Description
Vacuum Circuit Breakers 10kV are used in electric installations for electric circuits switching. They operate basing on the principle of vacuum contact breakaway in the space between stops. Vacuum Circuit Breaker 10 kV protects electrical equipment against overload and short-circuit.
Vacuum Circuit Breakers ВВ-СВЭЛ-10 are used in switchgears with voltage up to 10kV. In switchgears where electrical circuits are assembled and controlled, vacuum circuit breakers are used to control the electric current and ensure the safe operation of the electrical network.
Vacuum circuit breaker for switchgears create switching of electrical circuits in the switchgear and also detect malfunctions in the equipment.
Vacuum circuit breakers are used in industrial electrical installations. They protect electrical equipment on plants, power stations in AC networks through arc-supression coil with frequency of 50Hz. The choice of type or brand of vacuum circuit breaker depends on the electrical system. Several factors are taken into account when purchasing: power, voltage, additional features and functions.
ВВ-СВЭЛ-10 features a linear design that significantly reduces the space required for its installation. Vacuum circuit breaker also has a high vacuum level for safe operation of electrical devices. In addition, the vacuum circuit breaker has a rated current of up to 630 A, which allows it to be used in various switching distribution devices. In general, vacuum circuit breaker is a convenient and reliable tool in electrical engineering, which is used in a wide range of applications. It ensures safe operation of the electrical network in areas where switching of electric current at voltages up to 10 kV is required.
