Abstract
A THOROUGHLY TESTED light-weight circuit breaker for the 208Y-120-volt 3-phase 400-cycle a-c system for large aircraft is now a reality. The circuit breaker is electrically operated, remotely controlled, with latched-in main contacts. The design is suitable for paralleling generators and busses, circuit interruption, manual or automatic synchronization, and interlocks are provided for use in various control circuits. Operating solenoids are designed for low current requirements and for wide ranges of voltages and ambient temperatures. Size and weight have been kept to a minimum.
