which can be executed through three equivalent methods: testing, comparison/calculation/measurement, or application of design rules/assessment. This shift allows for more flexibility while ensuring that the design itself is robust and reliable.
Modutec’s Commitment to Safety
Modutec, a leading name in electrical solutions, has embraced the IEC 61439 standard with open arms. Our LV modular switchboard enclosure systems have been repeatedly Type Tested as per IEC 61439 Part 1 & 2. These tests cover a wide range of aspects, from the strength of materials to dielectric properties, ensuring that our products meet the stringent safety and reliability requirements set by the standard.
