ZN73(VS1)-24 series indoor high-voltage AC vacuum circuit breakerDetailed product description：

The ZN73 (VS1) -24 series circuit breakers are mainly used in power systems of 24kV and below, as protection and control for power grid equipment and power equipment in industrial and mining enterprises. The design meets the requirements of standards such as GB1984, JB/T3855, DL/T403, IEC62271-100, etc. The overall structure adopts the form of an operating mechanism box and a front and rear arrangement of the arc extinguishing chamber. The main electrical circuit part adopts an insulated cylinder three-phase floor structure. The electrical unit and the spring operating mechanism arranged on the plane are placed in the mechanism box in front of the arc extinguishing chamber, making the operating performance of the operating mechanism very close to the required performance of the arc extinguishing chamber opening and closing, ensuring the reliability of the circuit breaker operating performance.
