Indoor Front-Mounted Vacuum Circuit Breaker

This indoor vacuum circuit breaker is arranged for front mounting, with primary connections and the operating face matched to the panel structure. Review mounting datums, phase positions, terminal projection, mechanism access and the secondary connector, then define the required interruption duties for the circuit. Specify the breaker, mechanism, coils and auxiliary contacts supplied. Protection, measurement equipment and other panel components are separate scope items rather than implied parts of the breaker.
