The overvoltage protection and lightning protection is essential when building new plants and energy systems and is required by standards. Weidmüller offers the new Varitector VPU AC S with many advantageous features such as space savings or reduced maintenance.

For the planner and installer, when implementing surge protection, the Minimizing risk and future-proof technical properties to increase efficiency are the focus. Especially in energy supply and generation renewable energies, in the process industry and Building technology an increasingly efficient surge protection is required.

The Varitector type PU AC IS-Line is currently the only type I protection product against overvoltage and lightning on the market to offer plug-in protection of 25 kA with a width of 1 module. The components are certified according to IEC 61643-11. However, they offer much more than standard devices such as fuseless operation up to 315 A. Additional installation space, installation effort and separate backup fuse in systems are not required.

Surge protection easy to install and maintain

The pluggable arresters save assembly time and maintenance effort. A smarter one locking mechanism allows the system to operate reliably even in harsh environments. A coding system prevents arresters from being mixed up.

The lightning and surge protection is suitable for applications in which a high system availability is required. It has no leakage current and according to the new technical application rule VDE-AR-N 4100 can be installed in the pre-meter area. The S-Line thus combines the best properties of voltage-switching and voltage-limiting technologies into ideal class I surge protection.

The integrated phase GDT technology is compact and based on voltage switching technology with very low residual voltage. The surge protection achieves a market-leading low one Follow current strength. 16 A fuses of operational class gG are also not triggered.

The maximum allowable Continuous voltage Uc = 275 VAC also offers plenty of reserves. In the event of an overvoltage event, the devices offer a protection level of Up <1.5 kV.

The Varitector PU AC I S line is for sensitive infrastructure suitable, which increases with growing digitization. Overvoltage protection is compact, efficient and inexpensive.
