Why It Matters for Your Low-Voltage Switchboards
Not all switchboards are equal when it comes to low-voltage power distribution. In modern industrial environments, safety, reliability, and IEC compliance are paramount. Following standards like IEC 61439 ensures quality of LV switchgears, panels, and assemblies, and it has been adopted by manufacturers across the Globe.
Their absence can cause costly downtime in both operational and financial terms. This is where type-tested assemblies (TTA), such as SIVACON S8 from Siemens, can make a major difference.

What does “Type-Tested” Mean?
The term type-tested usually refers to a representative sample, a prototype of the product that has undergone a series of comprehensive tests to confirm that the design & construction characteristics comply with a specific standard, specification, or regulation. The term type-tested assembly low-voltage switchgear means that the system has been verified according to the IEC 61439 standard.
This standard is a successor to IEC 60439, and it defines the set of requirements for the design, construction, and verification of all low-voltage switchgear and controlgear assemblies, with the primary purpose of ensuring safety, reliability, and consistency.
The main difference between type-tested and custom-built, non-tested panels is that a type-tested switchboard guarantees that all components are validated together under the real operating conditions. That includes busbars, protection devices, enclosures, and interconnections.
Each type-tested design undergoes a comprehensive test for:
- Temperature conditions - Temperature rising and heat dissipation
- Dielectric properties (insulation with voltage withstand)
- Short-circuit Withstand
- Mechanical operation & endurance
- Protection degree (IP rating) & clearances
These tests are used to confirm that the switchboard can perform safely & reliably in actual industrial environments. Additional safety is provided with a modular arc fault protection system tested according to IEC/TR 61641. This standard guides testing low-voltage switchgear assemblies for internal arc faults and their ability to protect personnel and properties. It ensures a higher level of personnel and switchboard safety under conditions of internal arcing. It makes SIVACON S8 a perfect fit for demanding applications, like on ships or in regions with a greater risk of earthquakes.
Why does it matter?
When you choose a type-tested switchboard, that ensures:
- Compliance with international standards (IEC 61439, IEC/TR 61641)
- Increased operational safety for personnel and equipment
- Predictable performance and easier certification for End-users
- Reduced risk of downtime caused by design or assembly errors
- Simplified maintenance and expansion, thanks to standardized components and layouts
In other words, meeting regulations and complying with standards builds confidence in your entire electrical infrastructure.
