Vacuum interrupter/ operator
The vacuum circuit breaker consists of two
Interrupter/operator module
The interrupter/operator module consists of the three poles, each with its vacuum interrupter and primary insulators, mounted on the common motor or hand- charged
Construction
Refer to Figure 12: Interrupting/operating mechanism module (shown with outer- phase barrier removed) on page 17, Figure
13:Operating mechanism controls and indicators on page 18, Figure 14: Type 38- 3AH3 vacuum circuit breaker pole section on page 19 and Figure 15:
Each of the circuit breaker poles is fixed to the rear of the
The insulators also connect to the upper (20.0) and lower (40.0)
The
The mechanism is of the spring stored- energy type and is mechanically and electrically
