SURGE ARRESTER FOR LV-NETWORK USM-LED 230

When lightning strikes a building protected by external lightning protection, large potential differences can arise between the building and installed systems (electrical, telecommunications cables), leading to dangerous fires and damage. Nearby lightning strikes generate strong magnetic fields that can damage electrical equipment. But even lightning strikes up to 2 km away can create dangerous overvoltages in the building’s electrical equipment. OBO provides all necessary products for reliable lightning protection: lightning rods, surge protectors, potential equalization and grounding accessories. Type 2 surge protectors are used to limit overvoltages in electrical equipment. The ÜSM-LED 230 is designed for surge protection of LED outdoor lighting. It can be connected directly to the pole connection point, either in parallel or in series. When connected in series and the surge protector’s operational status changes, it also switches off the LED light, indicating the need for inspection or maintenance.
