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. .
