ZN-10C series indoor handcart type high-voltage vacuum circuit breakerDetailed product description：

The ZN-10C series indoor handcart type high-voltage vacuum circuit breaker is a high-voltage indoor switchgear with a rated voltage of 10KV three-phase slurry 50HZ. It is widely used in mining enterprises, power plants, and substations as a protection and control device for high-voltage electrical equipment, especially suitable for breaking heavy loads and frequent operations.
This series of circuit breaker operating mechanisms can be equipped with CD10, CD17 electromagnetic operating mechanisms or CT8, CT17, CT19 spring operating mechanisms, and comply with relevant standards such as IEC-56 and GB1984-89 ≤ AC high-voltage circuit breaker ≥.

Normal usage conditions
The altitude should not exceed 1000m;
The upper limit of ambient temperature is+40 ℃, and the lower limit is -25 ℃;
Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%
The surrounding air should not be significantly polluted by corrosive or combustible gases, water vapor, etc;
There is no frequent severe vibration.

structural characteristics
The ZN-10C series indoor handcart type high voltage vacuum circuit breaker is a handcart driver type structure that can directly enter the KYNI-10 or JYN2-10 handcart cabinet. Handcarts of the same specifications are completely interchangeable. The handcart has a reliable locking device, and the entry and exit of the cabinet are driven by a worm gear mechanism.
