Funkcja falochronu

Ogranicznik przepięć typu 1 – podobnie jak falochron – ucina energię udaru do znacznie niższego poziomu. Chroni to instalację elektryczną i ograniczniki typu 2 i 3 zainstalowane za ogranicznikiem typu 1, wydłużając okres ich eksploatacji. Wszystkie ograniczniki typu 1 z serii produktów Red/Line posiadają funkcję falochronu (WBF).
