  "description_excerpt": "The present disclosure relates to a method for producing an electrical circuit-breaker device including at least one pole part with a respective housing arrangement for encapsulating an interrupter insert having two corresponding electrical contacts, and an adjacent actuator part for mechanically moving one of the electrical contacts via an intermediate operating mechanism. Furthermore, the present disclosure relates to a multi-chamber housing for such a medium-voltage or high-voltage circuit-breaker device.\n\nVacuum circuit-breakers improve the interruption process substantially through reduced contact travel, reduced contact velocity (compared to former minimum oil type breakers) and small masses of moving the electrical contacts. Accordingly, the vacuum circuit breaker requires a significantly smaller, lower energy actuator part with significantly reduced wear, which is usually designed as an electromagnetic device with at least one electrical coil surrounded by a ferromagnetic joke assembly which corresponds with a movable ferromagnetic armature in order to generate a suitable mechanical actuating force by electrical energy.\n\nEP 0 898 780 B1 discloses a magnetically actuated circuit breaker for medium voltage applications in the range between 1 and 72 kV of a high current level. A single electromagnetic actuator drives a common jackshaft. This jackshaft internally couples the actuator force to the moving electrical contacts of each vacuum interrupter on all three poles through insulated push rods.",
