Medium Voltage Breaker to Vacuum Starter Replacements

An excellent tool for starting 5kV/7.5kV class motors is a new line-up of fused vacuum contactors, but this requires an outage, new equipment, new cables, changes in the power switchgear coordination and often a loss of drawout and metal-clad switchgear features. To get the best result, a combination power circuit breaker/vacuum contactor is a better solution.
