VS1+ High Voltage Vacuum Circuit Breaker Operating MechanismDetailed product description：

VS1+ High Voltage Vacuum Circuit Breaker Operating Mechanism
1、 Performance Introduction:
Our organization adopts a modular structure, which is extremely convenient for assembly and maintenance and is currently the most concise among similar switches. It has high reliability and a mechanical lifespan of up to 30000 cycles. It is matched with the ZN63S-12 indoor vacuum circuit breaker, which has a more reasonable structure and can be designed for miniaturized circuit breakers and side mounted circuit breakers. It is a new generation product with a completely new design.
