THE DESIGN OF THE VAH CIRCUIT BREAKER IS BASED ON THE S-CHNEIDER ELECTRIC TRADITION
Circuit breaker pole structure. The poles are supported in the same branch by insulators on the shelf. Compact structure.
The vacuum interrupter is securely mounted on the pole by means of a sturdy support to ensure that it is not disturbed by any external force. During the breaking and closing periods, the force generated by the arc only acts on the arc extinguishing chamber contactDivide.. This simple and flexible structure of the circuit breaker can be different Provide solutions for the special needs of users.Operating mechanism The spring operating mechanism and other auxiliary mechanisms are integrated into the mechanism box.Include:
• Operating mechanism
• Energy storage motors
• Auxiliary switches
• Trip coils
• Operation counters
• Mechanical operation and indication mechanism.
