Switch fuse unit is compact combination, generally metal enclosed of a switch and a fuse.
It is very widely used for low and medium voltages.
The ratings of switch fuse units are in the range of 30,60,100,200, 400, 600 and 800 amperes.
Switch fuse units are available as 3 pole and 4 pole units.
They are developed for making capacities upto 46 kA.
They can safely break, depending upon ratings, currents of the order of 3 times the load current.
Switch fuse units can be installed on metal-clad switchgear.
The accurate current limiting operation and high breaking capacity office has resulted in a number of ingenious combination of switches and fuse to get an economical unit combining the best performance of each.
