Siba fuses | Ultra-rapid (URA)

Description

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.
