Abstract

Fellstrømbeskyttelsesbryter, især for Isolasjons- overvåknlng av elektriske strømkretser (2) ned en sumstrømomformer (1). Sumstrømomformeren har minst en prlmærvlkllng, dannet faseleder og nøytral leder og en sekundærvikling, som styrer via en styrekrets (6) en på bryterkontaktene (22) virkende holdemagnet (20). Holdemagneten (20) er forbundet med en strømforsyning såvel som en lagerkrets (9).
