This 5KV motor vacuum contactor is a direct replacement for the Westinghouse Ampgard 2 Model CR motor control air contactors.  The new vacuum contactors reduce maintenance, improve safety and prolong the life of the contactor without changing the MCC or switchgear lineup.  The new vacuum contactors eliminate heavy arc chutes containing asbestos and contain the electrical arc within vacuum bottles for safer and faster operation.  Vacuum contactors offer 250,000 electrical operations before requiring contact maintenance or replacement.
