Description
The HR3 series fuse switch disconnector is for AC 50 Hz, 400 V distribution systems with a rated current up to 1000 A. It provides short-circuit protection and overload protection for cables and conductors, and allows infrequent manual making and breaking of normal load and overload current, while the fuse clears short-circuit current.
