Product Description:

NEX1-12 side-mounted vacuum circuit breaker is an indoor high-voltage switchgear, suitable for three-phase power systems with a rated voltage of 12kV and a frequency of 50Hz. It is used as a protection and control device. Due to the special advantages of vacuum circuit breakers, it is especially suitable for Frequent operation under rated current, or places where short-circuit current is broken many times.

NEX1-12 side-mounted vacuum circuit breaker adopts fixed installation and is mainly used for fixed switchgear. The circuit breaker can be used alone, and can also be used for ring network power supply, box-type transformer or various non-standard power supply systems.
