Industrial plants and building infrastructures are becoming increasingly complex. This makes them more sensitive to surge damage. In addition, digitalization is increasing the number of connections and data streams that must not be interrupted. Reliable lightning and surge protection ensures system availability, protects against data loss, and increases added value.
Weidmüller has had standard-compliant lightning and surge protection products in its range for many years and develops customized surge protection solutions with maximum reliability. The proven surge protection devices of the VARITECTOR series are available for power systems, I&C components, and data interfaces.
VARITECTOR surge protection devices reliably prevent lightning and surge damage. They comply with international standards and offer maximum investment protection.
VARITECTOR surge protection devices are space-saving and easy to install. They meet all requirements for risk minimization, increased efficiency, and future-proofing.
VARITECTOR surge protection devices allow fuseless operation up to 315 A, have a prewarning indicator and optionally a remote signalling contact for easy function monitoring.
The proven surge protection devices of the VPU series are now also available in variants with integrated type I back-up fuse with 25 kA. This eliminates the need for an additional back-up fuse upstream of the SPD. The combined type I+II surge protection devices have one back-up fuse per protective path and can be used universally in power distribution systems.
In industrial facilities, private and public buildings as well as in systems for regenerative energy generation, the power distribution systems must be equipped with suitable surge protection. This reliably prevents cost-intensive lightning and overvoltage damage. The combined type II+III surge protection devices have one back-up fuse per protective path and can be used universally in power distribution systems.
Surge protection is becoming more and more important due to increasing digitalization. On the one hand, because the sensitivity of intelligent devices, systems, and infrastructures is growing, and on the other, because cloud communication and the exchange of process data are playing an increasing role. The new surge protection devices of the type VPU IoT AC combine the functions of a powerful surge protection with those of an intelligent IoT device. This enables important functions to be monitored. Including the device status in real time, the number of overvoltages, the status of the protective earth connection, the history of temporary overvoltages (TOV), replacement recommendations, and much more.
PV systems are at high risk of lightning strikes due to their installation in exposed locations and must therefore be protected against surges in accordance with EN 51643-32. To avoid system failures, high repair costs and loss of sales due to surge damage, powerful PV arresters are the best solution.
Our new VARITECTOR VPU AC II+III surge protection devices provide optimum protection against lightning and surge damage. With a width of only 9 mm per pole, they are particularly compact and can therefore be used in all sub-distribution boards, charging stations, and many other applications.
Protects infrastructures. Secures your power supply.
To avoid failures due to overvoltage damage, you need reliable protection. The broad portfolio of VARITECTOR surge protection devices protects power, signal, and data transmission in all infrastructure systems - from power supply systems, signal boxes, and lock systems to digital control lines. The compact modules increase efficiency and reduce the effort required for maintenance, troubleshooting, and recertification. This alone pays for the investment after less than a year.
With our product wizard you can select the specifications of your desired lightning and surge protection products, and you will be shown an overview of all matching Weidmüller products.
Protection against lightning and surges is an existential and normative requirement for the construction of new buildings, plants and energy systems. This is also a matter of course for GFR.
