Industrial plants and building infrastructures are becoming increasingly complex. This makes them more sensitive to surge damage. In addition, digitization 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 pre-warning indicator and optionally a remote signaling contact for easy function monitoring.
The growing number of sensitive devices requires ever better lightning and surge protection for power feeds. This applies to industrial plants as well as to private and public buildings and regenerative power generation.
Data interfaces are extremely sensitive. So they must be particularly well protected against overvoltages. At the same time, it is essential to ensure there is no negative influence of the protective circuitry on the data transmission.
Our new VARITECTOR PU AC II+III surge protection devices provide optimum protection against 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.
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.
Surge protection is a mandatory component in all commercial and private real estate according to DIN VDE 0100-443 und -534. The space-saving installation on the 40 mm rail system guarantees the best protection with the smallest space requirement.
For simple protection of intelligent metering systems such as gateways, control boxes or control units for remote shutdowns, the V-ZPA Fuse Holder provides two standard-compliant voltage taps.
In modern building installations, space-saving and easy-to-install components are required that comply with the new VDE application rule. The V-ZPA Terminal type feed-in adapters have been specially developed for these requirements.
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.
