Abstract
(EN)
The present trip unit is an earth leakage device for switching off a mechanism in the case of detecting an earth leakage current. The closed housing (2) is protecting the movable parts of the actuation unit inside the housing from iron particles and dust coming from the environment. The specific positioning of parts of the actuation unit prevents iron and dust particles from contaminating the contact surface (Y) between the coil core (3) and the stator parts (61) of the actuator. The coil core and/or stator parts of the actuation unit are manufactured of iron in contrast to prevalently used expensive Fe-Ni alloy material.
(FR)
Le bloc déclencheur objet de l'invention est un dispositif concernant les pertes à la terre, permettant de mettre hors circuit un mécanisme en cas de détection d'un courant de fuite à la terre. Le boîtier fermé (2) protège des particules de fer et de la poussière provenant de l'environnement les pièces mobiles du bloc actionneur présentes dans le boîtier. Le positionnement spécifique des pièces du bloc actionneur empêche les particules de fer et de poussière de contaminer la surface de contact (Y) entre le noyau de bobine (3) et les pièces (4) du stator de l'actionneur. Le noyau de bobine (3) et/ou les pièces du stator du bloc actionneur sont constitués de fer et non d'un alliage Fe-Ni coûteux plus généralement utilisé.
