Protect your systems and electrical devices against excessively high voltage peaks caused by switching operations and lightning strikes.

You should plan your protection concept for lightning and surge protection so that all cables, devices, and systems are protected.

The protective circuit principle is easy to illustrate: Draw an imaginary circle around the object you want to protect. Surge protective devices must be installed at all points where cables intersect this circle. This ensures that the area within the protective circuit is protected in such a way that conducted surge voltages are prevented. An effective protective circuit helps ensure seamless surge protection.


Our power supplies, DC/DC converters, redundancy modules, and uninterruptible power supplies enable you to supply your application reliably.
Choose the ideal power supply that meets your needs from our wide range of different product families. DC/DC converters and DC/AC inverters are available for voltage conversion. Our redundancy modules enable you to decouple two power supplies and ensure the high availability and productivity of your system. You can rely on our uninterruptible power supplies (UPS) during mains interruptions. With these, you are not taking any risks.

In addition, energy measuring devices with the appropriate sensor technology enable you to record energy flows in detail and assess the power quality.

Device circuit breakers protect your equipment against overload and short-circuit currents and selectively shut down just the affected circuit in the event of a fault.
To provide the ideal protection, our circuit breakers therefore use various technologies:

  • Thermal circuit breakers for overload protection
  • Thermomagnetic circuit breakers for overload and short-circuit protection
  • Electronic circuit breakers for protection in the event of overload, short circuit, line attenuation, and high input capacitance

Optimize your production process and minimize downtimes by using our overcurrent protection.

More efficiency in system operation

Efficient and sustainable processes are becoming increasingly important. In production, as well, it is important to optimize energy consumption and reduce carbon emissions – without losing productivity. With the help of our energy monitoring solutions, you can record energy consumption and derive efficiency measures.

Your advantages

  • Cost savings through lower consumption and more efficient processes
  • Careful use of resources
  • Reduction of carbon emissions
  • Compliance with the ISO 50001 energy management standard
