The upper part of the V20 surge arrester made of halogen-free plastic is suitable for surge protection equipotential bonding according to 0100-443 (IEC 60364-4-44) and serves as a spare part for the V20 SurgeController. A dynamic disconnection device and an optical status display characterize the modular plug-in arresters. 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 the upper and lower parts. The wedge-shaped design of the contacts makes it easy to insert and even easier to remove the upper parts.
