A special feature of the breaker truck is the double action auxillary plug which makes the system fully draw out. There is no cumbersome manual plugging as the draw out operation itself takes care of everything. The draw out operation makes first and breaks last.
The Indoor Vacuum Circuit Breaker is completely type tested at CPRI, Bangalore.
