Dropout fuse is the most commonly used short-circuit protection switch for 10kV distribution line branch lines and distribution transformers.
Features:
Provide protection to the line of distribution system and the various apparatus on those line such as transformers and capacitor banks.lt can also be used as a sectionalizing device.Using a portable loadbreak tool,it can function much like an overhead line disconnect switch.
Maximum design voltage from 10Kv-38kv;Maximum Rating current 100-200A
