Drop-out Fuse cutout and load switching fuse cutout are of outdoor used high voltage protective device. To be connected with incoming feeder of distribution lines it mainly protect transformer or lines from short circuit nd overload, and on/off loading current. Drop out fuse cutout is composed of insulate insulator supports and fuse tube, static contacts is fixed on two sides of insulator support and moving contact is installed on two ends of fuse tube. Fuse tube is composed of inside arc-extinguishing tube, outer phenolic compound paper bute or epoxy glass but. Load switching fuse cutout provides enforced elastic auxiliary contacts and arc-extinguishing enclosure for switching on/off loading current.TypeRated voltage (KV)Rated current (A)Breaking current (A)Impulse voltage (BIL)Power-frequency withstand voltage( kV )Leakage distance (MM)Weight (KG)Dimensions (CM)SC-33331006000180758501765×37×17SC-333320080001807585017
