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).Trap protection circuit breaker, especially for insulation monitoring of electric circuits (2) down a sum current converter (1). The total current converter has at least one primer selection, formed phase conductor and neutral conductor, and a secondary winding, which controls via a control circuit (6) a holding magnet (20) acting on the switch contacts (22). The holding magnet (20) is connected to a power supply as well as a storage circuit (9).
