Mounting the Open Fuse Auxiliary Switch
The open fuse auxiliary switch can only be installed on the A-
mechanism and a fuse base equipped with fuse tripping. This
switch has two contacts, one normally open and one normally
closed. It is actuated by the fuse tripping tie rod linkage con-
nected to the type CEF fuse base.
1. Locate the mounting hole and slot on the side of the A-
mechanism with the operating shaft shown in figure 11.
2. Bolt the open fuse auxiliary switch to the mounting hole on
the A-mechanism and loosely install the screw hardware to
allow the switch to rotate into the slot, pictured in figure
12.
3. Place the white disk onto the half-moon shaft and rotate
the switch into place as shown in figure 13.
4. Rotate the white disk with your finger and mark the hole
directly adjacent to the white roller on the switch as
shown in figure 14.
