Title (EN) POWER SWITCH
(FR) DISJONCTEUR
(DE) LEISTUNGSSCHALTER
Abstract:
(EN) The invention relates to a power switch for interrupting an electrical circuit when current and/or current time span threshold values are exceeded, comprising an energy converter, which on the primary side is connected to the electrical circuit, and on the secondary side provides an energy supply for at least one control unit of the power switch. The energy converter has a core having a remanence flux density (Br2) of less than 30% of the saturation flux density (Bs2 ) or a coercive field strength (Hc2) of less than 10 A/m.
(FR) L'invention concerne un disjoncteur permettant de couper un circuit électrique en cas de dépassement de valeurs limites de courant et/ou de périodes de courant, comportant un convertisseur d'énergie qui est raccordé au circuit électrique côté primaire et assure côté secondaire une alimentation en énergie d'au moins une unité de commande du disjoncteur. Le convertisseur d'énergie présente un noyau dont la densité de flux rémanent (Br2) est inférieure à 30 % de la densité de flux à saturation (Bs2) ou dont l'intensité du champ coercitif (Hc2) est inférieure à 10 A/m.
(DE) Die Erfindung betrifft einen Leistungsschalter zur Unterbrechung eines elektrischen Stromkreises bei Überschreitung von Strom- oder/und Strom-Zeitspannen-Grenzwerten mit einem Energiewandler, der primärseitig mit dem elektrischen Stromkreis verbunden ist und sekundärseitig eine Energieversorgung für mindestens eine Steuereinheit des Leistungsschalters zur Verfügung stellt. Der Energiewandler weist einen Kern auf dessen Remanenzflussdichte (Br2) kleiner als 30% der Sättigungsflussdichte (Bs2) ist oder dessen Koerzitivfeldstärke (Hc2) kleiner als 10 A/m ist.
