Main technical data

1. The fuse under specified operating conditions is able to reliably break any fault current from the minimum breaking current (2.5～3) ln to the rated breaking current 50kA.

2. Time - current characteristic curve is as shown in Fig. 3.

3. Current limiting characteristic curve is as shown in Fig. 4.
