Vacuum Circuit Breaker indoor high voltage HVD11 1.14KV 630A VCB from Hubei JUCRO ElectricDetail Information
HVD11 1.14KV 630A Permanent magnet mechanism indoor high voltage vacuum circuit breaker VCB from Hubei JUCRO ElectricVacuum Circuit Breaker accept customized order according to technical drawing or samples.General:
HVD11 1.14KV 630A Permanent magnet mechanism Vacuum Circuit Breaker is mainly used in 1140v or 660v three phases electrical distribution system. Permanent magnet low-voltage vacuum circuit breakers can be operated under the rated current range frequently breaking the short-circuit current, more suitable for use in coal mine feed systems, composed of mining and high voltage flameproof distribution. ALso could use for Large-capacity motors for start infrequently.
This product uses bistable permanent magnet mechanism + short-circuit magnetic manual opening, simple structure, stable and reliable. Because there is no axle, hook and other mechanical parts, greatly reduced the mechanical parts failure caused by wear and tear, Longer service life.NO.ItemData1Rated voltage1140v AC2Rated current630A3Convention thermal current630A4Rated short circuit breaking current12.5KA(1140V, COSφ=0.3)5Rated short circuit breaking times16times(Closing-Opening 10 times, Opening 6 times)6Rated frequency50HZ7Electrical life≥3000times AC-28Mechanical life≥10000times AC-29Inherent closing time≤100ms10Inherent opening time≤30ms11Three phases unsynchronized time<1.5ms12Resistance of single phase closing circuit≤100μΩ13Opening distance3.0~4.0mm14Over travel distance1.8~2.2mm15Auxiliary contacts3NO+3NCPacking & Delivery
