Indoor High vacuum circuit breaker

1 Outline The SC40305-40.5/ 1600-25 2000-3105 indoors high vacuum circuit breaker is rated voltage 35kV, in the three phase ac 50Hz system indoors installment, is suitable to place and so on industry and mining enterprise, power plant, transformer substation, uses in control and protection which the high-tension motor, the transformer, the capacitor installs, has the following merit:

a).Does not have the pollution, does not have the fire and the explosion hazard;

B) longer machinery, electrical life, electrical life 6,000; C) moves overhauls the quantity to be extremely few, achieves nearly does not need to service; D) may frequently operate; E) holds the drive mechanism to be possible to select the CT19BN spring to hold the drive mechanism or the CD10 III electromagnetism holds the drive mechanism; This product conforms to GB1984-89 "A.c. high voltage Circuit breaker" and DL402-91 "A.c. high voltage Circuit breaker Ordering Engineering factor" request.
