跌落式熔断器 GAOCI

principle

the primary purpose of any fuse cutout is to provide protection to the line of your system and the various apparatus on those line such as transformer and capacitor banks. fuse cut out provide reliable protection from low-level overloads that just melt the fuse link, intermediate faulte, and very high faults, through maximum interrupting capacity. drop-out fuse cutout is composed of insulator supports and fuse tube. static continueacts is fixed on two sides of insulator support and moving contact is in stalled on two ends of fuse tube. fuse tube is composed inside arc-extinguishing tube, outer phenolic compound paper tube or epoxy glass tube. load switching fuse cutout provides enforedelastic auxiliary contacts and arc-extinguishing exclosure for switching on/off loading current
