MVXN6-12

MVXN6-12 side-mounted indoor high-voltage vacuum circuit breaker is an indoor high-voltage switching device. It is suitable for use as protection and control appliances in three-phase power systems with a rated voltage of 12KV and a frequency of 50Hz. Due to the special advantages of vacuum circuit breakers, It is especially suitable for places that require frequent operation at rated current or multiple short-circuit currents.

MVXN6-12 side-mounted indoor high-voltage vacuum circuit breaker adopts fixed installation and is mainly used in fixed switch cabinets. This circuit breaker can be used alone or in ring network power supply, box-type transformer or various non-standard power supply systems. .

normal usage conditions

1. Ambient air temperature; upper limit +40℃, lower limit -15℃.
2. Altitude ≤ 1000m (if the altitude needs to be increased, the rated level will be increased accordingly).
3. Amplitude: The earthquake intensity does not exceed 8 degrees.
4. The daily average relative humidity of the air should not be greater than 95%; the monthly average should not be greater than 90%.
5. There is no risk of fire, explosion, severe pollution, chemical corrosion or severe vibration.
