The V20 surge arrester made of halogen-free plastic is suitable for surge protection equipotential bonding in accordance with 0100-443 (IEC 60364-4-44). A dynamic disconnection device and optical status display characterize the modular plug-in arresters. The NPE variant is also equipped with a heavy-duty spark gap between the neutral and protective conductors. The SurgeController is particularly suitable for equipotential bonding in main and sub-distribution boards, depending on the type in the areas of TN and TT networks. Thanks to the high-performance varistors, the discharge capacity is up to 40 kA (8/20) per pole. The vibration-proof locking and the voltage and type coding ensure safety and prevent confusion between upper and lower parts. The wedge-shaped design of the contacts makes it easy to insert and even easier to remove the upper parts. Additional technical product information can be quickly and easily accessed using mobile devices via the QR code on the rating plate.
