Optimal protection of BESS systems
260kA breaking capacity – maximum protection for high-capacity battery storage 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.
Our response: Fuse-links with 260kA at 1500V DC
Through targeted enhancements to the aBat and gBat utilization categories, we have adapted our fuse-links to meet these requirements. The result: currently the highest rated breaking capacity on the market.
- 260kA at 1500V DC
- Maximum system safety at high DC currents
- Future-proof design for scalable BESS architectures
- Certified according to cRUus
This new utilization category not only enhances safety, it also gives you greater design flexibility, compliance to standards and long-term technological viability

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.

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.
