Our fuses provide safety. For your values. Dependably. So that you can focus on your core business with an easy mind. Our Protection. Your Benefit.

Our aspiration – Your advantage All we think about is fuses. And in doing so, we save your resources. For over 60 years now, SIBA has specialised in fuses – from miniature devices for electrical components to high-voltage installations. And because we devote ourselves uncompromisingly to our specific core business, you can be sure that our fuses will work when needed. Through our products, we safeguard your products, your plant and machinery, and above all your personnel. So seen from that angle, what we really think about are your vital resources. As you can see, SIBA fuses are not C products,...

Other fuses Special fuses are our trade SIBA holds over 10,000 different fuse technology products. But even with that variety, we can still not cover every application, and for constantly changing needs we have to develop ever new variants. And even if one fuse fits perfectly, it may still not be able to be used because – to give just one example – a specific operating sequence may be required in the case of fuses installed in series. Nevertheless, we also have a wide variety of pre-made products available for special applications – from mining to the railways.

The cradle for our development: Fuses for the mining industry Our company had its cradle in the mining industry, and it was fuses for use in mining, where the requirements in terms of safety and equipment protection are exceptionally high, that made us great. And even if we now offer an abundance of products for all kinds of applications – SIBA still supplies fuses for the mining industry. In time-tested quality. For time-tested safety. Shock-proof: Fuses for shipping and the railways In the field of shipping and on the railways around the world, the specific requirements in the field of fuse...

Miniature fuses The rip cord for industrial electronics Measuring equipment, sensor technology, machine controls – industrial electronics are the nervous system of manufacturing industry and constitute a continuous sequence of high-flying developments. Complicated, sometimes extremely miniaturised devices and fittings working in close communication with one another ensure that everything works as it is supposed to. Complex programming ensures that the many cogs in the production machinery all work smoothly together. Equipment with such an important role also needs special protection: SIBA miniature...

Extensive portfolio, own production The very smallest of our miniaturised fuses covers an area of less than two square millimetres, though our range of electronic component fuses also includes veritable “giants”, with a length of 150 mm. So whether self-resetting PTC, classical constructions or SMD types for soldering onto printed circuit boards or tiny fuses for slotting into them: our warehouse holds a fuse in store that is just right for you. And what we don’t already have available, we can make. In accordance with your specifications. We take the protection of your equipment seriously. Classical...

Low-voltage fuses Optimum protection for mains and equipment A switchgear without proper fuse protection may well be put out of service for a considerable time. And that can be expensive. And even if the actual damage is covered by the insurance, the outage may cause an order to be lost, and nobody except you will pay for all the trouble and work involved. So seen from this angle, optimum fuse protection is a very worthwhile investment. If the worst comes to the worst, the fuse operates in a sufficient time, is quickly replaced, and work can then carry on as before. But also at home and in other...

Low voltage (NH): Protection à la carte Whether as a pre-fuse in the house connection box or as protection for machine tools in the factory – our NH products cover a wide variety of applications. They are available for a large number of different characteristics, for all normal sizes and for many different voltages. We are constantly adding new innovations to our broad product range – such as the combination indicator. This shows both at the top and in the centre whether the fuse has been tripped. Optimum protection and optimised handling add up to maximum utility. NH combination indicator: A...

High-voltage fuses We keep up the tension Power stations, substations, overhead power lines: Of the many energy utility installations that ensure our vital electricity supply, most people only take notice of the big, visible features. As far as many consumers are concerned, electricity still simply comes out of the wall. But that things are far from that simple is a story the energy utilities could tell every day. But to prevent matters from reaching a pitch where people notice that something is wrong because the power has failed, the operators take precautions by investing in good time, and...

Transformers under observation Power transformers are highly sophisticated, motionless electric machines. The start-up process is also a highly sophisticated matter, involving high currents, but without causing the fuse to trip. On the other hand, though, the power circuit must be reliably interrupted if excessively high currents flow for an excessively long time. In this particular area, standards can provide general recommendations only – but thanks to our many years of experience, we know exactly what fuse is needed to take care of what situation. Fuses that go a long way to protect your motors...

Ultra-rapid fuses When every tenth of a second counts 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...
