CHV-12 Indoor High Voltage Side Mounted Vacuum Circuit Breaker
Short Description:
The CHV-12 series indoor mounted high-voltage vacuum circuit breaker is an indoor high-voltage switchgear suitable for use in three-phase power systems with a rated voltage of 12kV and a frequency of 50Hz. It is used as a protective and control electrical device. Due to the special advantages of vacuum circuit breakers, it is particularly suitable for places that require frequent operation at rated current or multiple disconnections of short-circuit current.
Product details
Basic parameters：
The CHV-12 series indoor mounted high-voltage vacuum circuit breaker is an indoor high-voltage switchgear suitable for use in three-phase power systems with a rated voltage of 12kV and a frequency of 50Hz. It is used as a protective and control electrical device. Due to the special advantages of vacuum circuit breakers, it is particularly suitable for places that require frequent operation at rated current or multiple disconnections of short-circuit current.
The CHV-12 series side mounted vacuum circuit breaker adopts a fixed installation and is mainly used for fixed switchgear. This circuit breaker can be used alone or for ring network power supply, box type transformers, or various non-standard power supply systems.
