In traditional control circuits, actual volt-amperes (VA) are applied/injected to the command coils. However, when testing magnetically-actuated vacuum circuit breakers, only a "lower power" voltage signal is required. Instead, we need to interface with "Remote TRIP" and "Remote CLOSE" pins (5, 7, and 9) with the associated control

In fact, the vacuum circuit breaker (VCB) is today recognized as the most reliable, and it also needs the lowest maintenance among all the technologies available to control and protect distribution circuits. The present consensus all over the world is that the VCB breaker will dominate medium voltage technology in the twenty-first century.

The invention relates to a compression bar type energy storage operating mechanism for a vacuum circuit breaker. The compression bar type energy storage operating mechanism is characterized by comprising a manual compression bar (1) which is in transmission
