Terminal equipment protection T3

For protection of terminal equipment, we recommend using additional surge protection type T3. For example, HSAA-1P designed for installation in rail ducts and floor boxes. In the same design we also offer a special variant for the protection of LED lights - HSAA-2 NPE LED S. The HSAD series, available in parallel or series versions, is designed for switchboard and offers a version with replaceable modules in addition to remote signalling.
