Product Description

product description:

ZN63-12 indoor high-voltage vacuum circuit breaker is an indoor switchgear for a three-phase AC 50HZ power system with a rated voltage of 12kV. It is used as a protection and control unit for power grid equipment and industrial and mining enterprise power equipment. It is suitable for places where frequent operations are performed under rated operating current or where short-circuit current is repeatedly interrupted. The circuit breaker adopts the integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a special propulsion mechanism to form a handcart unit.

Operating environment:

1. Ambient air temperature: upper limit +40°C, lower limit -15°C;

2. Altitude: ≤1000m (if the altitude needs to be increased, the rated insulation level should be increased accordingly)

3. Amplitude: the seismic sequence shall not exceed 8 degrees;

4. The daily average relative humidity of the air is not more than 95%, and the monthly average is not more than 90%.
5. Places free of fire, danger, severe pollution, chemical corrosion and severe vibration.

Transport and storage:

1. Traffic

The entire circuit breaker must be packed in a closed packing box and fixed during transportation.

2. Storage
The circuit breaker should be stored in a dry, ventilated, moisture-proof, shock-proof, and harmful gas-proof room. Long-term storage should add lubricating oil to the transmission part, and check whether the environment meets the requirements.
The storage period of the vacuum interrupter is 20 years.

Ordering information:

Users should indicate:

A sort of. Circuit breaker model, name, order quantity;

b. The rated voltage, rated current and rated short-circuit breaking current of the circuit breaker;
c. Rated working voltage of energy storage motor and opening and closing coil;
d. Number of overcurrent tripping coils and tripping current value;
e. The name and quantity of spare parts;
F. In case of any ambiguity or special requirements, please contact the manufacturer.
