High-voltage fuse links provide protection in medium-voltage systems. Their big selling point is their ability to interrupt short circuits extremely quickly. That effectively protects equipment and components from the dynamic and thermal effects of short circuits. SIBA HV fuses protect every stage of the power supply: from long-lived fuses featuring ICS technology in wind turbines to protection devices for large transformers or other energy generation and distribution systems in the 3 to 40.5 kilovolt range.

Power semiconductors: Without the high-tech developments in the field of converters, thyristors or UPS, today's energy supply would be unthinkable. As important as these devices are, they are also highly sensitive to short-circuit currents.

It is therefore reassuring to know that SIBA makes fuses that work so fast they are able to protect these semiconductors and so keep them working for very much longer. The name of this product range is "Ultra-rapid". They separate your investment from the power supply quickly and reliably. And we have designed them in such a way that even after a long time in service under constantly changing operating loads, they still maintain their condition. For we know that every tenth of a second counts if your semiconductor is to be kept safe from harm ...

Measurement devices, sensors and machine controls – industrial electronics are the nerve system of the commercial economy, which is why this technology is scoring one success after another. Complex and in some cases extremely miniaturised devices and equipment communicate closely with one another to ensure that everything works exactly as it should. Elaborate programming guarantees that all the different cogs in the production machinery work together smoothly.

Equipment of this kind needs special protection: SIBA safety fuses are designed to ensure that if the worst comes to the worst your components will have a soft landing. Which means no damage is done to the electronics

Low-voltage high-breaking-capacity fuses are used wherever high and medium voltage is stepped down for users: switchgear, control cabinets, large electric machines, residential and commercial service entrances with voltages ranging from 250 to 1600 volts. SIBA LV fuses provide solid protection from damage caused by faults in the electrical equipment or mistakes made during installation.
