Electrical circuit breaker for use in automatic switching systems

摘要

The circuit breaker has an insulated housing (10) with end caps (20,21). Within this is a fixed contact (110) supported on an electrode stem (150). The movable contact (210) is fixed to an electrode disc (240) with pins. The electrode is integral with a stem (250) that moves axially and is sealed by a bellows (45), allowing the housing to be filled with an inert gas.
