  • the contact lever carrier which can consist of metal or insulating material, has a number of receiving openings for the contact force springs, which are designed as helical compression springs. If the contact levers are relatively narrow, it proves to be expedient to distribute the total contact force required over two parallel contact force springs per contact lever. It is then possible to use springs whose diameter does not exceed the width of the contact lever. Since low-voltage circuit breakers can have different numbers and differently wide contact levers depending on the respective rated current and switching capacity, the number of recesses to be provided for receiving the contact force springs in the contact lever carrier is accordingly very different. This means that different Kunststoffhebeltr ger must be provided even if the total width of the movable with different sizes of circuit breakers Sehal contact arrangements match, but the number of

Abstract

Dispositif de contact de commutation mobile (7) pour commutateur de puissance basse tension (1) présentant un support (11) pour plusieurs leviers de contact (10) et doté de ressorts à force de contact (17) coopérant avec les leviers de contact (10). Le support (11) est muni d'un évidement en forme de poche (22) destiné au logement d'une pièce intercalaire (21) servant de butée pour les ressorts à force de contact (17). Différentes pièces intercalaires (21) permettent l'utilisation de supports identiques à leviers de contact pour des garnitures différentes avec des leviers de contact (10) et des ressorts à force de contact associés (17).
