ZN85-40.5 Indoor AC High-Voltage Vacuum Circuit Breaker

Product Overview

ZN85-40.5(3AV3) Series Indoor High-Voltage Vacuum Circuit Breakers are indoor high-voltage equipment rated at 40.5KV, 3-phase AC 50Hz, equipped with a spring-operated mechanism for both electric and manual opening and closing operations. Suitable for industrial and mining enterprises, power plants, and substation electrical equipment control and protection, they are also ideal for frequently operated environments.

The actuating mechanism employs a specialized spring actuating mechanism designed for this new type of circuit breaker, installed within the frame. Its structural features and movement method are more suitable for the vertical and horizontal arrangement of this circuit breaker, and its performance aligns more closely with the characteristics and requirements of a 40.5KV vacuum circuit breaker.
