Main technical performance：

Fig.3 the fuse and backup fuse protection feature

Note: Point A: the intersection of two curves

Point B: rated minimum breaking current of backup fuse

Point C: rated maximum breaking current of fuse

During the operation, point A must be present and point B is above point A

Point C is below point A.

Installation and use

1. When mounting the fuse into the tank, ensure the oil level is within the range as shown in Fig. 2

2. When replacing the fuse, open the buckle on the handle and turn the handle for 90° to eliminate the adhesion between the sealing gasket and outer tube. Remove and replace the handle.

3. For the installation of three-phase fuse, replace all three phases unless you can confirm that the fault current passes through one phase.
