Outdoor high-voltage vacuum circuit breaker (also known as Outdoor pole-mounted high-voltage vacuum circuit breaker) is mainly used for breaking and closing the load current, overload current and short-circuit current in the power system in the distribution network. It is suitable for protection and control in substations and power distribution systems of industrial and mining enterprises. It is more suitable for rural power grids and places with frequent operations. It is especially suitable for the needs of urban and rural power grid transformation. Rated voltage three-phase AC outdoor power distribution equipment.

Various types of circuit breakers are available. Welcome to inquire about product information
The circuit breaker can be equipped with an isolation switch according to user needs Or anti-inrush time delay protector, etc.
The three-phase common box type three-phase vacuum arc extinguishing chamber is placed in a metal box and uses insulating materials to insulate between phases and to ground. The insulation performance is reliable and the insulation strength is high.
The circuit breaker can be equipped with a manual spring mechanism or an electric spring mechanism. The electric spring mechanism can be equipped with a wireless remote control.
The circuit breaker can be combined with the corresponding controller to form an automatic recloser, segmenter, etc. according to user requirements to realize distribution network automation.
The intelligent circuit breaker has a secondary reclosing function and the recloser parameters can be adjusted.
The protection parameters with the functions of closing inrush control overcurrent protection and short-circuit quick-break three-stage composite protection can be continuously set by the user.
This circuit breaker (small hydropower type) can be used to monitor line voltage. When overvoltage or undervoltage occurs, the controller automatically opens the circuit breaker. The circuit breaker can be widely used at the grid-connected branches of small hydropower branches and the main power grid to realize network connection. Road monitoring and automatic fault isolation.
A lightning arrester can be installed. The lightning arrester can be installed on any side of the incoming and outgoing lines according to user requirements.
The circuit breaker can be equipped with a measuring or metering transformer.
