3.Main technical data 
(1)Under the condition of specified conditions, the fuses can break any fault current from the current that can cause fuse-element melted to the rated breaking current of 50kA.  
(2)Time-current characteristics curve is shown in (Fig.1),The dotted lines stand for the current above the minimum breaking current.  
(3)Current-limiting characteristics curve is shown in (Fig.2).
4.Shape and mounting size
The shapes and dimensions of the fuses are shown in (Fig.3)and
