Optimal protection of BESS systems
CURRENTLY THE STRONGEST: Our fuse-links set new standards – with a rated breaking capacity of up to 260kA at 1500V DC.
As battery energy storage systems (BESS) are rolled out worldwide, demands are increasing not only in terms of efficiency and capacity, but also regarding short circuit protection. Modern storage systems place the highest demands on fuse-link technology, as short circuit currents in the range of several hundred kA can occur. SIBA addresses this challenge by conducting tests in internationally recognized laboratories and is already testing BESS fuse-links at currents of up to 260kA.
Interview
The challenge: Rising risks as power levels increase
The trend towards larger and more powerful systems is being driven largely by government funding programs, the energy transition, the expansion of renewable energy and the growing need for grid stability. This highlights the need for an extremely robust and reliable protection strategy – both for new projects and for scaled-up existing installations, as the potential risk of faults increases as the number of storage units grows.

2000V DC architectures – the new standard for battery storage systems?
The demands placed on modern battery storage solutions are growing rapidly: greater capacity, higher efficiency and lower system costs. In this context, the focus is shifting to the next stage of technological development –
2000V DC. While 1000V and 1500V systems have long been regarded as the standard, higher voltage levels are emerging as the logical next step: They enable more compact architectures and open up
new possibilities for system design.
More and more manufacturers and system integrators are looking into higher voltages. However, as voltages increase, so do the demands placed on safety concepts, component development and
system architecture. Our experts have been working on 2000V DC architectures since the early stages of development – driven by conviction and with a long-term vision.

In our specialist testing and development facilities, we make sure that every fuse-link delivers what it promises. From non-destructive testing using X-ray technology and climatic stress tests to practical process optimization in the Innovation Lab: Our measures ensure the highest reliability – even under extreme conditions. Discover how we make the difference with state-of-the-art infrastructure.
X-ray imaging device
A look inside
We inspect the internal structure of our fuse-links using state-of-the-art X-ray technology, non-destructively and with precision. In the process, key characteristics such as fuse-link conductor geometry, positioning, and solder joints are monitored directly during production. Where conventional visual inspection reaches its limits, X-ray technology enables reliable evaluation of hidden structures. This method also helps to identify potential faults at an early stage and ensures consistently high product quality, even in new production processes. This is how we ensure that our fuse-links consistently meet our customers’ high standards due to continuously optimized development processes.
Climate chamber
Precision for demanding operating conditions
In our climate chamber, we simulate various environmental conditions such as temperature, humidity and stress cycles – tailored to the specific requirements of customers. Our tests go beyond the standard requirements, as we are also able to test outside the usual commercial ambient temperature ranges. This is how we test all types of fuse-links under realistic and extreme conditions. These tests enable us to identify weaknesses at an early stage and specifically optimize our products. Customers benefit from fuse-links that continue to function reliably even in changing or extreme environments. By conducting our own tests we are able to respond flexibly to specific customer requirements, thereby ensuring highest standards of quality and safety.
SIBA Laboratory
Quality reliably tested
In its in-house laboratory, SIBA carries out extensive testing on fuse-links, including characteristic curve and cycle tests, temperature rise measurements and environmental and stress tests. The aim is to ensure that our products function properly and can withstand the stress of real-world conditions.
The laboratory plays a key role in the early-stage development of new fuse-links. This allows initial samples to be tested under real-world conditions without causing delays in the production process. As part of its ongoing quality assurance procedures, the laboratory supplements production checks with random sampling tests in accordance with defined standards.
This means customers benefit from consistently high quality standards, rapid response times and the ability to accurately validate specific requirements. The laboratory lays the foundations for innovative, reliable products – and strengthens confidence in our solutions.
Tip from the experts
Fuse-link selection for BESS – the key factors for safe battery storage systems
As large-scale battery storage systems become more widespread, specifying the right fuse-links is becoming increasingly complex and, at the same time, ever more decisive. Rising DC voltages, higher short circuit currents, thermal stresses and multi-level system architectures, from module level to bank level, are placing new demands on protection concepts. Inadequate fuse-link selection can significantly compromise availability, safety and compliance with standards.
This guide sets out, in four clearly structured steps, how modern BESS systems can be protected in a selective, compliant and future-proof method.
