With increasing digitalisation, the infrastructure of intelligent devices and systems is becoming more and more sensitive to interferences. Besides, cost and competition are forcing manufacturers to improve compactness and efficiency of their products. The innovative HAD-Technology of our VARITECTOR PU AC S line enables a particularly space-saving design with only 18 mm width per pole. For excellent surge protection with a slim design and an attractive price / performance ratio.
The reduction of the components from 2 TE to 1 TE per pole with 25 kA discharge capacity allows a 50 % smaller space requirement. The pluggability of the modules accelerates the replacement of arresters.
With a protection level of 1,500 V, the VPU AC S line is coordinated as an arrester of type I, II and III. Additional protection is therefore only required only for wiring distan-ces of more than 10 m to the next electrical consumer.
The components are certified according to IEC 61643-11 of course, but they offer much more than standard devices: fuseless operation up to 315 A, for example. As no separate back-up fuse is required, there is no need for additional space, installation work and costs.
Weidmüller‘s VPU AC S line was developed to combine the best features of voltage switching and voltage limiting protection technologies and create an ideal Type I surge protection. The innovative HAD technology (Homogenous Arc Distribution) is extremely compact and uses a voltage switching technology with a very low residual voltage. This enables the products to achieve a low follow current strength, which means that even a 16 A fuses will not trip.

Bosch Building Automation GmbH has also been convinced by the product: "Especially for us in switchgear construction, the reduced wiring effort and the space savings due to the elimination of the back-up fuse are a great advantage. Thanks to the good connection technology, we also achieve an increase in efficiency,
