Programmable Low-Voltage Circuit Breaker and Tester

An instrumentation system that would comprise a remotely controllable and programmable low- voltage circuit breaker plus several electric- circuit-testing subsystems has been conceived, originally for use aboard a spacecraft during all phases of operation from pre-launch testing through launch, ascent, orbit, descent, and landing. The system could also be adapted to similar use aboard aircraft. In comparison with remotely controllable circuit breakers heretofore commercially available, this system would be smaller, less massive, and capable of performing more functions, as needed for aerospace applications.
