摘要:
In general, the disclosure is directed to sealed enclosures and devices that include enclosures for protecting enclosed heat sensitive components from the heat generated by enclosed heat producing components. Heat producing components within the enclosure may be placed to achieve uniform distribution of heat produced by the heat producing components, to optimize the dissipation of heat from the heat producing components to the enclosure, and to minimize the heat experienced by the heat sensitive components. The exterior of the enclosure may be designed to increase thermal dissipation and to protect against thermal radiation.

A circuit breaker includes a breaker housing, a stationary contact, a movable contact, an operating shaft, and a linear position sensor. The stationary contact is non-movably mounted within the breaker housing, and the movable contact is movably mounted within the breaker housing. The movable contact is coupled to receive an input force and is configured, upon receipt of the input force, to move between a closed position, in which the movable contact is electrically coupled to the stationary contact, and an open position, in which the movable contact is electrically isolated from the stationary contact. The operating shaft is coupled to the movable contact to supply the input force thereto. The linear position sensor is connected to the operating shaft and is configured, upon movement of the operating shaft, to supply a position signal representative of movable contact position.
