    Abstract: A circuit breaker having high amperage capacity includes a metallic snap-action element, capable of opening an electrical circuit upon thermal or current overload, disposed within a sealed glass envelope. Two metallic tubes are sealed to, and pass through, one end of the envelope. Lead-in conductors, which also serve as supporting members for the breaker assembly, extend through, and are sealed to, the metallic tubes.
