Partly due to the fluctuating energy prices and increasing grid congestion in the Netherlands, battery systems are becoming increasingly popular. As also described in PGS37.1, this entails risks.

Short-circuit currents of battery systems can be particularly high. It is therefore important to make a good short-circuit current calculation, and to lay out all components accordingly. Not only your fuses must be able to withstand the short-circuit current, but also your DC bus and associated components.

CRG offers different types of fuses for battery systems. Both gBat, aBat and aR, in different classes and shapes. From 500V to 1000V and even 1500V. Cylindrical fuses, but also square body with different mounting methods for bolt and blade mounting.

More and more charging stations and squares are being built at a rapid pace. Charging speeds are also increasing, due to increasing voltages and currents of charging stations and battery packs of EVs. This requires high-quality safety systems. A short circuit in the charging circuit can cause an enormous short-circuit current.

This also applies to inverters in ships, DC grids and electrolysers, for example.

We understand that design, heat generation, high voltages and short circuit resistance can be a challenge when selecting DC fuses. That is why we offer types and different shapes.
