Vacuum circuit breakers series BP6V are designed for switching AC electrical circuits with a nominal voltage of 6 (10) kV and frequency 50 (60) Hz in normal and emergency modes of operation in systems with isolated or partially grounded neutral.
Switches ??6? are mainly used to replace electromagnetic switches VES-6 in cabinets KE-6S at thermal and nuclear power plants.
BP6V are manufactured in earthquake-resistant version and are used for operation in premises at the height of 0...20,4 m at the maximum design earthquake (MDE) of 9 points on MSK-64 scale.
Switches consist of three poles with cast vacuum arc suppression chambers (VAC), placed on a common base. In BP6V circuit breakers for rated current 2500 and 3150 A VDC with current-carrying contacts are installed on insulating racks.
